Bolt stuck closed, live cartridge on chamber

[Jamnanc]

I swear I've seen this asked here, search foo is weak this evening. I have already removed both pins, separated receivers, then gently pried the bolt loose. Problem corrected. My question is how do I stop it from happening again?

Its a newer bushmaster xm15 factory gun. The cartridge I removed was dirty and greasy, but fits the chamber fine. It was a 55 grain soft point and the point was not mashed or sheared. Am I getting too much lube in the chamber when I clean? I have had only one other malfunction with this rifle, I blew out a primer and it got into the feed ramps.

On another note. Before this it made my first sub moa five shot group with barnes 53 grain xls.

Yes, no , maybe.
IF it happens again. POINT THE MUZZLE UP AND AWAY FROM YOU. Preferable in a safe area. Take one of your feet and use your heel against the charging handle to cycle. OR a sharp rap of the butt stock on something firm, with muzzle away from your head and safe direction.

Thanks Jim. Your a help. Too many variables? I was at an indoor range, they wouldn't take kindly to the hammer method, they don't give your fee back if you get kicked out for violating da rules.

Brass case?

[Jamnanc]

Yes, brass.

readjust the sizing die, based on our pm.

Lube?

Lube in the chamber or sizing lube left on the brass is not nice for your gun.

You shouldn't have oil in the barrel for that matter. It can create too much pressure. If you use excessive oil after cleaning, run a couple dry patches down the bore before you shoot it.

I have to ask about the range rules issue. How exactly is performing a safe and properly executed clearing drill (mortar - up and downrange) more unsafe than walking around with a hot round?

[Jamnanc]

One is really obvious. Casing the rifle and maintaining muzzle control can be done safely and discreetly. Shouldn't be any lube left on the ammo, could be some CLP running down the bore during storage, if the answer is as easy as cleaning the chamber and assuring a dry tube, I'll be happy.

Was there not the option of simply firing the round safely down range? That's typically how I deal with a live round in the chamber.
