305 troubleshooting (literal)

take out your gas piston and stick a 1/16" drill rod or drill bit shank in that hole on the bottom of your gas cylinder. It should pass thru into the barrel.

-After being fired, the action does not cycle and the spent casing has to be ejected manually. After 3 shots, the bolt locks closed and it takes a screw driver to pry it open and eject the spent round. The above picture I tried to slide the spent round back into the chamber, it gets to this point before it has to be “persuaded” back any further.

This is where we need to focus. Walk me through it.

Round 1 loads normally. You fire the shot. Now, the bolt is still in battery, no sign of having moved? You retract the charging handle, does it move easily? Does the case come with it, hanging on the extractor?

The second shot is exactly the same?

The third shot you need to pry it open. Is the difficulty with the movement of the bolt, or the case?

What happens with the 4th shot? Does it go back to being like the first? Or is it like the third, over and over indefinitely? What makes the cycle start over again, cleaning it? Letting it cool?
 
The first two shots are essentially normal. They are removed easily with the charging handle. The bolt does not appear to move at all through all three shots. The case comes out easily and is ejected normally until the third.
It does seem like if the gun is given a chance to “cool down” the cycle can be repeated. Also keep in mind that with three shots of commercial Winchester ammo I was able to manually eject the rounds with the charging handle. Anything fired after the third shot requires the case to be pried out with a screwdriver.
I’ve cleaned the rifle completely twice with no change in the issue.
 
It's been a while so someone that still has one can correct me but in the pic of the gas control valve shouldn't the pin be facing up and down not parallel to the barrel/gas cylinder? As it is now it's closed. Again going from memory.

This is part if not all of the answer. The OP has the gas valve closed which prevents the rifle from cycling. I'm not sure however why his casing is getting so firmly stuck.
 
If that spindle valve was in the OFF position, I can take the blame for that..... :evil:

It’s a common prank of mine from back in my Sharon Gun Club days especially for them rich Toronto Lawyer members with consecutive serial numbered M1A rigs at range 3 !!

Hope it works out in the end for you! :wave:

It does look like your gas valve is ‘off’, which explains why it’s not cycling in semi-auto. However, you shouldn’t have extra hard reaction even with it turned off. Are there any marks on the casings that suggest a burr in the chamber or something like that? I don’t see hard extraction marks (or any marks at all) on the case rims.
 
gas valve is off...… is why I suggested stickin the drill rod in the gas cylinder hole . if it goes in, the valve is open. If it does not, the valve is either closed or misaligned with the barrel port.
 
The brass is supposed to have enough elasticity that it springs out and seals the chamber under pressure, and springs back enough to create clearance to be extracted without too much effort. At least under conditions of normal pressure. Hopefully the extraction problem disappears when you operate the gas system with every shot. I've only ever had the situation you describe, of stuck brass, after firing, and I didn't really count, 40-50 shots rapidly in succession at a pin shoot. Seemed like when the gun got hot enough, a round stuck. I'm speculating here, but maybe the pressure went too high when the chamber got really hot and heat soaked into the as yet unfired next cartridge. It's never happened to me again, but I've never put the gun through that sort of conditions since.
 
Sorry for the late response. Thanks for the replies, it definitely was the gas valve being shut off, newb mistake on my end..
That being said the issue with the casings remains. It ejects them fine now but I’m still not able to load them back into the chamber but from what I gather in the last post this is normal?

Yes...thats why we resize brass when reloading...especially the autos
