HI everyone, I have been loading 45 ACP with a lee 451-230-1r cast mould with # 2 alloy, 4 grns of HTG and an OAL of 1.265. This has been working well in all my 45's ie colt mod.70 high point pistol and carbine. I bought a new XDM 5.25 bi tone and am having problems with the OAL. It seems the bullet is not seated deep enough to allow the slide to close properly and extraction is difficult if not impossible when cycled by hand. Does anyone think I would have pressure problems if I shortened the OAL to 1.240. I loaded a couple of dummy test rounds and they seem to be cycling well at that length,TIA Chuck.
