I have .44 mag revolvers and prefer to be able to use the same ammo in rifle and pistol, so the best compromise I found for my guns was .432” bullets. I used powder coated 429421 and 429244 (basically the same except with a gas check). They all work well but I’ve found that for my rifle the gas checked bullets are more accurate, even with lighter loads.
That’s just what works best with my rifle; I understand yours is different with different rifling.
