[QUOTE="J E Custom, post: 1420997, member: 2736"] I Don't understand why it wont get more velocity with a 168. I am a bit on the conservative side and never load high pressure loads (Anymore) and My 7mm RUM exceeds 3300 easy with the 168. Check your load length and make sure you are using all of the freebore (The rums Need It to keep pressures under control and velocities high). Factory loads should be around 3200+. The 7mm ultra should be 10 to 12% faster than the 7 STW which has no problem with 3150 with the 168 grain bullets so that's why I was wondering about the velocity. I would also worry about the chronographs accuracy if you are pushing the bullets to there limits as you stated. If you are gust tired of the big RUM the only thing you will have to change is the barrel, and any Mag face cartridge will work with out any Other work. With the action length, the 7 STW would be a good choice for a rebarrel without giving up to much power. J E CUSTOM [/QUOTE]
