Big bore day with Steveoh
« on: July 29, 2018, 05:57:28 PM »
Had a great time as always meeting up with Steve and throwing (a lot of) lead. Great to see Steve's DAQ .458 back in action. I love hearing Steve's giggle when a plan comes together. It was also cool to see the .45 bonging away with iron sites. Not many guns have them and in this shooter's eyes they are under used for sub-100 yard big bores. Paper is one thing, game is another. Iron vs. scope - a fun topic for discussion some time.

I was a one trick pony with just my Texan. Sort of a recon day; two different ammo types, two different rest types, and with muzzle break and without muzzle break.

I was not tethered during any of this shooting. I filled after every shot and was at 2850 to 3000 for every shot. I know that's not exact and could effect grouping so that's why I noted it. Honestly, I was waiting for my tank pressure to drop down from fills so that I can 'run open' but it just didn't get there. Filled to 4000 prior to leaving but next time I'll fill to 3500 so I have more tether time.

Basic results were this:

I didn't shoot until I got perfect groups; I just took a couple of practice shots and got to it. 118 cast and 128 swaged were very close in accuracy. 100 yard groups were about the same.  3 shot groups at 100 yards were consistently 2.5" - 3". Once in a while I would get that magical 1.25" to 1.75" group but that was the exception. A pattern that was subtle but existent is that the swaged ammo would often have groups with two touching and then one 'flier' out at 3". The cast would be consistent with a random pattern; high, low, left, right, but still tight. I'm wondering if the cast is more forgiving on air pressure but when the swaged hits that sweet spot it shines better? Just a thought. At 200 yards the results are slightly better for the cast. I posted the pics below of the 200 yard groups. Chrony was at 927 on the 118 cast and 901 on 128 swaged (averages). With both slugs I had two separate groups where I shot sub 4" groups of five at 200 yards, but I didn't photograph it (long walk and it was getting hot)  Again, this was about posting an overall average and not focusing on and glorifying a one-off perfect group.


As far as rests, I was using a table/lead sled and also the Born Wild Shooting Chair. There wasn't marked difference but if I had to lean towards one or the other I would go with the BWSC (somewhat biased, but the proof's on the paper)  The Texan's recoil allowed for a smoother follow through on the BWSC. The rigidity of the sled wasn't as smooth and it seemed like gun didn't 'float' during the shot (for lack of a better term). But results were similar with both. All of the 300 yard shots were with the BWSC since I just threw it in the truck and drove back a hundred yards.

5 shot groups are right around 10" at 300 with the 118 gr. Did not shoot the 128's because I was running out of them and the distance requires a lighter slug. Nothing spectacular but consistent. Fun just getting on the paper every shot at that distance with no problem. I put two shots through the same hole which really cool (and insanely lucky, but that's neither here nor there! lol) I should also note that my holdover is off of the main reticles/dots and into the duplex. So I'm basically holding off of the target and doing the 'aim at that blade of grass' trick. Really need that Cold Shot scope base. There was a little wind but not bad. Interesting in that wind is not really a factor at 200 yards but it's a big factor at 300 for the .308 Texan. 1" or 2" at 200 translates into about 1.5' - 3' at 300. This has been the norm for me shooting in a crosswind. The slug bucks the wind really well for 175 to 200 yards but then it starts to lose it fast.

The most interesting thing might have been the muzzle break. The difference with and without it was amazing. Like 'WOW!' amazing. The recoil is vastly reduced and I'm actually able to stay on target through the scope and see impacts. I've never removed it in the middle of a shooting session and I was shocked. I went from being close to being scope bit (my own fault) to really watching it all. I encourage you big bore guys to consider one these if you feel recoil effects your shooting enjoyment or accuracy in a negative way. I knew it worked good on my Remington .308 but I had no idea it was that effective on the Texan. Accuracy was either not affected or slightly enhanced by the mb. It's not that I can't 'take' the recoil, but I don't relish it and if I can reduce it I will. And with that long barrel I think it makes a difference in the follow through. I'm a believer.

Heifers kept interrupting our shoot, but we still got it done. We both had our fill, and after the cows invaded the range for like the fourth time we just conceded. Damn, I love this stuff.

Thank you Kevin for another awesome day of shooting. You are such a generous fellow. I show up late and you have all the targets set up, and the cows rounded up, sort of.  (Damn the Race Day traffic on Hwy 37!)

As usual I brought too much stuff. DAQ .458 LA Outlaw, DAQ .58 Outlaw Short Rifle, San Yang 909s, DAQ.58 Pistol and my trusty Marauder. Last two AirGuns stayed in their soft cases.

