I have used the 200 Partition over R22 with great results. This was in a 24" bbl Mod 700. I am starting over with a Mod 700 Mountain rifle and its 22"bbl. Before I work up some loads, has anyone found a good recipe for this kind of set up ( 22", R22, standard or mag primer?) I have, fortunately, a good supply of H4831SC, H4350, Big Game as other potential powders. I have only used 4831 and 4350 in the past for 180's, but that was in longer barreled rifles. I'd appreciate any input, thanks.
