300 RUM pressure?
While getting ready to teach a friend to reload for his 300 RUM I noticed that about half of his once fired brass had very visible extractor marks (brass had flowed into the round extractor pocket in the bolt face). 47 out of 100 piecies of brass were like this. Is this normal for this round? What kind of brass life are you guys getting with this round?
When I asked him if he had ever expierenced a stiff bolt with his rifle he had no idea what I was talking about. Rifle is factory 700. All brass is from factory Remington premier ammo.
Thanks in advance Rob
