I just purchased a new Model 7 Youth Rifle (7mm-08) for my daughter and have run into a problem trying to open the bolt after firing a round. Let my try to explain what I am finding:

1: I am using Remington Core Lockt cartridges

2: When placing a live round into the chamber, the bolt works properly, even when ejecting the round. Also the live round will freely fall out of the chamber with gravity, when the barrel is pointed up and the bolt is open.

3: Once a round is fired, the bolt is very hard to open, especially when first trying to pull up on it.

4: After one round is fired and another live round is installed, the same as step two is observed of the new live round.

5: But in a side test, when I place a spent casing in the chamber, it does not fall out with gravity (like a live round does), and the bolt is hard to open and close.

6: I am seeing no unusual markings on the casings after they are fired.

7: At first I thought this only happened on the first round when fired, but it happens every time, some sticking worse than others.

Apparently the casing is expanding when fired, but almost like it is expanding too much. has anybody heard of this in Remington Core Lokts? I have used them for years in other calibers, but never had a problem with them. Any chance there is a problem with the rifle rather than the rounds? I plan to try shooting Federals or Winchesters to compare them, but should I be considering something else being the problem???

I'd try some different ammo first.

Sounds like it may be a rough chamber.

Hopefully, you thoroughly cleaned the chamber and barrel prior to firing?

Okay, problem solved. I obviously had a bad box of ammo. I shot some Winchesters and tried a second box of Remingtons and they all shot fine and the bolt worked with ease after each round was fired. Out of all the years I have ever shot Remingtons, I have never had a bad round, say nothing about a bad box. Thank you for your responses and may everyone shoot straight this upcoming hunting season....

Please contact Remington and give them the lot number off your box of ammunition. This is the only way they have of learning they screwed up and need to do a recall. They will likely ask you to return any you have left. You may well get some free ammo out of it.

Dear Sir;
Nick is right on.. I've never encountered it except with improper handloads!
It's a sign that your headspace is good and solid (you're sure the Remingtons weren't handloads).
But - I want to be sure as mentioned that you cleaned the barrel and chamber before you fired the new gun?
Did the Remingtons have a little round circle mark on the head? If it did you were getting high pressure - inspect that box of "bad" Remingtons and make sure they're weren't handloads. It's also possible there was a fine rust coating in the chamber that got "worn off" when firing those first few rounds
