For the loads used, what primer are you using? What other bullets have you tried? Have you tried different bullet seating depths?
For the LRX 168gr, how do they look for the hole on the traget? Are they nice and round or oblonge?
How long do you wait between shots? I usually wait about 1 minute with the one STW, as it has a heavy barrel. For my second STW, I will only do a 3 shot group due to it has a lighter barrel on it.
Do you change the point of contact for the front rest?
How is your breathing when you pull the trigger?
How about the trigger, where is the poundage set?
Just some other things to think about.
-Break in: I shot 1 and cleaned for 10. Shot 3 and cleaned for the next 30.
-primers: Using CCI mag rifle, going to try Federal mag rifle.
-cleaning: scrubbing with Hoppes 9 then patching 'til clean, then scrubbing with either Hollands witches brew or CR10 and patching 'til clean, 1 patch with alcohol, then an oil patch.
-Other bullets: I've tried 160 Barnes TSX FB & Factory 160 Nosler AB
-Holes: They are ripping the paper slightly, leading me to believe they are key-holing somewhat, the TSX loads were perfect little holes but a crappy group.
-Rest: I am not changing the point of contact and my breathing seems controlled. To rule out human error I even shot off a lead-sled (Im not a fan of them) to assure it was a steady shot, same results. Had my buddy shoot off the bags, same result.
-Trigger: its a Jewell set at a nice crisp 2.5 lbs
-Time between shots: Im not waiting a particular time (prob atleast a min) after I see where I hit, jot down the chrono speed, reload, and find aim point. Its a #4 contour so not heavy, but doesn't seem to get very warm.
A big thing I forgot to mention was, McMillan screwed up the barrel channel of the stock where it wouldn't fit well. My smith had to inlet it some to free it up. Its now bedded and free floated up to 3" in front of the recoil lug. Next time I shoot I'm going to check the free float before each shot.
Thanks for the help so far. Any other thoughts with my answers above?
