R700 feeding question

[ShoootA]

this is my first bolt action and I don't have a lot of experience with them, so forgive the noobness

I've attached a couple pics of what my r700 does to ammo when cycling ammo from the magazine. I have 3 different types of factory match ammo and it does it to all of them. Sometimes it seems like there's more resistance than should be when chanbering a new round, but I don't know what normal is.

Should I be concerned? Is it something I can address?

I'm the only owner, I bought it brand new but I changed the stock when I bought it. This was a couple years ago but I never addressed it til now

I want to start shooting it again and I want to start reloading for it as well so I want to get this squared away.

Thanks in advance!

did factory ammo cycle fine before you changed the stock? What stock did you install on the action?

If you are using an internal box magazine, be sure the magazine is installed in the proper direction and is centered in the bottom metal's grooves.

Or did you install a stock with removable magazines?

With marks like that on the case you should see galling where the round is catching up.

It's a bell and Carlson tactical medalist with internal mag and hinged floor plate. I honestly can't remember if I had the problem before changing the stock out. Horrible, I know. I wish I took care of it when I noticed it.

I will look into the mag when I get home. Could that cause the marks on the projectile as well?

Feeding from the mag internal or otherwise will cause scratches on the brass from the feed rails. That being said a bad follower and or spring can cause excessive issues with the ammo. Have someone that knows look at the rifle.

I tried to find some tarnished ammo to scratch up as an example. I hope the case scratches as pictured will put you at ease as this is normal.

However, the chatter on the bullet and case neck are not. When you get home make sure the magazine is installed correctly. there should be a cut out on the front end where the feed ramp is. If you cannot see/feel the cut out then your magazine may be upside down.

Thanks for the feedback so far!

I took pics of my internal mag box and it appears that it's installed correctly but I see indications of where there's rubbing. How much is normal, idk. I do have a friend that's very familiar with bolt actions, I'll have him take a look. I'm still concerned with how difficult it is to feed as well as the markings on the bullet. Sounds like the follower may be causing the issue

Your pics show brass transfer at top of ramp. Use a dry cotton Q-tip and rub it around the top of the ramp and rear of chamber opening. Maybe a burr causing the chatter and scratches. If it is a burr, it will grab the cotton of the Q-tip and leave fuzzies behind.

Also appears as if the top edge of ramp is a sharp edge. The mag lips hold the round "downward" against ramp during feeding, while the bolt face forces it forward. Scratching and chattering would result as brass is forced over a sharp edge.

Breech opening of chamber should have a very slight smooth chamfer. A burr or sharp edge there, will also mark the brass like you are experiencing.

A judicious stoning with a carborundum or Arkansas stone of proper shape should fix it.
