A note from down under, I shoot the CZ 527 carbine. Recently got hold of some CFE BLK powder this is the way to go 30.0 gr gave an average of 2,540 fps from that 18 1/2"barrel with hHornady 123 gr SST & Barnes TSX. I have three good size sambar deer to the SST all one shot and they are a big solid animal. Love x39 and would really like one of the new CZ's with the 22"barrel but the little carbine is a winner
