Trying to get a full power cast bullet load in the 120-130 grain bullet weight class. Ive got a 130 Seaco round nose mold and a 130 lachmiller spitzer mold. I cant seem to get either to run in my gun. Im casting them hard and powder coating. Ive tried seating at the recommended length for jacketed 120-130 grain bullets (that run fine) and have seated them out to the point the neck has problmes holding them. they all want to stove pipe. they start coming up out of the mag and hit the feed ramps and the bolt rides over the case. Now I have had good luck with the 155 lee. What the heck am I doing wrong? Is there a 120-130 cast bullet that runs a 100 percent in your gun at full power? Is pc coating drag causing me problems? Ive even bought p mags and bravo company mags that are specifically for the 300 bo. Any help be it molds seating dept ect would have welcome. What Id like is a cast bullet that shoots to about the same point of aim as 130 bts and 130 ssts. Gun is a 16 inch psa with a pistol length gas system. I runs jacketed perfectly.
