I've shot 1000+ rounds through my 12lrp and it had a few blown primers here and there with hornady match 140s. This is a old subject and been seen alot with hot loads and short cut throats,but my bolt face is eroding a bit and I finally got all my guages to check my coal.oal.etc and it seems to me my throat is short? I can see Mark's all the way around the ogive. But since I threaded the barrel for my recce 7 I don't think they are gonna warranty the known short throat issue on my rifle. Suggestions?
