RE: rock chucker sepreme
I have never had a 7mmRUM, but had 3 300RUM's. But I like the STW. I don't know why, but I insisted on getting 160gr Accubonds shooting. Maybe because the factory federals shot them really well so I knew the gun could handle the bullet well. I tried H1000 with 1.5MOA average, tried 4831sc with no luck, but found 7828 75gr was awesome. Averages .75MOA also at 3100fps. So I am finished. I havn't tried anything else. I don't want to burn this one out like I did 2 RUM's. I got a gun (sako 75 stainless), that I like just about all the features, and will make a dandy moose gun. I have 140gr triple X and 160gr partions, but don't think I will be tryin them as long as the accubond performs well.
175gr aframes has so much sectional density, it should be a great elk bullet. I bet you could rip thru a shoulder no problem. I know the STW is no RUM, and you are probably blowin those numbers away. Sounds like you got a good gun. I think stumble has some real heaters for the STW.
