I bought a slightly used stainless Remington 700 bdl in 7mm SAUM last winter, I've got a habit of liking odd or less popular cartridges. I load my
.260 Rem with 120gr TTSX for deer and my .35 Whelen with 225gr TSX for moose so I figure my 7 SAUM will be my "in between, do it all" rifle. My plan is to load it with 150gr TTSX.
I have a bunch of 154gr Hornady IL on hand so I used those to give me an idea of which powder to use with the 150gr TTSX. So here are my results using RL19, RL22, H414, H4350 and H4831sc.
I think RL22 is going to be the winner.
