What size arrows are you shooting? I try to shoot the lightest arrows that are safe for the bow. They keep changing stuff so fast anymore I’m probably behind again, but I think it’s 6 grains per inch, counting broadhead and fletching. If you were shooting 50 # you wouldn’t want to go under 300 grains total arrow weight. The lighter the arrow the more unforgiving the bow(larger groups). If you shoot well, no jerking etc. it wouldn’t matter. I think the lower the pounds you have your bow set, you need the lightest arrow you can shoot safely(for your bow) to get more faster, flatter shooting. Flatter shooting means easier range estimation. I can’t shoot the lightest arrows I can shoot in my bow because my group starts getting bigger.
Lot’s of people buy their arrows at Wally world and take what ever’s there and kill deer all the time, but if you want the best performance out of your bow I think going to an archery shop and talking to them and trying different arrows is the thing to do. It can get really technical and a turn off, but if you want the best performance match the arrows to your bow.
