I haven’t loaded much handgun ammo so kinda new at this. I loaded some 44 magnum and shot it through two different rifles with varying accuracy. They were all loaded with the same bullet, powder and primer. The brass was previously fired and I noticed when seating and crimping the bullets some would seem to start the crimping sooner than others. I’m assuming this would cause a tighter crimp. Does that affect accuracy? Can someone enlighten me please?

Thanks in advance
