Hey guys. My Mossberg ATR bolt won’t slide back. Bolt lifts, needs a bit of a thump to open all the way, but it gets stuck there.
I had a round in the chamber so I fired that to make the rifle safe.
Any suggestions - or is it a gunsmith job?

Knock it down with a bit of wood. Give a few taps. It will come down. Then have a think about what you did wrong.
Squirt a few drops of oil down the muzzle leave upright for an hour then tap with a piece of wood or plastic headed hammer. Or tap a cleaning rod down the barrel. Good luck.
What Muzza said.
Yep; don’t beat the bolt handle and taking it to a gunsmith is sensible.
As it seems the bolt will lift, and if you want to have a go yourself, things I’d try are (1) remove the trigger and bolt stop, just in case something is binding there; and (2) put a squirt of WD-40, CRC, Kroil etc down the barrel and then drop a steel cleaning rod repeatedly from about 1 foot in height (cut an old brush down to just the stub of you are worried about protecting the thread on the rod).
I’ve got every stuck case I’ve had (which is not many!) out this way without issue. Ditto a broken pull through once.
If they use a bolt design similar to savage or the omark with a floating bolt head it could be possible the cross pin has bent or snappedwhich would be more difficult to rectify.
Can u explain more on this as my Savage has been doing this the last few rounds on factory ammoQuote:

I don't own a savage but friends do and they are excellent rifles. The floating bolt head design is supposed to ensure better locking by permitting the locking head to "wobble" slightly and therefore align itself properly in the recesses. There is an added bonus that headspace is easy to ajust with different size bolt heads same as in the Lee enfield.Quote:

In theory this cross pin can bend or snap rendering the gun unusable.
The omark version had some early failures resulting in destroyed guns (the so called small pin version) so named because the far side of the pin going into the bolt body was only about 3mm in diameter and could snap under the load of closing or opening the bolt.
The answer was to double the size of that part to 6mm.
The photos are of an omark bolt complete and with the bolt head removed showing the firing pin and cross pin.
Hopefugly that's helpful
@Padox, I feel that in the interests of personal safety you should cease using the rifle immediately and to help you out, I will come down to Tarras with the 2506AI and shoot the Fallow bucks for you to keep you from harmQuote:

Gee thats not something I would like to be facing, at least treatment for young people has made spectacular gains in the last three decades. Good wishes to youQuote:

Thanks all for the sage advice. Being an impatient bugger and prone to ingoring those much wiser than myself, I gave it a gentle tap with a rubber mallet. Out it came.
The spent cartridge had a shiny ring of abrasion around the base, so I’m thinking I should have FL sized them. I usually just give a little shoulder bump, but there’s a chance these came from someone else (memory is terrible these days). Checked another round and the same thing.
Bummer… anyone got a bullet puller I can borrow?!
Oh, and yup - it’s got the weird cross pin bolt design. Thanks for the explanation, I wondered why it was like that as it seemed pretty easy to wiggle loose
poke loaded round in press with no die...lift round up through threaded hole and carefully hold projectile with vice grips,you can pull projectile by backing the case back down...you might loose 1 in 30 projectiles to grooves from grips..or not. I have never damaged one beyond usable. have hammer type puller now.

Yes.
What Mick said and put some tyre-tube rubber inside the jaws - provides more grip and less damagingQuote:

Mine had the big cross pin when I got it but I proceeded (in my ignorance of youth) to crack the pin on one side by repeated dry firing. There's a shoulder on the firing pin that smacks into the bolt head pin if dry firing.
Probably getting spares now is a bit of a chore.
