I just bought a brand new in the box model 700 ss in 375 ultra mag. I love it. Here is my problem. When one round is in the gun it extracts fine. Put two or three rounds in, and they will not extract all the way. Anybody else have this problem? I plan on taking it back tomorrow am.

Do you mean extract or eject.



It is not uncommon for Rem 700s in 375 H&H to leave an extracted loaded round on the follower and when the magazine has cartridges in it. When it occurs it is usually when the bolt is pulled back very quickly.

Ejection is the problem when two or more rounds are in the magazine. It will not eject no matter how slow I do it.

Is it leaving the cartridge on the magazine follower.

I will describe what happens with 375 H&H and see if this fits what is happening with your rifle.

When you pull the bolt back on a loaded round the extra length of the 375 H&H means the bolt head goes back further into the rear receiver ring before the projectile has cleared the front receiver ring. In other words if it was a 7mm Rem which is much shorter the bolt has not gone into the rear receiver ring by the time the 7mm Rem projectile has cleared the front receiver ring.

What then happens is that the rear of the case hits the inside of the rear receiver ring and then falls back on the follower. Model 70 375s have the rear receiver ring altered to allow for this problem.

Mike375, that is exactly what it is doing. I checked it with some fired shells and they ejected fine. They where a little rough going in though.

I don't know what or who fixes the problem but I do know it can be fixed.

I had a Rem 700 in 416 Remington when that calibre was first introduced. The rifle was called Safari or some similar name and they were fairly expensive, at the time they were a bith dearer than a Model 70 375.

That rifle ejected loaded rounds perfectly. It has since been rebarreled to 375 and a mate of min eownes the rifle. It ejects loaded 375s perfectly.

One difference I did note to other Rem 700s in 7mm Rem and similar is the follower protrudes up. In other words the bolt has to press the follower down when there is no cartridges in the magazine, whereas in other other Rems 700s in 7mm Mag the follower is under the bolt. In other words moving the bolt backwards and forwards is the same whether the floor plate is opened or closed.

I guess a gunsmith could recontour the inside of the rear receiver ring like the M70s in 375.

Maybe it is not worth worrying about unless you are swimming with crocodiles and your ammo gets wet and one does not go off

Need to mill the rear receiver bridge back and put a little "funnel" inside the rear bridge. Then you have to drill and tap another screw hole for the front screw of the rear base, and either modify the existing rear scope base or obtain a blank with no screw holes and drill/counterbore correctly. (this is why the long 375 H&H length M70's have a .330" rear screw hole spacing for the rear scope base).

Here is a photo of milling the rear bridge on a Standard length M70 to make it into a 375 H&H length, same process for the M700 Rem. I use a different setup with a different fixture for a M700 due to the round bottom receiver.

Personally, I would box it up and send it back to Remington, totally unacceptable as a finished product, or just ask for your money back.

Mike -

I agree. After all it is far safer and easier on the ammo to drop the floor plate to get unfired ammo out anyway. In my safety classes I discourage working ANY action to extract fired ammo when there is an alternative.
