For reasons unknown to me, 46 gr. 3031 and a 180 gr. PSP do extremely well in my 4 30-06 rifles. I had built up that load for a pre-war Win. Mod. 70, and it grouped under an inch. So, I tried it in a Savage 116 stainless, a Mauser 3000 and Mannlicher-Schoenaur GK....and all groups were under an inch. Again....there are probably "better" loads.
But I have been happy with this one.
