I'm wondering if anyone here, or anywhere on the net there are actual figures for .308's in relation to barrel length. I understand that at some point (and what point would that be?) you lose a certain amount of foot-pounds of energy for each inch of barrel you remove. But I'm more concerned with accuracy than energy, since I don't shoot past 300 yards anyway.
I'm wondering about accuracy at comparative distances. For instance, Remington makes a 700P with a 26" barrel. I'm wondering how the groups would be affected at say 100 and 300 yards, if you compared that gun side-by-side with the same gun, but after having the barrel cut down to 22", or 20", or 18"?
I suppose a more straight forward comparison might be the 26" model and the "LTR" - which has the 20" barrel - if anyone has any experience with that.
From another angle: I don't see a reason to go down to 16", but I'm wondering what is gained (other than ft.-lbs.) with every inch over 18"?
Also, do some bullet weights respond better to longer barrels?
