Long been a fan of the Argentine mauser (1891 variant) and it's cartridge the 7.65x53mm cartridge. I had my first one way back in 1963. I have two sportered ones with commercial sights and one carbine with the military sights. Thursday I took delivery of another 1891 rifle that had been reworked by one of the importers and had the barrel shortened,front sight relocat6ed and had the military stock somewhat modified. What I'm looking for is a cast bullet about180 grains weight with gas check. I have IMR 4759,Hogdon 4895,4227.2400,and a couple cans of Accurate 5744. Winchester standard primers and Hornady 150 and 174 grain jacketed bullets but this post is about cast bullets. Thanking you in advance for your help,suggestions and or comments.Frank
