I have had good luck with the 285 Priv bullets and at 50 meters it places a upper and lower pair set in about 2 1/2 tall by 2 inches wide the lower barrel shoot just below the point of aim and the upper set is about 2 inchers higher I have not ran this load thru a graft yet, I got the load from this web site when I made up testing loads I started with load listed and the load shot just a little low so I started up .5 grains at a time when I got 67 the upper barrel placed two shot on top of each other right at the point of aim and the lower barrel was about two inches lower and the lower barrel shot a group about 1 3/8 apart just to the right of point of aim and I quit, I was going to put a scope on this gun but I want to make hunting fun again so it will just me and my old eyes I may have to get closer but that what hunting is about.
