I bought a Stevens 200 in 22-250 and loaded some BRAND NEW Winchester brass with Winchester large rifle primer.
Before I get started with this I have another 22-250 (Howa 1500) and had no issues with it.

Today I loaded 5 cases with RL15 powder 33.8gns, 50gn vmax bullet COL 2.363
and 5 cases with IMR4895 36.5gns, 50gn Speer spitzer, COL 2.342

My first 5 with the RL15 had the circle marks on the case but made no hole in the side.
Next I used the IMR4895 I shot 3 rounds 1st had the mark on the side, the next 2 put a perfect circle hole in the side of the case. All of the rounds were very hard to open the bolt to eject spent case after each shot.

Any Ideas what may be going on? What is causing this?
there are no marks on the cases when shot through my Howa 1500 22-250

Looks like a defect in the chamber on the Stevens. Is there a scope mount above this part of the chamber? Its like they drilled too far into the receiver.

The scope base screw is poking through the chamber and when the case expands under pressure it cuts a hole through the wall like a hole punch.
 
Im guessing you bought this rifle used? Its pretty obvious that someone when putting a mount on it drilled through into the chamber. If you recently purchased this rifle you should be contacting the seller ASAP.
 
I would be taking that rifle back where you got it from. As well covered it sure looks like they well drilled into the barrel with the scope mounts. The cases with the small circles just developed less pressure and the marks you see in the circles are from the screw bases. This is not at all a good thing.

If the rifle were mine it would be getting returned to where it came from, with the cases showing what happened.

One hole to deep. :eek:
 
Under that scope mount screw you'll find lots of little brass discs. Eventually they'll fill in the gap and you won't get any more holes in your cases.

But I jest. Take it back where you got it.
 
Or JB Weld it! :what:

I've seen that recommended before!!

Yowser!!

Seriously though, on a 22-250, the only safe fix is a new barrel.

If it was a low pressure caliber you could plug screw it and recut the screw with a chamber reamer and it would probably hold.

Holy crap, that's REALLY bad. That gun needs rebarreled now thanks to Bubbasmith.
 
Jes wondering, what does the hole measure? It's definately from a hole in the chamber, but it looks a bit larger than a 6-48 screw...
 
As a side note.
These .223 cases came out of a copper-crusher pressure test barrel at the Remington factory.

I bought 1,000 once-fired Rem cases from a scrap dealer and found these 6 mixed in.

Probably were needlessly drilling the mounting holes out to #8 when they went into the chamber.
 
+1

Probably drilling it out bigger after they broke the tap off in the 6-48 hole and screwed up the threads geting it out.

A bud of mine built a Faux Marine Sniper 03. The gunsmith drilled the receiver holes too deep. Bud stopped shooting when the through hole appeared.

The barrel had to be replaced. So will yours. Sorry, this is dangerous.
 
Take a look at RC's cartridges and now take a look at these Charge Mode Conformal Ballistic Sensors. Note the "conformal". Pretty interesting stuff. In a few years when I retire it is something I plan to have time (and money) for. This method is one of several. I would also like to mount a strain gauge on a barrel and record some actual pressure curves. Simply for comparison purposes.

Your bud was a hell of a lot braver than I am. I would not wait for a through hole to stop shooting! :)

The ridiculous thing here is that they could have easily pulled the barrel off prior to drilling since it's secured with a barrel nut. The good news is that the OP can buy a barrel nut wrench and install a new barrel himself.

How do those Stevens actions headspace? I've never owned one.

I bought GO and NO-GO gauges from Midway for my 7mm-08 Rem (Savage WW) but some people simply use a fired case.
