Big Bore Airguns / Re: Texan tuning and possible mods
« on: November 18, 2017, 05:55:37 PM »
So I've made a lot of progress lately. After degunking the barrel, adding a Mad Dog Ultima stock, setting up a new Air Venturi compressor, I finally got down to some shooting. I used the swaged bullets from Nielson and they results were fantastic. My best series was 5 shots at 155 yards (pic below of steel target). I had one shot about 4" high, three shots 2.5" left touching, and one shot low right 4" (in that order). The group itself isn't remarkable, but the three touching was cool. I'm shooting off of a Harris bipod with a bench leg (thank you, Doug a.k.a. Mad Dog) on the rear stock. I know that I can keep improving on that but I'm also confident in my gun enough now to take it on some coyote hunts and stay within my comfortable max range (150 yards).   

I've noticed that there are very few posts anywhere regarding the .308 Texan setups. I'm certainly no expert (although a few have helped me out and for that I am really grateful) but I thought I would post what I've found seems to work. Hopefully it helps someone else save some time, aggravation, and money.

.308 Texan
Hawke Vantage IR 4-12x50 AO scope
Weaver mounts
Airforce Picatinny rail adapters (2)
Mad Dog Ultima Stock with 4" picatinny rail w/sling stud on foreend, bench leg and sling stud on rear stock,
All internals and barrel are out-of-the-box stock.

bullets used: 122 gr., 138 gr., and 154 gr. Nielson swaged hollowpoints. I found amazingly that all of the bullet weights grouped really well. It was just a matter of adjusting mil dots for each bullet. I hadn't had that when using cast bullets, but I will also grant that my barrel had probably been fouled for some time. That being said my barrel was spotless after shooting more than 100 shots of Nielson ammo, so maybe the swaged bullets deposit less lead in the barrel??? I'm not sure, but I'm not fixing what isn't broke.

best air pressure seems to be between 2600 and 2700 psi but still good down to 2500. Because I have the compressor I can now get my big 74 cu. ft. tank set right at the happy spot. I also untethered and my results were just as good, but to be fair I was only firing two shots before refilling. I was mimicking my hunting scenarios and I'm looking at one good shot and a follow up if needed.

I keep my scope at 7x all of the time and use the yardage adjustment (parallax?) on front of the scope for yardage.  I have a lot to learn yet on how to use my optics correctly and until I do I'm keeping it simple. Fiddling with it too much hasn't worked out particularly well for me and I'm a little gun shy (no pun intended)

3000 psi fills don't work very well for me. I don't trust my chrono numbers right now so until I get that resolved I'm not relying on it for any info. Just basing off of what the groups are like, 3000 psi fill shots are more wild and things flatten out nicely around 2700 . However, I have had good results using cast 118 gr. bullets at 2000 to 2100 psi (tethered prior to have a compressor)

Obviously from now on I'm checking my barrel after each outing. There is a big difference in the feel and appearance of swaged bullets and cast bullets. Groupings of each in 154 gr. at 100 yards were similar enough to be considered equal. However, it's hard to beat the hollowpoint for hunting. Also, the bullets left zero residue in the barrel.

The experts here at AGG are right...having a compressor is game changer if you shoot big bore. You can get away with it for a while (I did) but eventually even the easiest and most reliable air sources become a pain in the ass.

Pics below are my gun, 155 yard steel target, and 100 yard two-shots-untethered.

OFF TOPIC / Re: OpEd
« on: November 13, 2017, 07:29:16 AM »
This is an interesting topic, one that has far ranging opinions and ramifications. Being a Californian in living in the Bay Area, it can be hard to reconcile living an outdoorsman lifestyle. Yesterday at the 49er game my buddy and I were viewed as backwoods hillbillies because our tailgate menu was venison backstrap, fresh crab, and wild turkey breast. 100% harvested game.

I'm 48 years old, and when I was in high school we took the hunter's safety course as part of our wildlife/conservation class (elective)  That seems like it was just yesterday and unfortunately that of course does not happen today.

The times are a-changin' in many, many ways.

As a last comment, when did the term 'active shooter' become a normal part of our civilian vernacular? I find that very sad and heartbreaking.

Where the depth gets you, the current gets me in the bay and sucks my floats down. Fixed that by running a stinger float on a three foot shot off of the main float.

