Alright guys so been a long time hunter with a 7mm rem mag. Decided earlier this year to upgrade to a NEW 7mm rem. Well, I just got back from the range and I’m having a big issue. I was only able to shoot 2 rounds. The first shell got stuck after the shot. So I forced the bolt open and figured it was just a bad round. Until, it happened again! Except this time I couldn’t get the bolt open and had to head home to bang it open with a mallet. I live about 45 minutes from the nearest range so this obviously ticked me off. And this wasn’t cheap ammo, it’s Barnes TSX, which I tried a shell from each box. Pictures below is the spent case.

Can you post a pic of the ammo head stamp and the case? And a pic of the rifle caliber stamp?
 
It's a Remington. They went bankrupt for a good reason. Their "Quality" Control was shipping everything out the door, and if the customer caught their errors, which were many, they would offer some sort of warranty. I gave up on Remington rifles long ago after along list of complaints. Good luck with that one.
 
Was the bolt hard to close on either round? Did you try loading and shooting these rounds in your old rifle? There is obviously a problem some where. It sounds like you thought you were shooting factory rounds, could they possibly been reloads?

I shot rounds from the same box of ammo in my other rifle, shot fine dropped a bear at 100 yards with it. I bought the ammo at a gun show, figured it to be factory. Bolt was not hard to close, and when I got home I cleaned it and cycled every 7mm round I own and it was fine.

Yeah not my first Remington issue, maybe I’ll go back to Winchester.
 
Those marks are exactly where the brass swells ahead of the belt in my experience. I use the Larry Willis collet to reform the belted mags I reload and it is in that area that it affects. So, I don't know if the chamber needs to be cleaned up from some.sort of machining marks or deburred or what. You would think that if it was pressure the expansion would be more uniform, or other signs. Just a thought.
 
If there's a gunsmith local, have him check the headspace. IIRC, there is no warranty repair on rifles manufactured pre-bankruptcy.
 
I have had a browning SS in 7mag since 1994. It’s made two safaris and taken well over 100 white tails here in sc and if the Lord tarries an eik next October …it’s left handed. A left handed friend borrowed it for a bear and moose hunt in Canada and a similar thing happened. There was a small area of rust nearly invisible to the naked eye as the casing went into chamber. Cleaned that area and it’s still a shooter. But a new rifle might be gone for me…
 
I had exactly the same issue with an Accuracy International / Remington Defense .300 Win Mag Mark 13 civilian clone.

As infuriating as it is in a new rifle7MAG (I was furious too), this is not the end of the world. The marks on your brass indicate that the rear edge of the chamber has not been properly deburred. Most likely, the finishing reamer was not run through the chamber after it was cut with the reamer. If you decide to keep the rifle, or cannot return it for whatever reason, any gunsmith can run a finishing reamer in the chamber in 3 minutes and fix the issue.

PS: since on the Rem 700 the bolt handle is brazed on the bolt body, you want to check that banging it with a mallet did not crack the solder. It has happened...

Hello, My wife and I hunted with Marius 2 years ago. He fit us into his schedule after a different outfitter "bailed" on us. He was always very good with communications and although we didn't end up meeting him personally, he called us multiple times during our hunt to make sure things were going well. We were very happy with him.

Reach out to the guys at Epic Outdoors.

They will steer you right for landowner tags and outfitters that have them.

I have held a membership with them for years and they are an invaluable resource.

Way better that asking random people on the internet...WAY better

Skydiver386,

Did you ever find your 30-06 CZ550? I own a fairly solid conditioned one, if you wanted to talk.
