Hope to get a "faux" No5 or similar style up and running this year.

The CZ mags also come in 7.62 x 39 (if you can find them).

I had a tinker with 10-round Ruger Mini-14 mags, but the spring is designed for autos. Chopping turns off the spring is not the way to go. You need to wind a spring to the same overall design and length, but with thinner music wires

Anyone thought of doing a 6mm PPC or 6.5 Grendel on a No4 action? Same head size as 7.62 x 39.
A bit off topic, but I made a 7.62x39 conversion too, Around a CZ527 mag again:
