I've been loading for my 6.5x55 for a while now and it's always shot reasonable or perfect groups with anything I put down it from 95g vmax to 160g factory ammo. I decided to try a couple of new bullets: Hornady 100g soft points and Sierra 120g Prohunter. I loaded a few different powder charges and various OAL. The pic is the best group I could get from 100g Hornady SP's. so bad I thought I had a problem with my rifle. I checked my other loads and they were perfect, along with he new loads I had made of the 120g Prohunters. I know some bullets don't shoot in some rifles but I thought that meant 2-3 inch groups at 100 yards....not 4-5 inches. Anyone else seen groups as bad as this with a particular bullet?
