Anyone thought of building a 7.62 type AK chambered in the Special Ops guys 6.8mmRemingtonSPC? The SOCOM guys seem to like it (the SPC "special purpose cartridge") better than the .223 in the Afghan. The 6.8mm has better ballistics than the 122 gr 7.62x39 & 55 gr .223. The 6.8mm bullet is .277" (actually the older .270 Win caliber). Looks like a barrel could be re-made from Mauser to AK dims. Factory 115 gr ammo & empty brass boxer cases are available from Rem, Hornady & Silver State, but is costly & requires trimming the bullet tips a bit to fit into 7.62 mags. The 6.8 cases are a bit longer than the 7.62x39 cases. Cartridge case head dia's are similar to the 7.62x39. Handloads using 85 gr Barnes or Sierra 110 gr bullets seated a little deeper into the 6.8mm cases would eliminate the need to trim bullet noses.
New 6 gr button rifles bbls in .270 Win are available from Brownell's for $83. Chamber reamers in 6.8mmRemSPC type II are available from Midway for $116. Plenty of .270 Win bullet types are available. 6.8mm reloading die sets are available from RCBS. We're talkin reloadable boxer non-corrosive stuff ...not a real need to worry about chrome lined bbls. Sort of a "wildcat", AK. Now for a real good lathe jockey .......
The Brownell's barrels are also available in 6.5x55 (.264") & the 6.8 cases could be easily necked down to take .264 bullets. Pacific Gauge & Tool can provide reamers --even pull-through types ...wow! a 6.5x6.8RemSPC wildcat AK ...........hmmmmm .......wonder how much it would all cost?
But then it really wouldn't be a AK if it wasn't a 7.62x39 or 5.45x39 or .223 ...or would it?
