point of aim with 38 spl snubby reloads
I've got 2 different reloads I use with my snubby 38 spl. First is a 125 grn Hornady xtp with w231. My gun groups these best with about 4.8 grains of w231. At 7 yards it creates about 1.5" to 2" groups.
The other load is a wadcutter, I can't remember the weight right now, I've got a box of 500 of them I've been burning through. But with about 3.0 grns of w231 it groups even better. 7 yard groups of 1" not bad for a snub.
Here's my question, the xtp's group well but hit about 2" left. The wadcutters hit dead-nuts on the bullseye. Why does this happen and is there a way to manipulate this through powder and bullet choices or reloading tricks of some sort?
Thanks in advance for any help.
