Thread: 7mm PRC Factory Hornady ammo issue

I shot a bunch of 175 ELDX over 2225 yesterday doing seating depths, below book max charge & experienced the same thing as the first lot of development i did with RL26. Every now and then a stiff bolt lift & stamped/swiped brass, sometimes last shot on a string sometimes first, no particular pattern. Primers all look the same & was all shot across the chronograph & the "hot" loads went no faster than the others. Clearly cant be heat related as sometimes it would be the first shot that would do it after a 10 min cool down, id follow up with 2 more straight away to complete the group & they would be the same speed but no stamp/swipe.

I think all you can really do is either run really slow/soft loads, or if your trying to run it fast/up close to max just throw out the bad brass & eventually you will end up with stuff thats ok.

This seems to be a common problem with the Hornady brass.
I get the odd stamping with mine I haven't had an issue with blowing primers in factory yet.
I'm not doing too much load development till I get some decent brass.
