I bought a new 14.5" middy upper not too long ago from a very well respected company. The first time I shot it, it shot horrible. I had no feeding or ejection problems but I was literally getting 3 foot groups while trying to sight it in at 50 yards.
I notified the company and they had me send it back so they could check it out. I got a email from them today stating that they were changing the barrel. They did not say what was wrong with the barrel or what they found that caused them to make that decision.
My question is is what can be so bad about a new barrel that would cause it shoot that way and the company decide to change it? Bad crown?
I was wondering if one of the more educated members here could give me some ideas why they would decide to re barrel it. Thanks!
May not be the barrel, may be the chamber. I have a Remington M700, heavy barrel 243, shoots six to eight inches at 100 “all day long, if I do my part:D”. Examining the fired cartridges, they are “inflated” near the rim because the chamber is too large. Probably the reamer was off center when it was run in though it could be other things. You can put a cartridge in the chamber, put your pinkie on it and wobble it around a lot. If you have any fired cases on hand examine them, look for a slight bulge near the head. Doesn’t take much to mess things up.
In terms of what “said” company found on your barrel that deemed it worthy of replacing…my guess is the barrel had excessive tool marks or a bad burr and even though you prob. tried to visually inspect it with your naked eye and nothing stuck out, under a bore scope it would have and the company def. would have bore scoped immediately.
I think the point is pretty clear. The Op isn’t trying to point any fingers. He merely asked a question, in an attempt to gain further knowledge. Isn’t that why we’re ALL here?
Since the issue already taken care of you can list the manf. It doesnt do us any good to post threads saying you had a problem with X brand part but wont say what the brand is.
Im 95% sure I already know but it doesnt hurt. I think this brand got some real bad barrels from their supplier, and we’ve seen a few with the same issue in the last 2 months.
You followed the rules, you gave the company a chance to make things right and they did. I think you are clear to share who it was that had the good CS.
Actually the if you read the Mission Statement under Rule 4 it states to contact the dealer or manufacturer first. I think we do the best to enforce that rule.
Having said that it can sometimes be difficult to enforce when the said company is a “repeat offender”.
am i the only one who doesn’t give a rip who the manfer was?
as to the question… the topic of the thread, and all…
bad muzzle could do that- if it was REALLY bad. i guess if it was that bad, re-crowning might not be an option.
was it keyholing? might be a leade issue. when the firing pin strikes the cap, the cap pops and shoots the bullet into the leade. how the bullet lodges into the leade, awaiting powder combustion, determines how the bullet will travel down the bore and pop out the muzzle. if it lodges into the leade all cattywompus, it’ll fly all cattywompus. leade problems usually cause keyholing, though.
for groups THAT bad, it really sounds like a loose barrel… perhaps it had an under-sized barrel extension on it, or an otherwise bad/misfit barrel extension… something to cause play. every time you fired, it’d move the barrel.
just speculating/throwing some stuff up, obviously.
I guess the question is, what did they do and when to rectify the situation and identify the out of spec barrels before sending more out? Do they laser boresight their uppers or anything along those lines? You’d think they’d have caught something like that during test firing if it’s more than just a function test.
The company is BCM. The only reason I didn’t say who it was because I posted this thread before and it got pulled because they didn’t have the upper in their hands yet. I was still waiting on my call tag to come.
Over the years I have owned or shot rifles that have been shot with corrosive ammo and left to rust leaving some pretty ugly bores. The accuracy of some of these guns was surprisingly good considering. On the other hand, I have seen M1 rifles with muzzles worn out from cleaning which, despite an otherwise pretty good bore wouldn’t hit the barn. The two critical parts of a barrel are the chamber and the muzzle. An oversize or eccentric chamber if fatal to accuracy.
And Paul is taking care of you with no problems. Knowing him and how he works, I expect nothing less. Every company has a problem once in a while, the good ones fix them quickly and hassle free.
