I would say yes, if you are a very good shooter with your 642 and the recoil doesn't bother you. For me, it's wadcutters. I'd recommend trying both out side-by-side, and then make an honest assessment. I'm personally not confident enough in making good hits with my 442 loaded with +P ammo.
Clay that makes good sense. I've shot both the wadcutters and the gold dots. The Gold Dots are a bit sharper in recoil but for me, they are very manageable.
