noknees, I toted a 20" synthetic stocked matte finished M70, factory mfg. in 7mm-08 all over Colorado after Elk and Mule Deer about 15 years ago. They were mfg. in 257 Roberts and 250 Savage ALSO, albeit short runs, the latter also had 1 in 14" twist IIRC.
NOPE, Winchester has ALLOWED Rem to sell their Whimpy Whippy barreled M7s to no end, in a Rem named round on their baby, the 7-08.
Winchester IIRC is owned by the same Co. as Browning, the latter did a good number of Abolt's in Micro Medallion and Micro Hunters IIRC in 7-08 and others.
YES, ironic Winchester was known for the handy '94 30-30 and yet NOT mass produced a carbine in say 20" w/short action.
