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.

Agreed, looks like the scope base drill and tap is causing issues.

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.

sounds like someone used a hammer drill with a mile long bit to drill and tap that scope mount.

Sorry for your luck, hope everything works out.

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.

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.

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

Or decided that they "knew better" and #6 screws simply weren't big enough.

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. (http://www.pcb.com/AD_Explosive_Pressure_Conformal.asp) 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.

The barrel is threaded into the receiver until the headspace is correct and then locked down with a jam nut. Just like a Savage, since they are the same action.

That's why this is so hard to grasp. Hole through the receiver...OK. But to go completely through the barrel into the chamber... that took some doing.

Along with this..... this sight-in session before big game seasons, at our gun club range. A guy had a new scope mounted on his Remington 700 ADL rifle, '60 cartridge, he did the mounting. When he was ready to start shooting , he couldn't get the bolt to go into battery, hmmmm, "It always did before I put this scope on!" He'd done the same thing, drilled into the chamber, screw was too long, end of the bolt head was hitting the screw !! He didn't get it sighted in either!!

You can actually have the screws too long on a Remington or Savage keeping the bolt from moving without drilling into the chamber or the barrel.

It stretched when you fired it.

And every time you fire it it the longer headspaced barrel from the first time you used it, and use it again, it stretched some more.

I was simply stating a fact and not making a judgement on the merits of the method. As I stated, I have/use go/no-go gauges.

Sorry to have kept you guys waiting this whole time. I haven't shot it anymore. I bought it new at Bi-Mart in Vancouver WA. I took the scope bases off and sure enough there is a hole that goes straight through. I am going to SHOT show Monday and will ask Savage about it there. I have no idea what could have happened maybe I got a defect but I cant imagine this being like this from the factory. I would guess an employee or something did this at Bi-Mart.

rcmodel
January 12, 2013, 12:26 PM
You can bet Savage didn't do it.

Actions are drilled and tapped for mounts during manufacture, well before they ever get to the barrel installing department.

The real mystery is why anyone would have been drilling a hole that was already drilled at the factory in the first place??

I would be talking to management at Bi-mart. Sounds like it is their fault.

Probably had an employee cross-thread a base mount, screwed up the threads, and their in-house bubbasmith said "Hey Y'all, I can fix that!"

EDIT: At least you have your eyes/hands intact.

I wouldn't want to have my face anywhere near that if you fired it WITHOUT a scope base on it. 50k psi gasses exhausting a few inches in front of your face wouldn't be much fun.

Ifishsum
January 12, 2013, 01:26 PM
I've been to a lot of Bi-Mart stores - hard to believe that they would have done any drilling on it, at most they might have attached bases to existing holes. I could be wrong of course...

I'm betting it would certainly flip your hat off!

I had a case head fail on a 270 once and the gasses blowing out of the vent hole knocked stuff off the bench next to me. I can imagine the same force as a vertical geyser in front of your face is something you wouldn't want to experience twice..
