This oddball converted Mosin uses oval rifling to escape Moscow gun control (VIDEO)

Russian arms maker Molot has released a bunch of info on their VPO-220 bolt action rifle that isn’t– the Lancaster-bore 9.6x53mm– designed to skin a gun control cat.
The Vintovka Mosina VPO-220 (ВПО-220) looks like a classic Mosin M91 rifle, a longarm familiar to Russia for more than 120 years and typically chambered in 7.62x54R. However, to comply with regulations in Russia since the time of the Bolsheviks, the gun is not “legally” a rifle, but uses a Lancaster Oval-Bore system instead to impart spin. The oval squeeze to the barrel is elliptical, turning to give the desired twist without traditional lands and grooves (stop us if you have heard this before– we are talking to you, Franklin Arms).
Named after Charles Lancaster, the British gunsmith who invented it in the 1800s, it has been around for a minute and the technology was fairly accurate, with even the occasional military sniper rifle chambered for barrels that used oval bores.
Not all had such good luck. As noted by the great Roy F. Dunlap back in the 1950s, “The Lancaster oval-bore was tried out by Charles Newton, but did not quite live up to expectations of accuracy.”
Why reboot a nearly 200-year-old gunsmith trick on
