Hey
I have one 15 1/2" , Fishgill brake , I love it , took a bunch of deer with it last year , can't wait to hunt it again this year . My load is 78.0 grs of 414 under a 300 gr Sierra boat tail with mag primers about 2350 fps out of mine. 3" high at 100 yds dead on at 200 and 12" low at 300 . a little heavy for deer , aim for bones ,KEEP THE FOREND SCREWS TIGHT , Good Luck !!
