factory crooked barrel survey

[jbunny]

how many people have rifles that have the barrels screwed in the actions crooked??/
I have had 2 , one just lately. mine were both rugers and 77/44. one was an older from the 1,st
batch of bolt action 44 mag and they replaced with a rifle on my choice. this last one is another
77/44 and I have a new one coming from the factory. the first one was barn door accurate and that's how I found
the barrel was crooked. this was the first one. a straight cleaning rod would work . one should lay the rifle flat
on a table to check for up-down crooked.

You ever look through a collimator on those rifles? I bet that could be interesting. I see crooked chambers on almost every factory rifle I check out. But as long as the end of the barrel is pointed in the right direction they still work. But you get the muzzle off that far, either from a crooked face on the receiver or a bent barrel and it gets really hard to get a scope to line up.

It happens at times, in the thread/chamber/fit operation, if the machinist isn't paying attention.
When I was with Montana Rifle Co., I was called up to the custom section, as they had a rifle that wouldn't shoot. I told them it wasn't fit correctly, and the barrel was crooked. The guys working on it couldn't see it, so ignored me, and kept messing with it for a couple more days, before refitting it. Shazam! All of a sudden, it shot correctly. Then the boss was mad at me for knowing the answer, and at the other gunsmiths for NOT knowing and wasting the shop time.

That is one I've never been able to figure out. Why knowing what is wrong, stating it and when it's proven to everyone your correct everyone gets mad at you.

Yup, thats called insecurity gone to seed!!! Their barrels are on crooked also!

Barrels not fit square and true are one issue bores not straight and true as the drill wandered, Fixtures worn or chips swarf creating issues are all problems. I have seen barrel shanks not cut square due to muzzle not supported and running out of round. I have seen blanks not drilled straight and where drills wandered due to uneven chip loads build up. Seen one barrel a 3" pin gage would freely enter both ends to depth yet one .001 smaller wouldnt drop thru as bore was "bowed". Looking thru it it appeared oval due to this flaw. These issues are why barrels are indicated in on both ends whenever possible. When shank threads shoulder and reciever are square running the barrel in by hand will give a thunk and ussually need a wrench to loosen. Any thing not square and you get a tink and barrel will loosen easily. On actions with a recoil lug sandwiched between barrel and reciever it can throw things of also if not parallell too.

If it isn't bad enough to fit a barrel like that, what's with letting it leave the factory like it? Have they no quality control checks in place at all?

You probably would do well not to look at a rifle too close or you are bound to find something wrong.
Crooked receiver threads are usually going to be a factory tooling problem and there will be lots of them in the same condition.

So far as I know I have never had receiver threads as crooked as the photos above.

I have had 2 factory barrels that bore sighted 18" from where they pointed.
I once saw a new Remington 788 in .30-30 that was bowed at least 1/4". You could see it from the side 10 feet away.

I once had the ticklish job of boring a Remington Hepburn chamber neck out .004 to permit the use of grease groove bullets.
The rifle was a .40 - 2.6 SS. When I dialed in the chamber I spun the barrel and looked through it out of curiosity. The bore looked like it was off center half way through and it flopped around like a jump rope when turning.

This milsurp was 'way off, but a set of those special 2-sided Weaver rings corrected the problem. The bore is pristine and it shoots like a dream.
