Yep,
The LEE roll crimp is your friend. Especially if you intend to shoot at any sort of extended range. I have not fiddled with these loads, but have put literally thousands of .44 mags downrange and the roll crimp allows the pressure to build a little more evenly in the case. The result is better accuracy at longer ranges. You might not notice it at 25 yards, but at 250 yards you certainly can.
Plus if you are shooting truly heavy loads, you greatly lessen the risk of bullets pulling out with recoil and jamming up the gun.
These .44 Russians also make a Model 329 Scandium Smith truly fun to shoot, which "FUN" and "Model 329 Scandium S&W" are rarely used in the same sentence.
