I have a Sig P250 in .45 acp. I am reloading 200 grain lead SWC commercial bullets and also my cast bullets in Lee 200 grain SWC. I have some problems with feeding but mostly extraction. The case will start extracting and then the base of the fired cartridge will catch on the rim or portion of the bullet shoulder of the first out shell in the magazine. The extractor will turn loose of the spent case and continue rearward but will not go far enough to pick up new shell. Has anyone reloaded for this pistol or had experience with different shells. I am thinking of trying round nose cast but a pistol of this quality should handle those SWCs Ok. I have tried harder/softer crimps and different bullet seating depths. Any advice appreciated.
