Every rifle has it's own personality, but my NewEnglander is very funny about what I feed it. Maxi-Hunters will not group out of it, but the Lee 320 grain REAL is a tack-driver. It also likes 350 grain .458 cast lead bullets in an MMP .50/.458 orange sabot. I just tried them a short time ago, and put the first 4 shots into one ragged hole at 50 yards, but of course I had to try shot #5. [:@]
