The factory new 180 FMJ rounds I got really were not very impressive grouping out of the Sig 220-10.

I tried a variety of 165 plated Berrys and had a paucity of recipes. They sent me some ideas & I honed in on a load that seems about right for bowling pins:

Haven't chronoed it yet but all other indicators PLUS careful study of the data they suggested, gives me hope this recipe is suitable: *NOTE* disclaimer & any use/etc is NOT advised/suggested/even talked about....

Thinking 165/~1100fps/Universal Clays.

Gives pleasant reliable 2.5" group from the bench at 30'.....about pin table distance.
