I have a Marlin 1894 .44 Mag, made in 1970, and am having issues with the 240 gr. bullet from the Lyman 429667 mold.

I tried a few where I crimped on the crimp groove, and it gave me the suggested OAL listed for this particular mold in the Lyman Cast Bullet Handbook. It jammed something horrible. I had to take the rifle apart to free the bullet. Next I shortened the OAL to a standard 1.610" which had me crimping in the shoulder above the crimp groove. For the most part it will cycle fine as long as I only put two bullets in the tube. If I go to three it jams up really bad.

This particular mold seems to be popular, but I'm curious how short it's being loaded to work properly. If I keep going shorter in hopes of getting it to cycle properly I'm wondering if there will be any pressure spikes.

Opinions, thoughts, suggestions, musings, etc. and most welcome.
