hrmm i own a marlin 917v its out the box a tackdriver out past 175 easyly. useing a bipod and fairly crapy optics. and hits better than a .22 mag i have seen this round change non shooters in to avid ones and is impressive.
i also have a .17 HMR autoloader and is the only auto thats not recalled in this cal ... but it is a AR-15 too lol Alexander Arms still sells there upper in .17hmr at about $650 a pop so it is a spendy unit to get together add in 250 ish on a lower and it was a little quarky at the first 150 rounds or so .. had a few stovepipes at times ... mfg said this would happen but by the 200th round it runs like a fine clock.
the early autos had loads of issues with getting things balanced to hold the bolt shut long enuff to let the pressure subside to safe lvls. and still properly cycle the wep. also a lot of mfg tryed to use the .22 wmr they had at the time as the donod to there 17hmr attempt . most lacked a function to not let them fire "out of battery" this led to case ruptures and exploded guns . all of these issues AA solved . also a side note most the ammo i see today says "Warning Do Not use in semi auto firearms with out consulting your firearms mfg"
