i'll start off with the one thats actually shooting. the others still need chambers cut and other work before they make a trip to the range.
this one is chambered in 220 swift AI. its built on a hex receiver & the barrel is from a remington 722 that was originally chambered in .222. i rethreaded & re-cut cut the chamber to 220swift AI. i soldered a bushing to the bolt head to reduce it down for a .473 case head. i also had to shim the extractor back .010 & slightly deepen the extractor slot in the bolt head. i had to rework the interrupter/ejector so it would protrude farther out into the action to hold the cases in the magazine & catch the casehead to eject the spent cartridge.
modified bolt head
barrel being threaded
220swift in magazine before fireforming.
after fireforming there is about .015 space from the shoulders to the inside of the magazine.
the sights were way to low to use comfortably.
first 3 shots went into right at a 1" group. i wasn't really trying for accuracy, i just wanted to see if it had potential.
i couldn't hardly see the front sight so i swapped it out with a brass beaded front sight that was in my range bag and shot 3 more times.
these are from a standing rest at 50 yards. it came out to right at 5/8"
eventually i plan on putting it in a european classic stock from great american and installing a sidemount with a weaver k-6.
this one has a finned 7mm barrel from a madsen light machine gun. i'm going to chamber it in 7mmx54r. to cut the chamber i'll just put a 7mm pilot on my 6.5 vostock reamer then use a 7mm neck & throat reamer to finish it. i'm still working the stock, once i get it to my liking i'll glass it over & paint it. the bi-pod is borrowed from my ar-15, it will get a parker hale style bi-pod mounted to a stud sticking out the front of the stock. i still have to figure out what i'm going to do with the bolt handle & optics since i don't really care for any of the off the shelf mosin scope mounts.
this barrel is from a russian maxim machine gun, it will remain in 7.62x54r. i'm considering building a winchester marksman style stock for it.
this one has one of the czech uk-59 machinegun barrels on it. it will also remain in 7.62x54r. the receiver is from a romanian m44. the gap in the rear bridge has been filled and the bolt handle has been moved to the rear of the action.
timney trigger
the timney triggers are nice. i got two of them before they sold out their first batch.
i'm also planning a target rifle chambered in 6.5 vostock & a dg rifle in 9.5x54r
