Cheap test for you:
Get 5 , 180 grain factory loads
Get 5 , 150 grain factory loads

What group shot better @ 100 yards?

You need a reference point to start with. Before you reload anything.

I shot 180's in my old 03-A3 that I rebuilt years ago. It just happend to like 180 rem bronze Points (no longer available) and H-4831, CCI Mag primers

It's possible that the two-groove barrel won't grip the lighter bullets (Shorter) well enough. The 180s, being longer, grip the two-groove barrel better with the faster twist(1 in 10).

Just my 2 cents....
