Even though I've been hunting my whole life (I'm 53), I've never gotten into modifying/building guns. I am familiar with guns though.

I pulled out my Lyman manual. It shows a max COL of 2.775 for the .257 Roberts with 100 and 117 grain bullets. The Lyman manual shows a max COL of 2.820 for the .308.

I noticed this before my post, but wanted to see if anyone else picked up on this also.

Thanks for the reply, Cycler.
