[QUOTE="esshup, post: 247715, member: 11101"] LV: Thanks. I see clearly now! Well, clearer anyway. :D So RPM IS a valid measurement (i.e. helping us figure out how to stabilize a bullet). Is there any rule of thumb on figuring out what rpm it takes to stabilize a certain bullet? I know what you are saying about the bullet torque. In shooting a 110g .25cal Accubond @ 3400 fps in my 10 1/2# Vanguard, the rifle will torque the left bipod leg up off the shooting bench a good 2". It doesn't have a brake on it. My .257 Weatherby that does have a brake doesn't do that, but the bullet is 130g and has less MV (3250 fps). That one is a MarkV and weighs less than the Vanguard. I'm unsure whether that is a function of the brake or just the bullet/MV. (on the MarkV) Both guns are 1:10 twist [/QUOTE]
