hangunnr Posted August 8, 2009 Report Share Posted August 8, 2009 Got out last weekend for some informal long range steel plate shooting with a couple rifles. Ran several hundred rounds through my DPMS LR308 with little fanfare until this round was fired. On the shot I got a face full of powder, brass residue and hot gas. The follower in the magazine was pushed down and lodged sideways and the floorplate was set askew. In all the years I've been fudging around the shooting sports I've never seen a case failure like this one. The brass let go in what should of been the thickest part. The general consensus is that there was a flaw in the metalurgy of the brass. What's odd is that this is the second loading I've done of this case. Just goes to show that **it happens so it's better to have and not need safety glasses than to need and not have them. The visible erosion on the rim is pretty interesting. The inside of the floor plate of the magazine is speclkeled with brass particles. hangunnr Quote Link to comment Share on other sites More sharing options...
jokostel Posted August 9, 2009 Report Share Posted August 9, 2009 Not like it was over pressure or anything..... the primer still has radius, and no visible brass flow on the head. Just a bad case,imo..... simply a defective cartidge, that could have turned into a bad situation. Thankfully, it didn't. Quote Link to comment Share on other sites More sharing options...
Adjam5 Posted August 12, 2009 Report Share Posted August 12, 2009 Wow... That is a Lake City/Nato round also. I am surprised. That stuff is usually top of the line brass. Glad no one got hurt. Could the extractor have been a bit too aggressive? Quote Link to comment Share on other sites More sharing options...
Jeramie Posted August 12, 2009 Report Share Posted August 12, 2009 Ive heard of head seperation (after abusing brass) but that is crazy! Good thing you had glasses on! Quote Link to comment Share on other sites More sharing options...
hangunnr Posted August 13, 2009 Author Report Share Posted August 13, 2009 When I get the chance I'm gonna section the case to see what the inside looks like. hangunnr Quote Link to comment Share on other sites More sharing options...
