Folks keep sayin' they want new chamberings for the Handi rifle so the folks at Profino Firearms, a wholly owned subsidary of Manny & Red, Inc.
, have responded. Introducing the .308 Chipshot, available in both rimmed and rimless, in an effort to satisfy Handiholics no matter what side of the street they choose to walk down.
308 Chipshot Ballastics,
190 grain Jacket HPBT @ 930 FPS - makes round holes at 100 yards, no keyholes after couple a dozen rounds.
Parent case - Rimless - 35 Remington
Parent case - Rimmed - 445SM or 44 Mag (short neck version)
Brass trim length 1.42", case capacity about 30% less than a 7.62x39 on the rimless version, holds a bit more powder on the rimmed model.
Headspaced on the shoulder for both versions. Going with the rimmed cartridge as it eliminates neck turning, the 35 Rem neck is way thick after forming.
Chambering was performed by removing about 1 1/8" off the breech end of a Rem 700 30-06 takeoff barrel. Rem barrel turned and fit into a 18 3/8" Pardner shorty cylinder bore, required a muzzle end sleeve. Barrel is interference fit into the shotgun barrel and is kept for moving forward by the rim and shoulder of the liner barrel has was made to fit tight into the 12 ga chamber.
All work on the gun performed with hand tools and a dremel, bench grinder and 1" table mounted belt sander. No lathe or endmill used. Gun has a working ejector system. I did deviate from Profino standards by using the GBO crown cutter on the muzzle and a counterbore for the rim cut, but I turned them by hand.
Purpose of this little exercise was to prove to myself I could build a liner barrel handi without using "real" metal working equipment. I may try and do a Profino "stub" barrel at some point just to see if I can. Will post pics of gun and liner barrel later. As of this morning, Gun has a scope so will try and see what kinda shooter it is.
