Recoil Rob, I have a box of 150 Gr Remingtons also. I don't know how they shoot. No 150 gr jacketed .348's are made today to experiment with but I'm sure they are fine for deer. The normal weight is 200grs. Cartridge collectors may be more interested in the ammo than hunters. I have a small supply of Win silvertips that I use and when they are gone it will be the Hornaday 200's in reloads. I've heard that 71's generally shoot 6" groups and the previous one I owned shot just that. My long tang shoots good.
