Russian SKS / Re: Regarding very early 1950 Tulas
« Last post by jstin2 on Today at 10:43:50 PM »
On Canadian Gun Nutz forum under my 1950 entry a 1950 was posted with pictures. It has the engraved date, hand stamped Tula star and eyelet latch cover. It doesn't have a 90 degree gas port or spike bayonet. But it shows early a 1950 transition.  It has a refurb mark and painted, but it should help in showing how the carbine changed in 1950.

Often wondered how .32acp or .32 H&R Mag bullets would work in light loads.. They are .312 which I wouldn't think would cause a huge pressure issue. I have seen someone, Berrys or Hornady has a 100gr/110gr .311 bullet. And I have seen some load the .303 Brit 174gr bullet in the x39 case....must be a heck of drop on that.

 :)) I've wondered the same thing about .32 cal bullets. I wouldn't be too concerned about the thousandth of an inch.

However, loading that long 174gr bullet would cause me some concern, or at least questions I'd want answered first. Would you have to load it deep to avoid having 0.000" to the leade? If so, what does that deep loading do to the initial pressure inside the case? Perhaps not much if you have to decrease your powder load for decreased case capacity. Would you need a slightly slower deflagration rate on your powder?  think1

Bob posted a few pictures on CGN , but also stated that it has a sloped gas port not a 90(looked at it and compared). It definitely has a engraved date, hand stamped Tula star and eyelet latch pin.

The options for 西 are:

Xining 西宁市 in Qinghai
Xi'an 西安市 in Shaanxi
and Xichang 西昌市 in Sichuan.

Of the three, I'd guess it would be Xi'an as Shaanxi a is a well known SKS fabrication location. 



We certainly need another (better) stamp image to narrow it down between 西 and

very difficult to tell which one the character actually represents (without knowing the arsenal history or the official arsenal codes).

That's the reason for my original guess of Siping as it's the only one I was able to find in the northeast portion of the country. All the others have been found in the NE provinces: Jilin, Heilongjiang, & Liaoning. We haven't seen them sprout up from other areas like Hunan, Siuchan, Chongqing, etc.  dntknw1

I favor Siping as being consistent with the Northeast China region. The fact that it's apparently a partial stamp or unfortunate lighting accident in the photo, makes me reticent to throw out the restriction to the three provinces of Northeast China.

In fact, I've been pondering whether the D in DB or DP stands for Northeast, in other words, Dōngběi in Pinyin. Can't come up with anything reasonable for B or P, unless DB means Dōngběi and DP means something else. It'd probably help a lot if I knew Mandarin  :)) Maybe pcke2000 has some ideas.

In the map below the DB cities are surrounded by green dashes and the DP by red. I made this map before the Siping proposal.



I've mentioned before that I'm not in favor of the Destination Bangladesh or Pakistan hypothesis, with my counter-argument summed up as, why English abbreviations?

Welcome!

I'd be interested to hear the results of your hand loading. Although SKSs and AKs were never intended to be match shooters it would be interesting to see what they could do from very tight specification ammo, like Lapua or handloads.  I have had 3" groups and nearly had sub-2" groups (if it wasn't for a "flyer"  :)) ) from cheap commercial steel case ammo in my Romanian at 100 yds.

Nearly all of the military or commercially manufactured ammunition for 7.62x39 rifles is 122-125gr, except for the 154gr soft points from Tulammo. All of the bullets are advertised as .310 or more rarely .311 diameter, again in the 123gr range except for a Barnes MPG lead-free frangible bullet at 108 gr. Reloading options are rather limited in regard to bullet choice.

I've always used 00buck  pellets for slugging a .30 cal bore.

forgot about other rifles chambered for 7.62x39.... that explains the extra expander ball.

I checked the twist as you said... it's right there.. 9.45.

As far as slugging.. I've done it but using the right slug, not a fishing weight, commercial ones, would be best. Thanks for your input.

Measures .312

Welcome.. thumb1

The number I've seen quoted for years, says the twist rate is 9.45, you can check and verify with a tight fitting patch and cleaning rod. Count the number of times the rod turns in relation to the length it travels. Typically the SKS share the .310/.311 bore with the Ak-47, .303 Brit, Mosin, and 7.7 Japanese.

The different expander ball may be for a .308 dia bullet, which you could find early Ruger Mini 30s had a 7.62x39 chamber, but a regular .308 bore. If your that gungho on accuracy, slugging the bore would be the only way to truly find exactly which size bullet would work best. This method is commonly used on Mosins or Enfields and reloading for accuracy, due to the slight variance in Finnish Mosin bore sizes, some can be tight like a .308, others might take the regular .310 bullet, and some really worn Russian/Enfield bores can exceed .312. Directions for bore slugging can be found pretty easy.
