Having scope issues due to inexperience
« on: October 25, 2017, 11:59:10 AM »
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.

A photo is worth a thousand words!

If it were mine....

I do not use scope mounting adapters, unless there is NO OTHER WAY to mount one. Which means is, I would have used an 11 mm ring set. All too often, the adapters are Chinese made. Some of their stuff is good, others, not so good.

And, if you're running out of scope adjustment, this first thing to look at are the mounts. Oh! If you buy a set of correct rings, make sure you recenter the reticle before you re-sight in the Texan.

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.

I have experience sighting in a .58 Quackenbush Rifle.  I initially got 2 shots out of the rifle. 2nd shot dumped all the air. Now I get a max of 3 shots out of this rifle, and each shot past the first one drops way, way down.  It was a bear trying to figure this beast out.


My fix was to tether the rifle with a small carbon fiber bottle and regulator, and then get the rifle sighted in.

Oh. For Ammo all I have now are .58 round balls. I suppose you could note the scope settings, and then what it takes to zero in new ammo, and keep notes. This way you can redial in your settings, and at least be in the ball park. I do need to cast some hollow points at some point.  Then I'll be in the same boat.

So you were using the Picatinny before, or you just added it?
If just added you can try switching end for end if possible.
If gun just started shooting low, and all other things the same, I would look for a leak. Maybe at the breech or transfer port, maybe chrono to see your fps.
Another thing, did you bend the scope tube when mounting it? Chineesium parts aren't always in alignment.
OR, the scope went kaput.
A little something I've picked up, the scope is designed to operate at the centered position(or real close to it), not way up, down or side to side. Shiming the scope in the mounts is usually the way to go, though Burris has rings that are adjustable.
Buncha BB guns that I don't get to shoot as much as I like.

Hi Kevin,
                I've had to shim Scopes in the past due to lack of Breech angle. I use pieces of business cards.  Can I borrow some ammo is up your way in Santa Rosa.  Invite John and his dog over for lunch.  Might just save you some grief.

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.

How did you do on opening? We skipped opening this year as last year we almost took out a kayaker leaving out of Bodega Harbor and my buddy didn't want to have to go through that again. Shook him up pretty good.  USCG should have been patrolling the channel AFAIC.
We're going out starting this coming Sunday. Off time we'll try for some Cabezon or lings then pull traps, rebait and come back the next day, then repeat almost daily for a few weeks providing the ocean and wind cooperates. Missed the salmon run as his boat was in Puget Sound at the time.

I hate openers. Launch ramps are insane, then there are those folks in tiny boats in rough seas, and dipsticks who use Clorox bottles for floats and floating line on their pots set in the channel. Ugh

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.

We are about halfway between Bodega and Tomales, out a couple miles, our lines are over 200 feet so we try to keep under 180'. There are a couple nice Stainless steel traps we lost last year that went past 200+ feet, Nautical charts are only so accurate, ha ha.

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.
