Bore question

[win]

My question is where do dark bore come from?
Is it from guns that where not cleaned in a timely manner?
I guessing the troops cleaned them when they could but their might have been days between cleanings.
Did the Russians rebarrel rifles? I would guess they did if it needed it. I have a counter bored rifle. I going to guess that it is the original barrel. I have also read that counter bore is not a bad thing. thank you to this sight. I feel much better about my rifle.
Anyway just looking to increase my knowledge of these great rifles.

Yes dark bores are from the corrosive ammo they used and not getting cleaned up as fast as needed in most cases. It's basically small pits in the metal. It's common with mil-surp firearms. Yes the Russians re-barreled rifles. You'll find different year receivers and barrels on them. They did whatever it took to make a rifle serviceable. That included reusing any part that was still usable. Counter-boring was done to correct a worn/damaged crown and to remove bad rifling at the end of the bore. Most times it was from cleaning them in the field with the stock cleaning rod which is the same metal the barrels are made from. Counter-bored rifles in my opinion are not a bad thing.

How much does a dark bore affect accuracy? The clearer and sharper the rifling the better.
thanks again

There is no rime or reason to how a bore looks to how it will shoot, in most cases. I have some nice bores that can't get on the paper and some semi-sewer pipes that are tack drivers. You just have to shoot it to find out.

"AMEN" to that. I have a SAKO M39 #2 Barrel that looks like crap that will out shoot my "better" barreled M39's. Just is.

LOL, I have a 1926 Izhevsk with an absolute sewer pipe for a bore that shoots lights out. I ordered the gun from AIM several years ago, and when I got it I was appalled by the bore...........and then I shot it..........first at 50yd, and it shot great. Then out to 100yd. Again, shot great. Finally, I pushed it out to 200 on an 8" steel plate.......and hit 5 for 5. I went home happy and confused all at the same time.

Lots of reasons, sometimes in the press of battle it is not possible to clean a rifle daily, or even for days or weeks at a time, sometimes a fired rifle will lay in the field next to it's dead soldier for a long time before it is collected up, and the bore rusts. Soldiers are sometimes poorly supervised and bores rust, rifles can also be poorly stored once out of service, or even during it causing rust. Bubba civilian owner is sometimes a clusterf*** and doesn't bother to properly clean his weapon, or clean it at all resulting in rust for the next owner to deal with.
