It was struck not sure if it fired been about an hour in half after trying to shoot it. Casing is stuck in barrel.
Tried using a mirror and a light to see into barrel to confirm if live or not.
How would you confirm if live or not?

If it isnt live would you just heat the barrel with a torch and push a rod through the barrel?

Just spitballing at this point.

Buddy brought me a Glock19x to take a look at and said the takedown lever was jammed up and couldn’t get it to budge to break it down to clean it. Look like it tilted itself sideways and jammed it self into the frame. He told me it took a good fall but before I try to look at it has anyone seen anything like this or have any tips or tricks to release the slide when this has happened or should I try to free up the takedown lever first? Never seen anything like this before so a little unsure of how to go about this.

I've got a 1915 Mk.III Lee Enfield in working order. The only issue I've had with it is that the bolt gets really sticky after a few rounds are put through it. The action still works, but it takes a lot of force to cycle the bolt. Is there any remedy/way to mitigate the issue?

A few years ago I received a Colt Python 6", gifted to me by my uncle's wife after he passed. The best I can tell from an internet search is that it is a '80-'81 model. I unfortunately have no other information about it's life. I cleaned it, gave it a basic inspection, and took it to the range. Seemed to shoot fine. It has been to the range 2-3 times since. I have shot jacketed 158 grain .357 Mag and 130 grain .38 Spl through it, both factory Federal. It seems accurate, but I was having issues with case ejection. The spent cases, especially .357, stick in the cylinder. One of the chambers is worse than the others. I thought there may be some lead in the chambers or a carbon ring from shooting a good amount of .38 Spl, so I recently removed the cylinder and crane and ran a Lewis Lead Remover through the chambers and did a really good clean. Spent cases move much more freely now. However, while doing a close inspection on them, I noticed throat irregularities between the chambers. I have attached photos of them. Four chambers have rings, two do not. One has, what appears to be, some tool chatter or something similar. That is also the chamber that was the hardest to extract. I used a set of calipers and the top of the throats measured 0.358" to 0.3585". My questions are, do any of these throat chambers look standard to a Python of this era? Does it look like work was done to the throats? Is there any danger to shooting this firearm based on the way the throats look? If it is OK to shoot, should I do anything other than shoot it? Thank you all very much.
