I picked up a 1903 last February and have tried several loads including MD's H4831 load. My stutzen has shot most everything I've tried in it well, including some old Norma 139 gr factory loads I ran across. I'm using them up right now, but will go with MD's load, 160 gr Hornady RNs and 40 gr of H4831, as soon as they're gone. Can't help it....I'm just a traditional sorta guy! The M-S's reputation was made before WWI with 160 gr RNs, and that's what I will use in it.
I have those same factory loads. They shoot OK and are a good source of brass and since I have a couple hundred 160's and IMR 4350 that I use in a Rem 6mm, thought I would go that route
