Thanks for the input guys

I have it installed with the standard launcher at present, but I think I am getting a little fletch contact as it drops.
Before I try the other launcher I will try changing my fletch alignment. I have been shooting cock vane out, so will probably try cock vane up and if I still get contact I will try the other launcher. What alignment are the people using it using?

Probably worth mentioning I am shooting FMJ's with 125 grain heads and 29 1/2 inch length, so it is a heavy set up and I doubt I would be getting anywhere near over 300fps out of it.
