I have a major problem with my arrow and broadheads.
Im using muzzy 100s withGold tiparrows, 3555 with a 50 pound bow.
weight tol. +/- 2 grains
straightness +/- 0.006
I honestly have no clue what the weight and straightness mean and what that will change in the flight.

Okay the problem is that my arrows are are flying way off the the left and down some. when they release the arrow they are shooting perfectly straight, but once they get about 5-10 yards out they are starting to turn. the arrow is suppose to twist isn't it? Well mine do but at like 1 mph and sense it goes so slow it makes the arrow float to the right then go up then float to the left, as in a circle.
I've tried twisting the nock a little bit and it never worked either.

Just so you know the field tips arrows are shooting dead on.I have split one arrow and have broke a ton of nocks. My groups are usually in 3" circles.but with my muzzys, I aim dead on at the lungs and the arrow misses the deer. It curves and goes straight to the front of the deer.

Please help me. My dad is going to scheels in a little bit to get some hunting stuff. He is getting me some new broadheads. Probablymuzzy 100s. Please tell me If I need to get new arrows or a differant broadhead.