I stay in Tomales Bay. I have a small boat, like you I'm scared of running over kayakers in the dark, and I seem to do ok on the crabs there. I went out Friday night at midnight, dumped five pots, and then anchored and used rods and reels with crab traps. My brother and I had 16 nice big crab by daybreak. We pulled through the gear and only got three crab out of the pots. Anchored again for five minutes and got our last crab on a snare.

Not as many crab as last year; I just don't think they've moved in yet. The guys working the deep water outside in 150' to 180' are getting good numbers but that's not for me and my smaller equipment/weak stomach.

So I basically had issues coming out of my wazoo. I started messing with the scope when the gun starting getting inaccurate and it snowballed from there. Long story short my barrel is fouled horribly. That's where my problem started and it only got worse. So I'm sure the scope is fine (if I didn't wear it out tweaking it) 

As far as Caniborrowsomeammo, he and the dog are always welcome. I'll drop him a line. I'm busy as heck for the next two weeks with work and the opening of crab season.

I've never tried to post a pic here before (hopefully it worked), but I think I found my accuracy problem. It looks like I melted fishing sinkers and poured them down the barrel. I'm embarrassed to say that I haven't noticed it up until now. It only took about 50 shots and having the scope/picatinny adapters off twice today and still not hitting the paper at 15 yards. Hopefully with a good cleaning things will start to make some semblance of sense again.

I'm exposing my ignorance because A) people have taken the time to help, and B) maybe someone else who's new like me can learn from this and avoid spending hours of time blowing air, bullets, and patience.

I wish this was as easy as setting tile!!  :o

Points taken Bob. My only criticism is comments that always seem to be 'yours is ok but mine is better', 'why would anyone want to buy that' or something to that effect. That isn't help at all, it's just condescending. After spending over 5k in 5 months on my hobby (using a lot of the great advice I've picked up here) the last thing I want to hear is yet another post about how my equipment sucks. Considering that, I admit I could be a just bit hyper sensitive. Moving on...

You're absolutely right on the ammo variety. When I purchased the gun I bought boxes of everything because like everyone says you just don't know what the gun likes. So yeah, I shot round balls through 198 gr.  I could spit faster than the 198 gr. so you are indeed correct that they really have no usable purpose for my stock Texan. Probably the same for the 174's. It seems that everyone keeps coming back to the 154 gr. as a the most consistent. I have also had good results with 118 gr. at lower air pressures (1800 to 2100 psi)  shooting my most consistent groups of any bullet both on and off of the bottle .

Sleeves, supports...I'm glad you brought that up. I'm trying to consolidate some ideas and about the only thing out there that seems to actually have some worth is the shroud from R&L. There are other items, but I'm not sure if they are gimmicks and/or just for looks. I know African Ordinance has some stuff too, but I try to keep things domestic as much as possible for both cost and business support (Canada counts! ;)   Are there options for carbon fiber sleeves that may work better? I personally don't know of any for my gun. As I said, sound suppression isn't an issue so is it possible to apply a sleeve and not lengthen to overall gun (or maybe just an inch or two)? Do you think that an after market one piece would stiffen anything or would that independent of the barrel?

Intended target - complicated question. Here's what I had hoped when I bought the gun: hunt deer with it where legal, enjoy some long range (100-200) yards bench shooting, plinking, and some misc. varmint hunting. The reality is a little different (and hindsight is always 20/20). Most states are .35 caliber and up for big game so I probably will never use it for deer, it takes a lot more skill than I imagined to get an air rifle like this one to shoot accurately, and as luck would have it (although you wouldn't think so) the .308 seems to be the least accurate of the Texan line. All of that being said, I still like it a lot even though I can be frustrated with it. It's a learning curve and it's teaching me patience, persistence, and forcing to learn about the ins and outs of PCP's.

When it gets too bad I just pick my .25 Armada that Int3man work over for me and start shooting ragged holes at distance to get my confidence back!  ;D

Right on Nick...thank you. We've spoken about the accuracy of the .308 before but I'm finding regardless of the eccentricities of the gun my limited knowledge of it sends me spinning in different directions. It's easy to get distracted by the power wheel when you aren't getting the results that you need and your response was perfect.

