I have a Remington 760, 30-06 that shoots quite well (1" groups at 100 yds, quite often) when single loaded. However, when shells are cycled throught the magazine the group opens up to double or triple the size. After looking at unfired bullets after cycling them through the magazine and chamber, I discovered that the noze of the bullets are damaged as they enter the chamber. Some lead is scraped off leaving a flat spot about 1/8" wide and over that long on the edge of the bullet noze. I suspected it was due to the magazine not holding them proberly and bought a new magazine and the same thing happens. I am shooting 150gr soft points winchester factory loads. Has anyone else experienced this? Any suggestions to correct the problem would be greatly appreciated.
