Re: Extreme spread / Standard Deviation

Another thought...
You say that getting the action out of the stock is a chore. It's possible that your recoil lug isn't doing all of the work. Your magizine could be (inconsistantly) absorbing some of the recoil which could induce vertical stringing.

    Actually, that has been suggested by a few of the locals at the range. Someone asked if it was pillar-bedded, and I didn't know, so I went home to take it out of the stock, as it had been a while. Takes me 5-10 minutes to get the thing out of the stock, *after* the screws are removed. And, no, it's not pillar bedded. The barrel is free-floated, w/ just a dab of bedding material about 1" in front of the recoil lug. It's getting to the point that it may be due for a pillar bedding job this summer, btwn rock chuck in the spring, and my (hopeful) trip back to western Nebraska in August or so.

    Thanks,

    Monte

    I think he also has a problem with the chronagraph not reading consistant.

    Just a thought.
