I've loaded 175 grain Partitions for my 7mm Rem. Mag. since I bought it 10 years ago and they've shot fine. When I booked an elk hunt, the outfitter suggested I go to a 160 grain, so I did. The problem is that I've tried a couple different powders (IMR) and loads, but my gun just doesn't like them. I was wondering if anyone had any load combinations I could try? What about a different brand bullet? My gun is a Browning A Bolt with a 26 inch barrel.
