Okay, /k/, I bought an abused and used Type 53, with a barrel so pitted you can't see rifling at the crown. This is the accuracy I'm getting at about 15-20 feet. How can I milk some accuracy out of her?
>>
>>32395998
new barrel
>>
>>32396053
Perhaps something less tedious, or expensive, or damaging to the originality?
>>
>>32396207
Shoot at 10 ft?
>>
>>32396207
Maybe have a gunsmith shorten the barrel by 1/4" and recrown it?
>>
>>32396608
Also, try some type of bedding compound for the barrel/receiver. Line the stock with Saran wrap first, so the compound isn't a permanent feature. If that doesn't work, rip it all out and try free-floating the barrel. If that fails, have the barrel bored out and a liner installed that brings it back to original spec.
>>
>>32395998
The rifle is finished
Get rid of it
>>
>>32395998
very carefully cut the first 1/4 inch off the barrel. then recrown

You might try lapping the crown; at this point you have nothing to lose.

Don't circumcise your carbine; just counter-bore and re-crown it like the Soviets did.

if OP had to ask for advice for this, i doubt he has the tooling to properly counter-bore.

all you really need is a hacksaw, files, and a power drill with a brass screw

I'd prefer not to cut of my rifle if I could. I'll look into lapping, free floating, then try a liner like >>32396705 assuming I can find a gunsmith.
>>
>>32396975
dont bother. if the pitting at the crown is as bad as you say it is, nothing will help
>>
>>32396990
What if I just got a new barrel, would /k/ hate me?
>>
>>32396990
Mosin barrels should be easy to find.
Find a decent one and rebarrel it.

As far as collectibility, don't worry. The only thing that makes chink carbine collectible is stock art. Other than that they're just shooters.

>>32397071
What all would I need to do to replace it?

Are those 150 grainers?

Counterbore it like the ruskies did to restore a lot of their crowns post-war.
Same thing, without wrecking much originality or shortening anything.

Yes

Also, what is this gunk here under the stock?
>>
>>32395998
Have you tried going the rifling in place?

Take a better picture with more light.

Looks disturbingly like someone may have filled in some pitting with weld. But you've already shot it, so if it didn't blow up then it's fine.
>>
>>32398357
Would it mess with accuracy? Should I remove it? How?
>>
>>32398399
Only pitting inside the barrel should matter.
>>
>>32398399
Especially at the crown.
>>
>>32398429
I mean the weld stuff. Won't it mess with free floating?
>>
>>32398357
did you mean JB Weld, because that's what it looks like to me.
>>
>>32398118
Like others have said...That looks like putty/weld. Horrible...Wow. honestly I would just dump it.

I was asking if those were 150's because you should see if shooting heavy shit will tighten up your group. A lot of times these old guns won't shoot well unless you use heavy bullets. Its like Mausers. You just use nothing less than a 196grain bullet.
>>
>>32398634
I don't want to dump it. What can I do?
>>
>>32398728
How much did you pay for it? Sorry if you already said and I can't read.
>>
>>32398765
$230. It was a Christmas gift from my parents.
>>
>>32395998
Turn it into an Obrez

I mean, what do you have to lose at this point? It might even get more accurate somehow.
>>
>>32398503
I don't know, put your stock over it and see if you think it's pressing on anything.
>>
>>32398784
Eat it. It wouldn't be the first time I ate shit and lost money on a gun I ended up not thinking was good enough to be in my family. I'm very picky mechanically. I could care less about cosmetics. Your gun kind of falls into mechanical because of the pure... Bullshit some subjected her to.

Maybe sit on it until you can find something else. You say it was a gift from your folks...I'm going to assume your young. I'm 35. Guns are tools man. If you keep her, thats a good don't give a shit about it gun. Don't baby it. She's a filthy whore.

The M44 was designed to fire Soviet L-ball, which is 148gr.

>>32398875
Alright. She's ugly, and I'll make her work for me.
>>
>>32397622
YouTube
A barrel vise
A receiver wrench
Penetrant
A butane torch
And a big cheater bar
>>
Fuck it. I'm going to keep her as is and just use heavier rounds.
>>
>>32398987
Then it might effect the point of impact by some small & unknown quantity. But IDK about it widening groups like your OP pic.
>>32400404
Only things heavier ball ever did for me was cost more, drop faster, and bust thick ice a little better vs 150gr. I'll only use the stuff for ice busting now, feels worse than light ball to me in all other ways. Pic related, light ball vs heavy on the right.
>>
>>32398987
Either grind that stuff off, or see if you can grind off the area on the stock that's pressing on it so hard until you're back to a more/less free float. A dremil would probably make short work of it.
That's terrible.
