Thank you for your help everyone. I did use 2 different types of broad heads, both 4 blade. one was a slick trick and the other was a muzzy.

Both grouped right about a foot at 30 yrds and grouped straight on at 20yrds. I will test the rest which is a whisker biscuit rest, not a complete circular one but a 3 patch one that is supposed to allow the fletch's pass through without touching.

Thanks again

Joe
