I've just been humbled and taught a valuable lesson by my Wesley. It said "Treat me like a kid,I'll shoot like a kid. Treat me like a man and I'll shoot like a man".
I started off with a couple different arrows to see what it liked. Around 575grains. 2-3" left on the average. Tried different arrows and the same outcome. Went up a little in weight and not much difference. So I said,I'll teach you. I loaded up a 160 grain snuffer(+ 15 grain lead),125 grain steel BH insert,and a 50 grain brass insert. 665 grain GT with(350 up front) Went out to the target and said"Now take that"! My bows response was-a bullseye!!! Next shot-1" right. 3rd shot-bullseye. Dropped back to 25 yards to see how much drop-2" drop but centered. I have some tinkering to do yet but looks like this one loves heavy arrows.
