I was planning on shooting approx 375 gr arrows but put a few of my old 420 gr arrows thru my new bow and they are a much better grouping so I think I'm going back to heavy. FWIW I was shooting a 298 IBO PSE Nova before and w/ the 375 gr I was on a single pin out to 30 yards. Now I'm shooting a 330 IBO Empire and the heavier arrow just groups better.
381 grains. I'd normally like to shoot a heavier arrow but these fly great and still shot through the upper leg bone on a deer last fall.
