Hey fellas, I just got a Jk traditions longbow, it's 58" and 46# @ 28. Love this little bow, so light and I really like the grip. I got some mfx classic 500 full length with the 75 grain insert and a 125 grain point. Shot and the arrow showed weak, ok so instead of cutting an arrow up I got one of my other mfx that I use on my other bow with the same setup, but shorter and it's showing weak still? That doesn't seem right does it? So I go get my 56# longbow and shoot the arrow and it shoots great. When I don't get all the way to anchor it shows stiff, so what is the deal with my Jk bow? Could you tunning gurus please help me.I hope this makes sense
