Manuals list a 44 Rem Mag handgun as having a Max. Cart. Lenght of 1.610". I recently loaded some Oregon Trails Tru shot 310 gn WNFP and crimped in the cannelure came up with lenghts of 1.637 to 1.641. They seemed to fit OK in my Redhawk and I did not see any problems when fired. I loaded at 19.5 gr H110 which seems on the lighter side for these rounds. Am I being sloppy and unsafe or does listed Max lenght only apply to certain handguns? I think I remember reading somewhere that as long as the cartridge fits within the cylinder it is not too long.
What really is Maximum cartridge lenght?
