[QUOTE="DaveB, post: 5600509, member: 5958"] Nope. Following DA's mantra 1. Get the FPS you want 2. Modify length to achieve accuracy. For example, Our 243 Rem 700 ADL has a very long throat and modifying COL is easy to get inside MOA. If I set the bullet at SAAMI specs no accuracy (1.6 inch groups is not accurate) Matter of fact, just my own bias, I do not like long jumps and .030 is long. I try to get under .010 Long jumps is where you will get flyers (my bias). Most of the time the reason is inconsistent neck pressure so the bullet leaves the brass ever so slightly angled before becoming completely engaged in lands. ever notice how Mr. Big jams some rounds into the rifling? He doesn't do that because he can't figure out .007. [/QUOTE]
