I finally got around to it this weekend. I have some 545 data.. I put together on the 5.45X39 reloading project... In the Bulgarian 74 All rounds chambered, fired and ejected fine, and I had no cases, split or fail in any way.. they did bulge at the case head as expected.. I lost a few in the weeds/dirt.. I'll reload them again and see how they fair..I used wolf primers which seemed a bit soft. I'll replace them with CCI on later testing.. I'm very happy with the results..
