I'd like to have one of my pre-64 M70s re-barreled for the swift, but the cost of magazine box, short follower, etc. is high. SO, what is needed to accomplish this using a FN commercial action? And if that too is so costly, what about the .22-250 in the same actions? Who here has done these and how tough has the feeding issue been? thanks

Not an FN, but I had a custom 22-250 barrel installed on tang safety Ruger that was originally chambered for 25/06Rem. It feeds flawlessly without any magazine alterations. There were those who scoffed at the idea but if it works, it works.

You won't need anything; they will feed fine, even from your M70. Mag boxes are very forgiving except in extreme cases. Get it? Cases. Unintended joke.
I put all manner of short cases on long actions. Without issue. Usually.

I have an FN Mauser in 220 Swift. If you need pictures or any measurements let me know.

Jim: See my PM. thanks

Here are pictures of my magazine box, follower, etc.

The other magazine box is from a FN 30-06.

Very cool. Can you put the follower in the bottom of the magazine and stack three rounds in there and take a pic from the top? I’d love to see the orientation of the cases and the mag box sides/end.


That’s a factory rifle?

It will work without that spacer and short follower. And they didn't change the trigger guard/box dimensions. Just blocked it off.

thank you much Jim. Great detailed pictures !

"Can you put the follower in the bottom of the magazine and stack three rounds in there and take a pic from the top?"

The spring is inserted backwards and I would have to pry it out which I won't do because I'm sure I would break the spring and I doubt they are readily available. So I assembled the rifle and inserted 5 rounds in the magazine.

"That’s a factory rifle?"

The SN on the receiver matches the SN on the barrel (369xx). There's no markings on the trigger guard. The stock and trigger were replaced.

Understand re:the spring. Thanks for the additional pics. That’s a neat rifle.
