This new rifle won't feed 220 gr subsonic Remington ammo at all. All the rounds tip up and jam into the barrel face. Tried a modified follower spring and smoothing the feed lips. No help. 5.56 rounds feed effortlessly. The 300 rounds leave the mag late and tip up at a sharp angle. Viewing the feed lips from below seems to indicate the taper is way to far forward, delaying release of the round. It looks like they just used a .223 receiver and mag hoping the 300 would feed. Anybody else have any suggestions to get it to feed? Thanks, Bob | ||

Yes, Remingtons use one size fits all receivers; so the feeding is controlled by the stamped sheet metal magazine box; remove it and bend the feed lips until it works. | |||

I ended up putting an HS precision straight feed clip in my Rem 7 that had exactly the same problems. | |||

There is a way to cheat feed death with blunt bullets or bullets that hit high on the breech face in the 700. Remington certainly wouldn't approve, but you can put a heavy, 45 degree feed cone on the face of the bolt nose recess. That bolt nose recess is only there to protect you in the event that you want to do something silly like blow up the gun. You still need to leave a little bit of the recess or the bullets will stove pipe on the chamber face. Removing to much can make it feed even worse so it's a cut and try affair.

On this version the receiver has rails with feed lips machined in like a Mauser. The sheet metal box merely contains the rounds. I've never seen that either.

Yes, upper left is where the bullet noses are jamming. That looks like a fix.

The cut is actually made all the way around Bobster. The barrel is spun off and simply held in the chuck of the lathe or preferably, set up on centers and run in a steady rest and make the cut with either a boring bar or form cutter. Care has to be taken to NOT take to much. You still need to deflect the round enough that it won't stove up on the chamber face. I have made this cut quite often in 700s chambered for the 375 H&H and the 458 Winchester to keep blunt nosed bullets from stopping against the barrel face. I have also done it quite regularly to 700s that are run with single shot followers that don't use the feed rails to guide the cartridge in. When I was a kid. I had the stick. I had the rock. And I had the mud puddle. I am as adept with them today, as I was back then. Lets see today's kids say that about their IPods, IPads and XBoxes in 45 years! Rod Henrickson | |||

10-4 that. Looks like a semi-coned breech. Mauser must have done a helluva lot of testing to get the reliable feed they did with a flat breech! I think this is just a case of Remington cheaping out by trying to shoehorn a 300 BO into a .223 magazine. Some work and some don't. in our case the difference is just 2 mm shy of feeding.

If you have access to new springs if something goes horrifically wrong. You could try reducing the magazine spring tension a bit with some light bending. That some times helps when the 223s don't feed. When I was a kid. I had the stick. I had the rock. And I had the mud puddle. I am as adept with them today, as I was back then.
