I dont think its hard, you need the .17 funnel but other than that. same as anything.
Standard load is 24 grains of varget with cci br primer and 25 gr berger match .3's off the bench.
Im experimenting with woodchuck dens 27gr golds. same primer,powder but 24.4 gr (3915fps), shoots 5/8th inch group. So far Im not sold on them. Only shot 2 with it, so far but both exited. one was 140 and the other was 310 yards.