The DAQ .458 apparently had a jinx on it. When I finally got it, the stock got mangled in shipping. Sent to Dennis to repair.

Shot it at the range one day, then another day at a Kevin Airgun Fest, and I had a bolt blowback, which sheered the bolt.  I thought I was careful, but I take blame for not seating the bolt handle. Cost me $20 in parts and got it back together for another another shoot and first shot I had another blowback that also sheered the bolt. No way the bolt wasn’t closed. This time I threaded some stainless steel 1/4” rod and got a 1” steelball for the handle. I figured the extra weight would help keep the bolt in place. I tested that theory today. Dennis says that there's no way a bolt will popup and back on it's own, and it has a ball bearing detent to tell when it's properly seated. I remain unconvinced either way. At any rate, the rifle has my full attention, and respect when loading, cocking, and shooting.

Today, I had no mishaps, and the DAQ behaved. I shot video for most of my .458 shots, just in case I had a mishap. Looking at those videos, I found one, where I see my right hand involuntary leave the stock in a flinch as the slug went down range. In this case I pulled my hand back. I don't remember doing it, and only have the video as proof. I suppose there is a chance that I might have flinched, and had my hand involuntarily knock the bolt out of being seated. But do not have video of either instance.

I really had an awesome time whacking the gongs at 50,100 and even 200 yards.

The .458 Outlaw has a stock, as recommended by Dennis, rating of 3000 psi. Folks like Mr. Hollowpoint, and Eric Henderson run their DAQs at a bit higher pressure. They run strings until they get a max FPS for any given weight bullet. I told Dennis that this .458 had been shot at 3600-3700 psi by Eric, and he said it was not a big deal, and that it would not cause any issues with the rifle.  I took one home case bullet of 220grains and took the gun up to 3700 psi for an FPS of 994.6 and an FPE of 482.78. That's a bit hot, and after this reduced PSI to 3600. At 3600 psi this pure lead bullet punched a hole through one side of a cast iron rotor off my Dodge Dakota.  I giggled when that bullet smacked the rotor.  Paper is ok, but hitting steel makes me giddy. 

I have a couple new .458 molds I need to break in, because I don't think I've quite found the right bullet this gun loves for 50-100yards.

One thing I chewed on yesterday was the fact that I'm relying on a tiny little gauge on the Airhog that I've already replaced once due to lack of accuracy. I'm thinking I need a much better gauge because a 50 psi drop can make a substantial difference of POI. At least I think so. I'm also chewing on an expensive regulated valve for the big tank. I think to get maximum accuracy out of these DAQs on the first shot, you need to be able to make that fill consistent. Yes, I am jealous of the accuracy I've seen Kevin get out of his Texan .308. Makes me think a Texan .308 or .257 might be my next airgun. Maybe.

After I ran the big tank down I switched to the .58 Short Rifle and had tons of fun with it. I've pretty much decided that the .58 rifle and pistol just like roundballs and that I should stop screwing around wasting pounds of lead trying other bullets they just don't like. But, I have found that increasing that PSI to 3400-3500 on the .58 DAQS I am getting better accuracy. Go figure.

Then I switched to the 909s and finally pulled off the bug buster since it was flinging lead all over the place. Iron sights were fun! I might just leave a scope off.  The 909s appears to love round balls also, and it's standby EPP-UG (El Paso Pete Ultra Gamer). https://www.gatewaytoairguns.org/GTA/index.php?topic=29646.0

Awesome day! Will post images and some video tomorrow. VIDEO COMING!
Thanks Kevin!

I guess what you both need is one of the 12 volt compressors (trusting you hook them up correctly).

If I would have been there, I too would have been a one horse buggy. While I have several airguns, the WAR Cobra is so much fun to shoot, the others languish and befallen to dust! One of these days....

I have an Omega compressor. If you're a fellow Guild member, and you pass through Roswell, NM, I'll fill your portable tank as a courtesy.

We talked about this. The DAQs suck air like crazy. I'm talking going from 3,600 psi on first shot down to 2,000 psi. I can get a second shot, but then I have to fill from 400 psi back up. It's time consuming. For hunting a single shot with one followup is reasonable. But when busting steel, it gets old.

By the time I got down to the 909s, it consumed much less air, for less power, but it was actually a bit more fun since it wasn't kicking like a mule, and I wasn't flinching, and I could get four shots before refilling. I think in the end, I'll probably cut a coil or two off the .458 DAQ hammer spring and see if I can't reduce the air consumption. I doubt I'll lose much power.

But I have to say having a portable 12v compressor will be a game changer.
