Sweet. I have the reamer for the x39 an at 1" they would work on some bolt actions (not remington 700) like the mosin or ruger or win. I see a 1" bull barrel target build coming soon that will also shoot factory loads. Now I need some one to make cheap over sised gas blocks or a sagia shot gun clone. If there decent I may get a few and chamber them and sell them possably. a 1" bull barrel mosin would be cool.
The barrels are 1"x20" unchambered non profiled .310" rifled blanks. I have no idea why they advertise them as 7.62x39 when that is a chambering. They could advertise them as 7.62x25 or 7.62x54 or even 32 ACP for that matter.
