Hello, I have a four year old Browning A Bolt, 270WSM.
A few days ago while chambering a round it went off.
When I first pulled the rifle out of the case it had an expended cartridge in the chamber. I ejected that casing and then tried to load the live round. It went off....scared the hell out of me and did no good to my Ford..
I am not familiar with an a bolt, has the trigger been adjusted?, did you get the bolt lever closed before it fired? If the trigger has been adjusted and it fired as you were locking the bolt then the trigger is too light. Otherwise you probably have a bad bolt. I would take it to a gunsmith.
I've got several a-bolts, as well as working on more than a few and I'm POSITIVE somebody has screwed with the trigger. PLEASE take it in to your local QUALIFIED gunsmith. Somebody has had ahold of this good rifle and in the process of "bubbatizing" it, made it into an unsafe nightmare. ANY rifle can be messed up by somebody who don't know what he's doing.
It's posts like this that make people wonder about or shy away from perfectly good products. I don't even know why he posted it as I AM very familiar with A-bolts and I KNOW FOR A FACT some kitchen table bubba has screwed up the trigger on that particular A-bolt. Being familiar with the design, it's impossible for an untouched (factory), or responsibly adjusted trigger to just "go off" like that. I noticed he never came back and tried to deny it-not that it would do any good anyway.
