<HR class=hrcolor width="100%" SIZE=1> harrington and richardson single shot .223 $277 http://www.hr1871.com/Firearms/Rifles/hunter.asp
Not in those particular calibers or models.... I have shot a lot of single shots from .22 short to 10 gauge. The best (or the worst I should say) was an old Sharps .45-70. Hit the target, and I was done for the day. ( I never shot one of those again) I figure a single shot is as accurate as any bolt action rifle, and wastes no energy in operating a bolt/gas piston system. In the 2 calibers you mentioned, I'd think they would be quite good, except, if you needed a quick follow-up shot! I like the .308 version, but then I'm no hunter and a lot prefer the smaller faster loads/calibers (flatter trajectories and all that). Bill
Folks that own the H&R rifles like them. My only centerfire singleshot is a BRNO ZBK110 in .22 Hornet - broadly similar style and appearance to the H&R, but better looking. It's made in a variety of calibers too. Once you get the H&R, you can have more barrels fitted to it - have to send them the action though. It's not just a matter of ordering and popping one on. One thing to remember though - NEVER shoot surplus 5.56X45 in a .223Rem sporter rifle. Bad juju.......
I have one in 223 with a 3x9 scope. Great rifle, have shot everything from varmints to deer and a 500 pound buffalo with it (behind the ear head shot). Light weight and accurate, you will not be disappointed if you get it.
