220 Swift Ai Mosin Project

Recommended Posts

this one started out as a slightly sportered remington m91 that thought it was a shotgun intead of a rifle. after giving up on making it shoot it sat in the corner for about a year untill i have the wild idea of putting a remington 722 barrel on it that was stitting in another corner of the room. the remington barrel was originally chambered in .222.

i threaded & chambered the barrel on a grizzly mini lathe that i picked up for next to nothing. i think they call them a mini lathe because you can only take a mini cut with them. it was the first thing i've threaded in about 10 years & luckily it came out right.

i'm going to take it to the range tommorrow and see if it shoots.

the sights that are on it now are from my junk boxes and will be replaced with something a little nicer in the future.

i still have to do something with the bolt handle & do some magazine & feeding mods.

my bannerman will feed a 220 swift round so i'm going to copy the ejector & interuptor on it. i'll also have to make a spacer for the inside of the magazine.

eventually i'm going to put a sidemout with a weaver K6 on it.

Lookin' good man!

 

The only thing I'd think about is moving the bolt handle to the rear of the bolt and making up a scope mount that straddles the rear of the receiver so you could mount the scope in the "traditional" way.

I've been following your other posts in "sporterizing'.

 

Do you have any other references for you conversions aside from you Bannerman?

 

If there is something that you could post a link to, I for one would like to see those

references.

 

Thanks Much!

I've got an M44 that I'd like to do something with.

the only reference i have is my bannerman. they use the early one piece interrupter/ejector & they are slightly extended to work with a rimless case. i'll take some pictures of a bannrman ejector/interruptor next to a factory one this weekend.

i'm also only going to use hex receivers on my builds since the later round receivers don't have the inner ring and two sections of the threads were broached out when the cut the bolt raceways.

 

i made a trip the range this morning to test it out and its a shooter. right now the sights are way to low to use comforably. both targets were shot a 50 yards from a standing rest.

on the first target i put 3 rounds into a 1" group, i wasn't trying for accuracy i was just seeing if it had potential & i couln't see the front sight bead very good.

i swaped the front sight out with a brass beaded one from my range bag and fired 3 more times.

it came out right at 5/8".

its a keeper so now i need to order a real stock, a timney trigger and some sights

here are a few pictures of the bannerman ejector/interrupter assembly. it isn't actually lengthened its just modified so it will stick out farther. bannerman is on the bottom.

ejector/interupters bottom is a banerman. the other one was cracked at the screw hole & broke when i removed it. i may tack it back together, it still works but it comes loose rather quickly.

i modified the broken one by removing the interupter and the tail. it works.

220 swift fits the magazine very close. i stil ned to add two shims that are about .030 to the rear sides of the inside of the magazine to take out the side to side slop.

220 swift ackley case shoulders just fit inside the magazine. thee is maybe .015" space betwen the shoulder and the inside of the magazine.

220 swift in the rifle. they are feeding and ejecting. i still ned to do a litle work on the feeding. sometimes the tip of the bullet will catch the edge of the chamber instead off feeding straight in. the bannerman has a slight radius where its hitting on this rifle. i'll see if i can get a dremel in there to put the radius like the bannerman has, if not i'll pull the barrel and do it.

220 swift AI cases will feed. i need to fireform a few more cases then load some up to tweak the feeding.

I like what you've done with this one and the bolt head you bushed Got me to start thinking. I went out and put 243 dummy rounds in mine and it feeds them good also 7x57 and 6mm rem. 8x57 binds just a little at the front of the mag on the wider shoulder of the 8x57 case. I need to get my bolt bushed and adjust the extractor like you did. Do you have any pics of how you shimmed the extractor. I have not worked on any mosins so this is a learn deal for me. The bolt is a lot like a carnaco but differnt at the same time figuring it out as i go. Have you mounted a scope yet. If so what base did you use? My mosin has the hex receiver it is the only one I have and the bore is trashed so I have been thinking of doing something along the lines of what you have been doing with yours.

james, to shim the extractor i removed the extractor then cut a small piece off a feeler gauge & put it between the extractor and the bolthead when i re-assembled it. i didn't take any pictures but once the extractors off you sould be able to figure how big to cut the shim & where to put it. the shim is very small & easily dropped during installation so i would make several of them. i used a pair of scissors to cut the shims. i also replaced the .010 shim with a .008 shim since the .010 shim made the extractor a little to tight on the rim.

i plan on doing one in 7mm mauser and one in 6.5x55.

 

i haven't put scope mounts on it yet. i tried out two sets of vintage side mounts i had but both of them put the scope to low so i'll have to figure something else out.
