Yoder409,
I asked myself the same question regarding the performance of the STW and RUM from a 26" barrel. Took two rem 7 mag takeoffs and rechambered them. The 7 RUM beat the 7 STW by 50 fps using RL-22 and a 140 nos bt. IMO the 7 RUM needs at least a 28" or longer tube or you might as well stay with a STW.
