Rem. 760 Gamemaster - cartridge ejection problem

I picked up a Remington 760 Gamemaster (circa. 1976) about a year ago and outfitted it with a Leupold VX-1 4-12.

I finally got to shoot it a few days ago and I love the way this gun shoots. The gun is extremely accurate at 50yds (<0.50" groups).

My problem is that on more than one occasion at the range, after firing a cartridge, it took several 'pumps' to remove the spent cartridge. Eventually it would 'catch' and be ejected. This didn't happen after every shot, maybe one in every four shots or so - but I don't want it to happen at all.

I have a buddy of mine that had the same issue with his 760 a few years ago and I wanted to know what the proper method of correcting this issue is. I want to use this rifle on the deer opener, but if I have to take it to a good gunsmith - that's fine too.

I'd appreciate any feedback.

Have gun, will travel.

The first thing I would do is disassemble the gun completely, giving it a good cleaning and lube, and looking for anything that doesn't look right, especially in the cartage carry area.

If this doesn't fix it, it's off to a gun smith.

I've only seen this happen with handloads. Are you shooting factory ammo?

Re: Rem. 760 Gamemaster - cartridge ejection problem

I had something similar happen to mine a few years ago. My problem ended up being that from teh sling being attached to the front of the forened, it had slightly bent part spring in under the forend. The spring would allow to much play when I would try to eject a spent cartridged, and I had to work like heck to get the casing out. I end up taking mine to a gunsmith, who fixed the problem and have since to a barrel band on for the slind. Not sure if this is your problem or not, but you may want to look into it.

Sounds like an extractor problem. Could be as simple as using a toothbrush to clean the face of the bolt and extractor claw.

Is the slide not coming back at all. If you wait 30 seconds or so does it work OK. If reloads it is easy to reload to hot for a pump, that will work fine in a bolt.

Re: Rem. 760 Gamemaster - cartridge ejection problem

Thanks for the info. I'm shooting factory loads (Winchester X 180 grain).

I don't have a sling on it, but I assume there was one on prior.

My thought is the extractor. The slide works flawlessly.

Re: Rem. 760 Gamemaster - cartridge ejection problem

Have the extractor checked by a gunsmith. I had the same problem about 20 years ago with mine. It was a cheap fix back then, only a few dollars. Like Pappybear said, try a thorough cleaning first and see if that helps. I wouldn't wait long, the season is fast approaching and gunshops will be getting flooded with guys who only use their gun a couple times a year, bringing them in for problems.

This. I alwayts full-length sized for my buddy when I reloaded round for his "PA Tommy Gun".

To the OP. You say "accurate at 50 yards". If you plan on shooting ANY further, you NEED to get to the range and see what she'll do at 100 yards. At 50, 1/2" groups are nothing to brag about to be honest and even a rifle with mediocher accuracy (as these guns are known for) should almost punch the same hole that close. Also, if you plan on shooting to and beyond 100 yards ethically, and can only shoot at 50 yards, your rounds should be grouping about 1/2"-1' BELOW your point of aim, depending on how high you have the scope mounted above the bore. If they are centered or hitting high, you will be shooting way over the bullseye at 100-200 yards if you plan on shooting that far in the first place.

Re: Rem. 760 Gamemaster - cartridge ejection problem

Roughly 6-8" high at 100 yards in most cases has been my experience when zeroed at 50 yards....even with my 444 and it's got rainbow trajectory!

You really under estimated the ramifications of the boondoggle you have just perpetrated!
