[QUOTE="jmden, post: 166209, member: 1742"] You didn't mention the twist rate of your barrel. Even if it's a 10 twist, I would go right to the 240SMK and do not look back. I'm shooting that out of a stock 26" 10 twist with 104.5g US869 and I'm right at 3000fps. Getting several loadings on Rem brass. Only thing I do is turn off the high spots on the necks and make sure the flash hole is centered and not blocked. Last group I shot was at 880 yds and it was 3 1/2" and nearly centered on the target. 15MOA come up with a 275 yd zero. Pentrated 1/2 way through a 1/2" thick mild steel plate and pushed out the back 1/8" at 1/2 mile. That's a very hard long range combination to beat. Guys have found that with the 10 twist and the 300RUM they can get away with that bullet because of the 'extra' speed of the RUM spins it fast enough to stabilize it out to about 1500yds even though Sierra calls for a 9 twist. If you have an 8 or 9 twist that stabilizes the 265g RBBT Wildcat, work with that (prob. want some WC872) and don't look back. And, there's absolutely nothing wrong with a 'one bullet gun' as long as it shoots that bullet accurately. Dead is dead. [/QUOTE]
