Please help!

I bought a replacement barrel. GM 20" fluted.
There is some problems with it (or may be not?)

1. A cartridge does not go easy all way in.

As you can see on the pic it is going free to the shown point, then has some kind of resistance. I need to pish it in if load it manually. Shure bolt does get it in with no problem though.

2. But it does not extruct unfired cartridge. The cartridge is kinda getting stuck.

Is it normal? What's happening?

My stock target barrel gets the cartridge all the way in with no any resistance.

Here are a couple of comments

1. Well first off; your picture does not seem to be working.

2. Did you give it a good clean before you started shooting it? If not you will find it will have comoline, and other crud in the bore, which will effect its reliability as far as feeding/ejecting goes.

3. A GM barrel has a Bentz chamber; this is much tighter than your stock 10/22 barrel, but not as tight as a bolt action match reamer.

4. You will most likely find a note on the side of hte barrel reading. "Live rounds may not eject". So if they don't eject, then that is normal. Sometimes live cartridges eject on my GM barrel sometimes not, it depends on what type of ammo and how clean the barrel is.

5. Make sure you are not using CCI stinger ammo. They have a longer casing then other cartridges and will not feed in the bentz chamber; they will be dangerous to shoot.

6. It may be a big hard to get the cartridge all the way in, but not to hard. If you have a round in the clip, and you hold back on the bolt and "slam" it forward, the round should go into the chamber. I would not try this at home, only at the range.

Thanks, Jordan.

I did not fire it yet, just tried to get the cartrige in. Looks like bolt should not have any problem to push it in.

Well, if it is normal, then I should just tried it in the range, see what happens.
 
If it does not feed well, try breaking it in with a brick of dirty powder hard bullet high velocity ammo, like federal thunderbolt.
