One Accurate K31 - AR15.COM

Posted: 12/20/2005 3:43:08 PM EDT

I have several K31s. One with the St Marie Diopter setup, most just as is.

But on this one I installed a Darrell's Scout Mount and Leupold FX IER 2.5x28 Scout scope for shooting in the open class of our clubs Milsurp Silhouette matches. And boy does it SHOOT!

After some practice on the silhouette range today (nailed 18 chickens in a row at 200 meters and 10 rams at 500 meters) I took it over to the 100 yard range to let some interested parties shoot it to see how they liked the scout scope. Bear in mind I had already shot over 100 rounds through it today already.

With only a front sandbag under the front, on the bench, I put 3 rounds down range while waiting for the others to come over. This rifle has consistently shot sub MOA 10 shot groups. But after these 3 rounds I stopped before I spoiled a thing of beauty. After subtracting the calliber, .308 - .125"group.

My load:
165 sierra GameKing SPBT
Graf brass TTL 2.175
Reloader 15 43.5 gr.
GM210M primer

I do love the accuracy of the K31. My favorite has produced this with a St. Marie clamp on mount, a full clip with 4 in the same hole. The other two were definately my fault, not the rifle. GP11 is pretty darn good surplus.

sweet! I've got 2 K31's and haven't shot either of them yet

Don't have the pics anymore, but I have a 10 shot group from a '34 K-31 that measured .687" center to center, shooting handloads.

Not shabby.

John, we need to meet up at ASC with the swiss rifles. I have the clamp on mount coming any day now, and a russian scope that should be here by next week, I'm pretty anxious to see what it can do.

another question.

How were they able to get these things so accurate with chrome-lined bores?

I haven't seen anything that says they are (chrome lined).

Mark,

My folks and I are heading to El Paso on Friday to do Xmas with my sister and her kids. I also have a AK build to dive into sometime soon. If we get weather like today after I get back then it definately will be range time.

sounds good, why don't you come to the Houston Crew full auto shoot on New Years Eve? A lot of cool toys will be there.

well I didn't guess they were either, but I read somewhere, might have been swissrifles.com or somewhere on here where they are. Do they not looked chrome-lined to you? If they're not chromed, the bore and the chamber shine like stainless steel...

Years ago my buddy got $25 from a pawn shop for one of those. I didnt know that mounts are available. Isnt ammo expensive? Are components available to reload? I always heard that those were accurate guns. SWEET GROUP.

Mounts are available from Brownells.

The ammo is pricey, but not insanely so. GP11 Surplus, which is really quite superb match ammo, is available from SOG, AIM, etc. Wolf, Hornady and PRVI make commercial 7.5 swiss now, and the Wolf is around $8.50 per 20, with boxer primed brass.

The components are available. The brass from commercial stuff can be used, or Grafs sells 7.5 swiss. RUAG and NORMA are out there too, but more expensive. And, you can resize .284Winchester to 7.5 with a full length die. The bullets are standard .308 bullets, so they are widely available.

where did you purchase your rifles? Aimsurplus?or is there a better source?

Posted: 12/21/2005 6:31:57 PM EDT

[#13]

I bought mine all from AIM over the last year and a half. I am up to 8 so far and here are the first 6 I received.

Noice!! I like the scope setup on that rifle. I have two myself (rifles, not mounts) and I have not shot either of them. I want to try to pick up about 200 rounds of the Wolf ammo, and use it for the brass to reload. I'll have to make note of your recipe and try it!

I have one I got from Big 5, but have not shot it yet. I too want to get the Wolf as it is reloadable. The stock on mine was pretty beat up and I thought I would try steaming up the dents and sanding it some to get it to look a little better. It didn't seem to help as the raised dents had some kind of black crap staining the wood pretty good. I tried to sand the stuff off, but it seem to go pretty deep into the wood grain, so I left them. I have started to coat it with tung oil and hope to get it all back together soon. I still need to order some ammo though!!!

Sheldon,

One of mine is a later ('53) rifle with a blonde stock. It was dirty and beat up like yours. I used Easy Off to strip it pretty well, and then steamed as many of the dents as I could out of it.... that didn't improve it too much, so I said screw it and sanded it. The stock crest is still very visible, as I was careful not to take too much wood off. There is a little 'overhang' at the buttplate, but the wood looks 500% better. It's a blonde beauty now.

Not to go too far off topic, but that is pretty clean!! Here's mine. I may try your method or use the TSP method if I get bored later, but for now I'm done!! I'm working on a stock for a Winchester 52D right now. I'm trying to wet sand it with tung oil and want to work up to 600 grit and see what it looks like. It looks pretty good now, but I have some way to go yet.

Here's the Winchester one.

Guys just to let you know, in case you haven't looked them up in a while, the St. Marie clamp on mounts are now $75 from brownells and I've heard $75 everywhere else they're sold. I got mine last week, and have a temp scope mounted on it now, waiting to hit the range this weekend, should also get a russian scope in the mail sometime this week, will post pics and range report(s).

I did some research on this some time ago and found that the bores are chrome-nickel steel. The Swiss tried Chrome-moly steel one year but didn't like it and went right back to Chrome-nickel.

So they aren't "chromed" per se. Still, they're close enough.

Thanks, that's good to know. That added with the fact that they were cleaning freaks and used non-corrosive primers has left us with some very impressive arms.
