The Shadow Knows...
I'm dancing around three Izmash carbines. A 1943 m38 and a 1944 m44 which are both counter-bored at the muzzle, and a 1945 m44 that has NO counter-bore.

Can anyone explain the change, is the counter-bore a good thing?

Thanks for any info!
 
It's my understanding that the CB was done as part of a rearsenal process where a new crown was made inside the bore because the old one was just too eroded.

It doesn't mean the rifle is a bad shooter.
 
Counterbores get a bad rap for being unpleasing to the eye, but they typically shoot very well. For me personally, pull the bolt on all 3 and check the bores.
 
Counter boreing is a a common way to restore accuracy, so have no fear, its part of the 'process' in being brought to spec., after the wars end and the Soviet Union was refurbishing its arms for the next war.

It very much part of the rifles history of the carbine, as is the cosmo that was slatherd on to protect the metal and the shellac that protected the wood , in storage, awaiting WWIII

The 1945 made carbine most likely missed extensive war use and didnt need the crown restored.
 
I will be finding out about the 1944 M44s accuracy VERY shortly.. :)


Back from mowing and shootin- does well enough for me. Popped 10 rounds at a rock outcropping 150-175 yards away in heavy wind. Each round hit the rock I was shooting at (could be a 10 inch group for all i know)

Counterboring is not an issue if it's done properly.

The Russians did it like their lives depended on it ... because the did!

There is no reason to believe that a non-counterbored rifle will shoot better than a counterbored one. They were all arsenal rebuilt to the same functional specs.
 
I knew they changed the name, didn't realize the city remained the same. They changed the name of Stalingrad a few times, and Saint Petersburg if I'm not mistaken.

I've never heard of it being called Izmash until the AK's started rolling out. Everywhere else I've always heard of it being called Izhevsk.

It is a bit like saying that Bowling Green,Ky makes Corvettes.

Izhevsk is a city so it doesn't make anything, but the entity that does the manufacturing is located in that city and incorporates the name of the city into its own.

Same goes for Tula.
