I took my new rem 700 .308 out yesterday and shot a couple boxes of hornady superformance 178 grain... It was ok, but not great.

I had an issue with the edge of the bullet case (neck edge) catching on the sharp edge of the recoil lug or barrel edge? once it actually bent the neck edge so much that I couldn't close the bolt? Had to throw that bullet away.

It only happens when I lay the bullet into the action and slowly shut the bolt until it catches, then its stuck on that edge hard? I have to back off the bolt move the bullet with my finger and try again.

So bought a different type of bullet on way home (federal 150 grain soft point) just to test at home and those don't seem to catch as bad. In fact only maybe 1/2 the time?

Is this something that I should be concerned about? if I cycle 4 rounds though the internal mag I see a tiny brass line that is being marked onto the cases.

The groups were a bit all over the place at 100 yards, when I got home I realized that the stock/action screws were only torqued to 39 inch pounds... my understanding is the pillers in the Hogue stock should be 60-65 inch pounds. I tool the action and barrel out , cleaned it all up, looked at the stock and it seems to show a little rubbing, I re seated the action and dropped a few times to set the recoil lug , then torqued the screws to 60 inch pounds. I will try again Sunday at the range. I got some 168 grain hornady amax superformance (they seem to be longer than the 178 grain and the bolt is tight to close) and the cheap fed 150 soft points. Ill update after the sunday shoot.

But whats with the deal with the catching of the neck lips?
 
Normally rounds don't feed well if they are laying on top of the follower but out of the magazine... when loading one round at the shooting bench, flip it into the chamber with a finger or set it into the magazine and feed from there.

There are single shot followers available that sit in the magazine on top of the follower and make single feeding very easy.
 
hmmm, I've never heard of this. My vanguard loaded slick like that at the range. Its case was totally different (270 wsm) which has the neck a lot more raised into the chamber I suppose. thanks....
 
I've had this before where the gunsmith has cut the chamber, but not rounded the edge to allow a smooth feed - both factory and reloads. It's a simple fix to round the edge (fine/medium grit sandpaper), but best done with the barrel removed so that you can get at it properly.
 
I'm interested. 145 people read the thread but only a couple comments. Is it because this is common knowledge and I'm just catching up, or no one other than scout has seen this before? Is this something I should call Remington about. I.e Warranty.
 
Might have alot to do with Remington quality nowadays.Nutnfancy did a video awhile back where his 700 in 300 Win Mag had a brutaly stiff bolt lift/pull due to a burr in the chamber.

You might need to polish the chamber area out with a Dremell,that is if you feel confident enough to do so.

It has nothing to do with quality. 700's and many other bolt actions are designed to feed out of the magazine. If a cartridge is simply placed in the action, the angle at which the bullet approaches the rear of the barrel and the chamber is incorrect for smooth feeding. Often the bullet will contact a flat and not go into the chamber. If the cartridge had been fed from the magazine, the bullet would be angled up and into the chamber.

That is why a company makes single shot adapters that fit in the top of the magazine, on top of the original follower. They allow a cartridge to be simply placed there, the back of the shell will drop lower, the shoulder will be held higher... the bolt will advance it smoothly into the chamber.
