Aulrich, will do, once I get to shooting it. Right now the barrel is at the 'smiths, being fitted to the frame ( no luck in having it fit "out of the box" ). I'm also having the 'smith rechamber the .22 Hornet "donner" to a "K", and fit a .280 barrel to the same frame. I do have the forming dies and reloading dies for the .17A.H. waiting, so things should come together before long.
I've used the .17 HMR for ground squirrels and marmots up in B.C. since the Marlin first became available. I think the extra velocity of the A.H with 20 gr. bullets, or moving up to 25 gr. bullets will be much better for the big Marmots, or the occasional 'yote, without going to the larger ( noisier ) .17 M IV.
Maybe Hornaday and H&R will "domesticate" it some day??
