Hey guys, I am having some problems with correct feeding in a AICS short action I am trying out.

I have attached some pictures to give you a better understanding of my problem.

It is a 5 round AI mag, but also does the same thing with another short action mag. My rounds are a 6.5X47 Lapua with an overall length of 2.825

The rounds fit into the mags great. Plenty of room left over.


I put an AI mag in with say 5 rounds.

I shoot one round and then pull the bolt back to eject my spent case. Try to put another round in the chamber and it is getting stuck under the action feed ramp.

I am not sure why it would do this. The mag seats just fine and it clicks in with a positive click.

It is like something is not lined up right. You can see in one of the pictures that the actual action is sticking out in the mag well area.

Do I need to dremel some of my action away to get it to fee properly??? I hope not.

I see how the bullet tip is getting stuck on the feed ramp. It is after a round is pushed up in the chamber, then the next round is pushed up by the magazine spring. Well this next round is getting the tip of the bullet caught under the angle feed ramp of the action. Frustrating!!!!

Any, some help would be great. Thanks a bunch guys

This first picture is of the action sitting and hanging over the magwell area. Is this normal???, It happens on both my short actions.

This is the second round being chambered. After I enject the first spent case. This tip of the bullet is getting stuck under the action feed ramp.

This is the bullet after I pushed it down and to the rear of the mag. It then pops up just fine. This is what it should look like under normal circumstances. Round is now ready to be pushed by the bolt into the chamber.

Jake,

Have the spacers been removed from those mags? If you're trying to feed rounds from an AICS mag without spacers (or other mag of similar internal length) in an action that wasn't intended for such a long round you'll see exactly what you've got going on. The solution is to either use magazines with spacers to prevent the rounds from moving forward and catching the action, or relieve the feed ramp just a little bit to allow the tip of the bullet to pass without catching on anything.
 
Re: AISC feeding problems..

Is that a rem 700 action? I'll bet the relief cut on the stock rem is alittle short for the length of your mags. I have a few aics mags and they load well with a 130vld. But my defiance action might be cut alittle farther foward. I am guessing that might be the same bullet. You might give the guys on the gunsmithing section a shout as they will have a answer for you.
