I have an M44,stainless, 8 3/8" and usually shoot .44 Spls for my practice sessions. I try to shoot at least 18 rounds from each position - standing, kneeling, sitting, prone, etc. all hunting positions I can think of or till I'm out of practice ammo. Then a cylinder full of my .44 mag hunting load. Right now that's the Winchester Supreme, 250 gr. Partition load.
