[QUOTE="mrultramag, post: 759585, member: 4467"] you sound like you want to build a 7 rum so might as well do it. you might find out what gunsmiths have worked alot with the 7 rum and see if there are any different configurations of throating it that can help extend the life of the throat. I'm not sure what options are available other than the factory style leade (freebore throat). I'm not talking about shortening the free bore but rather the angle of the leade and whatnot... something that may ease the erosion by the hot gases. Also might look into powder options and see if there is credibility that ball powders are easier on throats than coarse stick powders... US869?? Just some thoughts.. BTW I dont shoot long range but my 7 rum has approx 700 rds down the tube and still shoots well as far as groups at 100 from the bench. [/QUOTE]
