[QUOTE="Varmint Hunter, post: 322126, member: 313"] Very interesting. I thought that I was the only one who was experiencing this problem with my recently rebarreled 300RUM. I've got a 27" Broughton 5C with a minimum spec chamber. Handloaded (new) Federal brass ejects normally. Once fired brass reloaded with the same load needs to be tapped out with a cleaning rod. I am using Redding "S" type FL bushing dies, just pushing the shoulders back .001-.002". Swithching to a Forester match FL die did not resolve the problem. Switching to Rem brass gave the same results, OK for the first shot only. Reducing loads to 300WBY levels was one of the few ways to get the spent cases out of the chamber w/o difficulty. I didn't chamber this rifle in 300RUM so that I could only use 300WBY equivalent loads. One of the only ways I was able to mitigate the extraction problem was to swith to Hodgdon US869 powder. I assume that it produces less peak pressure. My accuracy load is 101.1gr 869 under a Berger 210 VLD that is loaded .020" off the rifling. My smith tells me that he has built many rifles using the same reamer without a single complaint from anyone else. He originally thought that it was an issue with the brass but that didn't pan out. I sure will be interested in the responses to this post. [/QUOTE]
