Just finished this one up. Like many of my projects, it started out because I'm a sucker for orphan rifles. I saw it about a year ago in a local shop in the 'Used' rack....an Interarms Mark X in 30-06. It had a cheap synthetic stock on it but the bluing was nice and it clearly hadn't been shot much. These are commercial derivatives of the Mauser 98 and fairly well regarded. Anyway, it ended up coming home with me and I finally got time to get to it.
The trigger was a non-adjustable style. Gary @hdskip had a new adjustable factory trigger that he graciously donated to the project. The sear slot in the receiver needed to be elongated at the rear and given a squared off radius to clear the trigger top sear. After this pic, it was polished and hit with some cold blue.
The barrel was 24" with a bit of corrosion at the muzzle. The inside of the barrel cleaned up nicely and the rifling looks really good. I shortened the barrel 2" and gave it a fresh crown with a Manson piloted crowning tool. I ordered a Bell and Carlson Medalist stock and got after the bedding.
The stock is a good quality stock but needed some massaging of the aluminum bedding block to make everything fit.
For the bedding, I went off the reservation. Since the bedding block didn't have anything around the front action screw, I put a 5/8" pillar in the front and shortened the bottom metals goofy front 'stub'. The factory action screws are 1/4-22 with 55 degree threads. I experimented a bit with some scrap and found out that if I tapped a 1/4-22 thread, a 1/4-10 tap would completely clean up the 1/4-22 threads. Both action screw threads in the receiver were retapped 1/4-10. The top of the pillars were given a counter bore to provide clearance around the threaded cast in blobs. Button head cap screws were used and the head diameter reduced to .375" to fit in the bottom metals .400" flat bottomed recess. It shows .0025-.003 movement which is probably decent for a flexy flier receiver like this.
Into the ProBed and back out with this stone axe action jack. Bottom metal was bedded later.
It's 8 lbs/2 oz with an aluminum Weaver K6 and light-ish rings.
Everything fits and works. Fired three stout rounds for die setup.
Good shootin'
