Hello I’m also new member, I bought rem. 300 rum Tupperware stock recoil was stout to say the least but the barrel jump was terrible, Vias break and a quality butt pad made it very comfortable. Since then pulled action out and built custom rifle around it but that’s another story good luck!
There is a good LR school in Colville Wa. run by a former marine scout sniper named Carl Taylor I think they shoot out to 1200 yds also has motion targets on tracts at 600 yds