Another thing that I know that has hurt me is playing with too many types of bullets at one time. The variables of ballistics, air pressures, tethered vs. non-tethered, distance, scope power, etc. have made me go in circles. Don't get me wrong, I like the challenge but at the same time I don't like wasting money and time just lobbing stuff at the wall to see if it sticks. I like to base my experimentation on at least a little bit of fact or knowledge.

My new Air Venturi compressor is up and running so tethering now is not a problem as I can fill as often as I want 20' from my shooting bench!  :D  After I resolve my scope issue and stop hitting the dirt at 30 yards I will start sending you some chrony info/groups etc.

SteveO gave me some sage advice too; find a projectile and stick to it. It's so easy with the big bore slug launchers to get caught up in trying all of the different bullets, but in reality for a newbie it's just information overload.

Turkey season opens in a few weeks and I can't wait to add some more meat to my freezer. Should go well with the crab opener next weekend!  ;)

I'll keep this short...

I purposely asked some specific questions to avoid random musing.

I've said it before, I don't give two $#!T's that it's loud. I've got a $5.00 pair of ear muffs if it bothers me. Accuracy is my goal.

'the right bullet and tinkering with it will tighten groups'...no shit?

We know it's not as good as the WAR Cobra, you've made that clear.


How is any of this relevant? There are Texan owners who frequent here with some amazing pieces that have been modded out to the max and they achieved fantastic results. Some simple suggestions for a stock Texan would be second nature for them because they actually OWN one or know the Airforce platform enough to offer fact-based advice.

I'm hoping to try to make some improvements on my .308 Texan. Some things that would like to know are really basic and apply to the general principles of airgun mechanics. Here are some things that I'm just a little confused on. If you have input, the more dumbed-down, the better  ;D

The Texan self regulates but has a tuning wheel. The instructions were vague as how to use this. I don't know which way is "more" and which is "less".


Should I change it at all? Right now I'm somewhat in the middle.


I shoot a lot of different ammo from 44 gr. round ball to 198 gr. slug. If I used the wheel properly would it markedly help accuracy and/or air usage?


I'm seriously considering a shroud. While the noise doesn't bother me, it couldn't hurt to quiet it down since I hunt on the property I recreationally shoot. However, accuracy is more important. I know R&L has a shroud, but would a carbon fiber sleeve possibly be better for performance?


Would a muzzle brake have any use on a Texan, or is it just a way to pimp out the gun for cosmetic's sake? 


Considering a Maddog stock at some point...has anyone used that and if so does it make a difference?

So here's story: I bought the .308 Texan w/Hawke scope combo. I have had moments of glory, but changing bullet sizes, power on the scope, air pressures, etc. has been a steep learning curve. I might find a sweet zone with 118 gr. and then switch to something larger and tinker with adjustments on the scope but I never seem to be able to get it right. Granted, it seems the .308 Texan isn't exactly a tack driver out of the box but I've seen what it can do. I had to remove the scope and place it back on again using the picatinny adapters. Everything looks perfect and not tweaked in any way.

When I went out today to shoot, I was kicking up dust about 3' low at fifty yards. For whatever reason the gun never shoot the same twice and I was using some new ammo so I thought it may need some adjusting. I maxed out going up and I'm still 1.5' low at 40 yards. I can't see anything wrong with the angle/mounting...I'm kind of lost. I'm used to old school fixed 4's and 3x9's on center fire rifles without as many bells and whistles and way more room for error due to trajectory.

Before I start stripping this down and trying to assess where my issue is, I would welcome any advice. I could just be overlooking something easy.

What kind of a house is that for a dairy farmer? I'm used to peeling paint, a million flies, fifteen pairs of rubber boots by the door, piles of bailing twine for landscape, at least 5 stinky dogs laying around, and a dead calf next to the dumpster.

I have to get out of California. Congrats on the Cobra!

lol!!!!  ;D ;D ;D

What did you expect??? You keep feeding them! Since I live rural I'm always fighting the skunk battle. I have 6 bottles of hydrogen pyroxide and equal boxes of baking soda for the dog. He got it three times in a month last year because I had one under the house and he kept running into it.

Take one for the team and shoot that stink weasel. Man up! I mean really, how bad could it really be?  ;D ;D ;D
