My best load for those trappers is 35grn of LVR pushing a 160 ftx @ 2130 fps. If you want to check that rifles accuracy, I would suggest making very sure there is no copper or lead fouling in the barrel as I have found lots of these rifles with enough build up inside them to affect the accuracy. If that is all sparkly then remove the barrel bands, mag tube and the forearm. Try grouping it supporting it under the front of the reciever. I find this gives the best groupings, then you know what that rifle is capable of. I have trappers that will shoot 3/4"moa and I also have trappers that won't do any better then 2.5moa.
