I would suggest starting out with 150gr of different types.

If you have a barrel under 24 inches there’s a chance you won’t get the 165 , 168 gr to group at all.

Mine will shoot nickel sized groups with 3 different 150 gr types.

Put any 168gr in it and it won’t group 5 inches at 75 yards.

I’ve got about 6 boxes of 168gr and don’t have a gun that will shoot them.
