[QUOTE="nicholasjohn, post: 1971224, member: 109113"] Me, too - thanks for bringing it up and shaking a few new ideas out of the bushes. Another thing I'd like to point out here is that there are also variables unrelated to the load that can come into play at the shooting bench. I grew up with a guy who had a marlin 30-30 that would shoot groups that you wouldn't believe.
