I am new to this forum,but read it quite often. I need help with my 454.srh. I don't know if it is my gun or my loads, but my hulls keep sticking in the chambers. I currently am shooting both cast&jacketed bullets. I need agood load for a 300 gr cast with either 2400 or 296. My gun loves a 300 cast with 27.5grs of 2400,about 2" at 50yrds, but my hulls have to be beaten out. I am using starline brass and cci 400 primers. Any help would be greatly appreciated. Also some good loads for 250, 300 gr xtp's. Thanks!!
