Carbine Bores

[garrettbragg12]

I posted this topic awhile back, but never posted any pics. I'm curious to whether or not my carbine has a good bore and muzzle. Best pics I could do with a phone. Attachment 38626

Thanks for your input and picture Dave! Glad to hear my battles not too shabby!

garrett, I'd say your muzzle is at least a '1' to '1.5'. You can see that it takes a little more of the M2 ball than Dave's, which definitely looks like a '0'. Your bore looks good, with very distinct rifling. Carbine rifling, like the .45 pistol, is light to start with and the relatively low velocity and pressure was very kind to the bore and chamber. Plus there was no corrosive carbine ammo, so most bores remain serviceable unless totally abused.
Incidentally, I have taken to using only nylon brushes in all my guns and highly recommend it for the collectibles.

Dave, yours is about the same as my 95+% Inland. Bad pic, as it is from a slightly upward angle, so it looks less than it is showing. It is a full 1/4".


My Standard Products mix-master shows 3/16".


Both are excellent shooters, so OPs should shoot well, especially if the action is hung in the stock properly.

I appreciate your pictures and input! What do you mean by "if the action is hung in the stock right.."? Is there an incorrect way to put your action?

Rifle Sales - Carbine

Check the links from the CMP carbine page above. A barrel receiver should be "hung" in the recoil lug where there is 1/8" between the barrel and the channel in the stock. If the gap is too big (1/4"), it deflects the barrel down. If there is no gap, the barrel floats around, and decreases accuracy.

My repro folding stock is snug as a bug, so I'll have to try my original stock! Thanks for the link!

Randomly selected carbines were shot 6,000 times and any problems were noted. To show you how easy on the barrel these weapons are, some of these test carbines, after 6,000 shots were simply cleaned up and sent out for issue. A Garand would have a seriously shot out barrel by that time. Another consideration is that many of these guns were carried by cooks, mechanics, artillerymen, staff officers etc. and were not fired a lot. The ones used by infantry were used up and rebuilt.

My NPM has its original IBM barrel and the only flaw in that barrel is a bit of pitting directly over the gas port, probably from water entering from that hole. It shoots lights out at 100 yds.
