I Second the XTP's, Great Blood Trail, Accurate and Devestating on Deer. I have'nt lost a Deer to a XTP ever! Powerbelts SUCK! Plus I also shoot them out of one of My ACCURA's that's sighted in with 100grs of Pyro Pellets, sighted in 2 1/2" high at 50 your Dead on at 150 and about 3 1/2" low at 180.
150gr's is WAY too much, go with the 100grs of Pellets and eventually try some Lose Powder. But for now the 100gr's of Pyro Pellets should be just fine.
