Well, the board is either fixed, or it's going to run terribly. Cross your fingers and hope for the best. I'm at my technical limit right now.

Eddystone fixer upper

#1 Post by echo1 » Wed Oct 04, 2017 12:19 pm

Hi Fellas

Running my post count up.

I had a guy on another board accept my offer on an M1917 Eddystone sporter. Fortunately, no permanent alterations were done to the metal, just the wood. What was done, was done by a skilled craftsman of the era, '50s - '60. Anyway, I had been on a hunt for the right M1917 for a few years, as I had acquired a complete stock set as part of a bundle in an estate liquidation. So when it's all said and done I'll have me a fine rifle for well under the market value. PAX

Mine's a 50s-60s sporter as well. Nicely done and was only $150. They put new sights on it but at that price I really didn't care about that.

This one was salvageable and was returned to as issued. The trickiest part was the FSB. I have another sport job, 03-A3 Smith Corona, that I thought was a Griffin & Howe, it was done so nicely. I took pictures and emailed the to the G&H historian. He was kind enough to send back comparisons pictures of the differences. Like your, was at the LGS listed as milsurp $200 bucks. Swoop. PAX

I bought one from the local Cabelas but it keyholed every freakin round. Since the barrel has 5 grooves, I had to tap the lead weight through then wrap a piece of aluminum around the lead and subtract the aluminum thickness to get the bore diameter. Just in case you want to slug your bore I thought I could share how I did it since it took me a while to figure it out.

Not surprised to read about the keyholeing. For some reason these rifles are bored/rifled on the loose side. A long bullet with a flat base can "pick up the slack", so to speak. I have had the best results with Federal 220 gr. s.p. in the blue box.

Nah, when I slugged the bore it ran at .311 so I make my own wildcat rounds. I open up .30-06 brass and stuff a .311 bullet in there. My wildcat .311-06 rounds. The 1917 is accurate with those rounds though and no signs of over-pressure or anything on the brass.

I shoot 220 grain Sierras in mine and it does much better. I tried 150 and 180 grain Spitzers and they didn't group well. After I read that some m1917 barrels have a too generous throat and shoot better with longer flat based bullets, I gave it a try. My first time out with my 220gr reloads I got 1.25 MOA average groups. I even had a couple 1 inch ones, so some of the problem might have been the loose nut behind the trigger. :^) I think I might even shave that down if I experiment with different powders an/or loads.

Yep, this is what I discovered. The Federal loads are posted at 2400 f.p.s. , if that is any help. You are definitely on the right track.

I'm guessing the .30-06 ball, with the exposed base, would expand like a Minie bullet to fill the bore. Since the rifles were originally made as pattern 14's for .303 British ammo, probably the original barrel tooling was used at least for early production.
