..............This is kind of a followup to the 35 Remington post. This is another of the 1894 Brazilian small ring Mauser actions. Numrich/GPC offers a kit consisting of the barrel, magazine blocker, follower and follower spring for the large or small ring Mausers. At the time I bought mine they were $99. Obviously the top photo is the complete rifle. The stock was from Boyds.
In the middle photo are the normally visible things I did to the action. Basicly just polished and jeweled the bolt, then blued the extractor, extractor band and the lug area of the bolt head. Also added the Williams receiver sight. The front sight is a Lyman 17A that sits in a ramp I made using a piece of keystock. I filed it to shape and filed in the dovetail. The rear facing slope is serrated and I used a thread chasing file to do that.
In the bottom photo are shown the internal mods made to the action. The mag filler block supplied, is a piece of nylon shaped to fit between the rails. There was a problem with it moving under recoil and tying up the follower. I drilled and countersunk a hole through the rear of the magazine housing and ran in a 1" drywall screw and that was that. The follower they supplied was a black plastic piece and the follower spring was a longish oval coil. It appears there are some mag bodies out there missing these 2 items.
Did the follower and spring work? Yes it did and it is setup for the cartridge. Did I like it? No I didn't. I took the original one and cut it down and then had to fab up a deal to hold the coil spring on the underside. Since the original was designed for the .473" casehead OD, I had to solder in the brass piece seen in the photo to further bias the case to the right. Those rounds on the left were fine as-was.
Then I made an extension for the ejector. The 7.62x39 is short compared to the 7x57. The ejector is under the rear bridge sufficiently far that the 30 Rooski Shortski case would usually rebound off the side of the bridge, to lie cattywhumpus across the rounds in the magazine. Hard to see in the photo but I cut away part of the guide rib in the left action wall, then cut the slit in the left wall the ejector normally resides in, forward. I took a nondescript bit of metal and MiG welded it to the front of the regular ejector, and contoured it with the Dremel.
To back up a bit, when I got the stuff from Numrich I was not really impressed. First of all the barrel looked like it was contoured by 2 guys. One at each end of the barrel working toward the middle. Further, the bore was rough looking. It looked like they'd used the reamer a few times too many and the grooves also had sideways marks (chatter?). I managed to get the outside of the barrel cleaned up, and decided what the heck, and screwed the fully chambered barrel on.
The barrel breeched up so tight that the little numbers "7.62x39" that had been stamped there (maybe 1/16" tall) caused the face of the left locking lug to drag, so I stoned the face back till it didn't. I'm VERY happy to report that regardless the appearance of the barrel's bore, it's a shooting essobee. Never had a leading issue and accuracy is just great.
A few targets. All these were fired with the iron sights, issue trigger at 50 yards. Visually inspected boolits sized .309" Javalina lube, Hornady GC's. Cases used were Winchester, K-P, and PMC, with Winchester primers. Powder charges were thrown.
