Years ago when I shot the .44 I had different brands of brass and there was a lot of variation in length, so much that it was necessary to trim them to the same length as the shorter brass. The crimp needs to be uniform and heavy in the .44. Could shoot sub 2" at 50 yards on a good day but you gotta have good ammo. I was never able to make accurate light loads but the full magnum loads were super accurate.
