    Posted: July 21 2014 at 10:35am
I have a Savage No. 4 Mk 1* rifle I bought several years ago. I was told it was new old stock and it looked it. It was heavily covered in grease and apart from a few stock dings, it looked unused. It has always had a feeding problem, or rather several feeding problems, which may be related.

The first round in the magazine (seated on the right) is usually overridden by the bolt. It seats like this in the magazine:


And in the rifle:


The second round into the magazine (on the left) usually pops out from the rear lip so it is faces nose down, with the bullet still held in the left front feed lip and the rim hanging in midair in the middle. In this case it won't chamber at all as the bolt face plows the nose of the round into the feed ramp at too great an angle. With the magazine removed the rounds on the right often pop out completely.





The magazine itself wobbles front-to-back, maybe 1/32 of an inch. It also has some play up and down. If it is seated fully back and up, the first round will feed, barely. Otherwise the round is overridden. The magazine is very tight side to side in the well. The gap in front of the trigger is how much play there is:


Any idea what's wrong here? I understand feed lips can be adjusted but there are so many things going on I have no idea where to start. Do I need a new magazine?

I am no expert here and I am going thru some feeding challenges as well with my #4 as well,,, However,,, It seems like you have nothing to lose by tweaking on the mag a little to see if you can get it to work.  The alternative is a new $50 mag if you can find a decent one.
 
It looks to me like your mag is bowed out a little too much on the left side which is causing the left hand round to pop out.  I don't have this problem as fine feeds perfectly off the left side. Mine also has strait sides.  I would try 'JUDICIOUSLY" squeezing the mag closed in a vise until the sides were flat fore and aft and parallel with the sides of the follower.
 
My mag has a hard time picking up the last round on the right as well.  The follower doesn't push the rear of the cartridge up high enough for the bolt to pick it up.  If you bump it sometimes it will snap into position. I deburred and polished everything in that area but no success. Also Rounds feeding from the right side are a little sticky, and noticeably different than the ones coming off the left which is smooth as glass. The only way it will feed off the right is to work the bolt smartly which is how these guns were designed in the first place, but shouldn't be required for normal operation.
 
I also would welcome some input form the masters on this problem.

First, I say Randy is dead on when he said the magazine case is bowed. It looks bowed out on both sides to me. Second, when there is a problem catching the last round it can be feed lip issues or a weak platform spring. First straighten that magazine case a bit and adjust the feed lips afterward. Then move on to the second problem. That's my advice anyway.

I'm in agreement with the bowed mag, but I think there's a bit more to the tale.
First remove the bow.
If the first (last) round is still looking like that then the right front feed lip is too closed & needs a gentle opening to direct a Mk7 ball round to a spot 1/2 way up & 1/3 off center on the feed ramp.
Then we'll worry about the left side feed if there is still a problem.

I would like to know how it got "bowed" in the first place.
I've never seen one before..& can't figure out how it could happen.
Is this an ORIGINAL magazine, or an aftermarket?

It looks original to me the aftermarket ones have sharper corners.
The most common cause of bowing a mag is smacking it home to make sure its seated fully. Each time it gives a hair  & all those hairs add up.

Something that was strongly discouraged by army types, if I recall correctly, by a lot of shouting.

Its more a bunch of medium whacks. Some do get carried away & really belt the thing though.
