i just purchased and started using a hornady ap press (upgraded from lee classic) i reloaded 100 rds of 230 gr Hornady HAP using a 5.2 gn charge and an oal of 1.23. 96 of the rounds shot great with awesome groups, but 2 of the rounds when fired did not exit the barrel they only went down about half of an inch and i had to push them back through the barrel. now the other 2 rounds became lodged in the chamber and would not allow the cartridge to be ejected i had to again push the bullet out of the rifling before the round could be extracted. I am assuming that this happened because the rounds were not properly crimped causing a loss of pressure behind the bullet or the brass was not pushed up far enough into the resizing die.i have never had a problem like this using my other press in which i have loaded hundreds of rounds with. any insight on this would be greatly appreciated.
