Bought this rifle at Wal-Mart, $163. Single shot .17 HMR with factory bull barrel. This was the absolutely most accurate out of the box rifle I've ever owned. I zeroed it in for bullseye @ 100 yards but I may go back and re-zero for 1.5 inches high @ 100 yards. According to Chuck Hawks: Hornady trajectory figures show that when zeroed at 100 yards, this bullet hits only 0.1" high at 50 yards, and 2.6" low at 150 yards. A better way to zero a .17 HMR rifle is to put the 17 grain bullet 1.5" high at 100 yards, for a zero range of 145 yards. It would then hit about 0.9" high at 50 yards, 0.3" low at 150 yards, and 5.5" low at 200 yards. The maximum point blank range (+/- 1.5") of the cartridge would be about 165 yards, at which range the bullet retains about 90 ft. lbs.of energy, enough to remain effective on the smaller varmints. .17 HMR On the plus side, with a MPBR of 165, it doubles the range of my .22lr. On the down side, at 25 cents per round, it is almost nine times more expensive to shoot than the .22LR at three cents per round. As for the firearm itself...it is sturdy and well fitted...the only problem I have is the bull barrel makes it nose heavy in the extreme. The synthetic stock is hollow, so I'm thinking I'll swap it out for a walnut stock with an adjustable comb.
