I have been thinking about getting another rifle built and I was looking at my manuals. I looked at the 7 STW and the 7 RUM. I already have a 280 AI with a 24 barrel that I get 2990 with a 160 accubond. I just can't see why people for crazy over them. I run 59 grains of RL-19 in my 280 AI with no pressure signs. The 7 STW takes more powder to get the same speeds anywhere from 66 to 74 grains. The 7 RUM I wont even go in to that powder hog. It will get 200FPS faster, but at almost 30 more grains if powder. For those numbers I will have to stick with my 280 AI. Modest recoil and I get more out of a pound of powder. My question is what is the appeal of the powder hogs?
