[QUOTE="VLD Pilot, post: 2086173, member: 103947"] Well at 2900 and roughly 1000' elevation with an 8 twist barrel, you'd be right at bullet stability. 1.5 is your number. Guessing your 257 Wby mag will push that bullet closer to 3300 in at least a 24" barrel. It becomes 1.56 at 3300 fps. Altitude is your friend unless you speed up the barrel twist [/QUOTE]
