How much additional length is generally needed for reliable feeding?

I have lengthened the magazine by thinning the back and front walls.
Thinning is slightly tapered so as to not weaken the slots for the floorplate.

At approx. the half depth of the magazine, the length is 3.330"
At the very top, it is 3.340".

OAL on the 25-06 is 3.250" so I think I should be good to go.





The action is one of the "FAMAGE 1957" that has the front ring notched for 30-06 on stripper clips. Was marked '.30' on the rear ring, but I filed that out.

You should be fine. Since you thinned the front make sure the transition to the feed ramp is still smooth.

Paul,

Thanks. I suspected as much, but haven't thinned a guard like this.

For lack of a better explanation, there is still a small 'gap' from the front of the magazine box to the feed ramp. Without that, I would not have thinned the front of the magazine.

You just want the bottom edge of the feed ramp to be flush or in front of the interior front edge of the box. If the box is taken too far and the ramp not adjusted then you can hang a bullet tip.

That is what I was attempting to describe.

We're good to go!

I don't have a stock (or ammo) for this action so it will probably be months until I get to test it.

I've been told that one needs 0.020" to 0.030" clearance in a mauser mag to make up for cartridge cant. More than that can be a bonus if it allows you to play with longer seating depth.

I was just wondering as I have an action marked 30 on the receiver. I took that to be that the action was made for a 30-06 cartridge. If that is so, would one need to do anything to the magazine box for a 25-06 cartridge?

My Famage already had alterations to the box and feed rails. Many were altered from 7x57 receivers if my memory is correct.

If a magazine and action are set up for a 20-06 with a OAL of 3.34 then the 25-06 using the same case but an OAL of 3.25 will work just fine.

That is the kind of number I was wondering about. I suspected it was something in this range, but couldn't find it 'in print' in any of my books or online.

If the magazine is original to the action, a quick check of the length would confirm.

In my case, this action came to me completely bare. Not even an ejector box installed. Condition is perfect, not a speck of rust so I reassembled it with parts from my stash. Lapped a K98 bolt (handle already installed) and added bottom metal. That is why I had to lengthen.
