My 442 seems to like 125grn jhp.....I carry 158grn Buffalo Bore standard pressure in my M36 and they shoot great, no so much in the 442.

I really like the BBore but it just doesn't group as well in the Airweight. Tends to shoot a bit high and the group opens up....same with Rem 158grn LHP.

125grn Win+p sjhp (white box) groups great and is dead center at 10yds
in the 442....maybe not the best performing round but can't argue with the accuracy.
