Remington 700 SPS problem...

I just bought a left handed Remington 700 SPS 7mm mag. I cleaned the rifle before I even thought about shooting it. Took it out to the range to fire a couple rounds through it.

I shot one round and I couldn't pull the bolt back. i had to use my rubber coated handle on my stapler to beat the bolt back. i figured it was just because it was a new gun. well i shot 2 more rounds and each round i had to beat the bolt back. I put the rifle back in the truck after that.

Can somebody tell me what the deal is on why i cant pull the bolt back..?? I can cycle new ammo through it with no problems but as soon as I shoot it I cant extract the empty brass. This is factory loaded ammo also.
 
I had a similar problem with a Marlin 30-30 lever gun once. Not on every shot, but every so often I could not budge the lever after firing. I tried to figure out why but never found any reason in the action. Finally I tried inserting and extracting an empty cartridge casing that had jammed. I it was very difficult to get into the chamber or out.

It seemed to me that the brass had just expanded too much. I had been shooting PRVI 30-30 so I tried something else. I never had another jam with federal or remington 30-30.

First thought is excess pressure. Are you familiar with the signs, flattened primers, cratering around the firing pin indentation, or shinny spots on the head of the case? Try a couple rounds from a different brand of factory ammo. If one sticks it is the rifle. Be careful about hammering on the bolt that you do not damage the scope. I jammed the power adjustment ring that way with a rubber coated umbrella handle. Burris was kind enough to fix it.
 
I'd like to see pictures of the brass, sides and base showing the primer. I agree it's probably way too high pressure but then maybe not. Hard to tell without seeing the brass.

I just help my boss build a load for his same rifle. What I did notice, as some here have lead to already. That baby has one very tight chamber. As one said-Try to rechamber a shot round and see if it is stilll sticky.
 
Either a chamber out of spec, or ammo too hot. Possibly a combination of both. If the chamber is cut to close tolerances you will get more pressure from any ammo. Combine that with ammo loaded on the hot side and you could get sticky extraction. Might want to try another brand of ammo.
 
I tried remington core-lokt 150 gr ammo. I have a box of Winchester to try. I will try and post pics of the brass later tonite.
 
I would be curious to see what it would do with some GO AND NO-GO gauges as far as checking HEAD SPACE. My guess is the HEAD SPACE maybe a little on the tight side.
 
I had this same issue once with a 700 SPS Varmint in .308.

We were shooting 7.62X51 CBC ammo out of it and the cases were expanding and sticking. All of us ended up with bruised hands that day because it was so difficult to extract. It's only ever done it with that ammo.
 
I Think I figured out how to post pics.. Hoping you can help with my problem.

Are you first uploading them on a photo hosting website like photobucket then copy and paste the image URL over here on TFL? The icon to the left of the quote icon that looks like a envolope with some mountains on the bottom click on that then you can past the image URL that you copied from a photo hosting website.
 
Hmmm--I'd say the odds have gone up on headspacing being the problem--especially since it's a belted magnum case and it headspaces off the belt.

I'm just guessing--but it looks to me like those case rings are showing showing abnormal expansion in the case head/web region. I would very carefully measure the cases with before and after fired ammo to see if everything is in compliance--that way you can figure whether or not ammo is potentially the problem.

Either way, I'd be very cautious about using the gun any further--a case rupture at the head/web with that magnum power could make for a very bad day.:eek: My less than 2 cents.
 
I would take the gun and the cases to the nearest Remington service center, or back to where you bought it, and have them look at it. It's hard to tell from the pictures but it does appear to be a headspace/chamber issue.
