A good day shooting leaves me with some serious ladder test questions.

[QUOTE="royinidaho, post: 98956, member: 2011"] [b]Re: A good day shooting leaves me with some serious ladder test questi[/b] Which choke tube are you using? [img]/ubbthreads/images/graemlins/grin.gif[/img] [img]/ubbthreads/images/graemlins/grin.gif[/img] I'm thinkin! I'm Thinkin! How are you holding the rifle as in shoulder pressure, hand on forearm? That is, are you pulling in snugly into your shoulder with your trigger hand with your other hand on the sand bag? The reason I ask is that when my bbl was "barely" floated I was pulling it down against the stock sometimes when shooting off of pedestal rest. Then I got my handy dandy inletting tool and hawged things out so now you could drive a humvee in there. Check the free float while at the shooting bench. You get in your shooting position get your buddy to run a business card all the way to the recoil lug. If any resistance at all, consider some work on it. My standard for free floating is 5-1s together all the way to the recoil lug. Depending on the rifle I some times fold the 5 1s long ways. I've found that a good solid hold into the shoulder, the other hand squeezing the sand/beanie bag and letting the muzzle do whatever it wishes has been best for me. It also more closely duplicates conditions when shooting prone from bipod. You're not using REM 9 1/2 Primers, are you? I'd consider starting the test @ your #10 load and go up from there. In my Win. which seems to be a bit unusual as I can approach RUM velocities I got the following results with REM Cases and 4831sc: 71.5 gr = 2596 74.7 gr = 2788 Mine didn't like SC as much as it liked some other powders. Also, 20 shots in less that say 30 minutes @ 40 degrees temp. your bbl should have been pretty darn warm. Remember it will be warmer on the inside than on the outside. I'd consider shooting it, removing the empty, pointing it in the direction of the wind, leave the bolt open, then walk down to the target, kick some dirt/sand/snow/etc, then come back and shoot the next shot. I'm a bit confuxed regarding the relationship between trigger pull and traveling across country? [pull is a light 3.5 to 4 lbs (it will be used while traveling cross country sometimes). I wouldn't switch powders, but may consider switching primers, unless you're using Feds, until the randomness is removed and more consistency is achieved. Then consider changing powder if you think you need to. Another thought. Stand the rifle on the recoil pad. With screw driver in one hand and your other hand (dail indicator works better but your hand will be pretty sensitive) loosely holding the rifle around the barrel and fore end tip, loosen and tighten the receiver screws in different combinations. If you feel any movement or hear the stock squeeking as the action moves, then you may wish to revisit the bedding. I'm not sure who I'm talking to, thus may have covered some stuff that you already have considered. Hey, just trying to help. Good shootin' [/QUOTE]
