[QUOTE="James H, post: 211956, member: 5449"] As you increase powder capacity you reduce efficiency. The 7mm RUM offers less gain over the 7MM STW than the 7MM STW does over the 7MM RM. You will get a little more speed from the STW my experience is around 150fps over the Rem Mag or approx 100 yards difference, meaning the STW will be traveling the same speed as the Rem Mag about 100 yards further out. I really like the 7mm STW and think that it is an awesome cartridge but is is just over my comfort level for shooting at the bench(without a brake), whereas I can shoot the 7mm RM all day at the bench without it bothering me. For efficiency and performance it is hard to beat the 7mm RSAUM, I get a little over 3000fps with 180 Bergers in a 28" barrel, 3150 out of 162 Amaxes in a 30" barrel, and just over 3000 out of the 162 Amaxes in a 26" barrel. All my 7mm SAUM's are however custom chambers. James [/QUOTE]
