  • does the Barnaul 762x39 123gr SP work ? not unless you hit bone ...

    3 , 1Gal (16.5" thick total) water jugs @100M - passed through all with some little splash and a small amount of damage . the bullet buryed deep into the softsand behind and was recovered expanded (.50 x .60 cal frontal), then the core fell out of the jacket . the small entrance hole in the third jug was a "CAUGHT-CHA" give-a-way .

    4 , 1Gal (22" total)water jugs @100M , through all 4 , bullet recovered . looks like one of them Long Flat Nose cast bullets for handguns . just a flattened tip . STILL buryed itself in the sand but no expansion .

    in both testshots the jugs were hit near dead center . entrance holes in the last jug told the story , SLIGHTLY raggy .30cal . no bullet particals in the lightly damaged jugs at all .

    unfired _____________ through 22"water into softsand (4" to 5")

    0.870" _______LOA _______0.730"
    0.114" _______tip ________0.200"

    when this test was conducted with W-W 30-30 150 and 170 grn SPs , W-W/Fed/R-P 762x39 SPs - classic expansion w/some fragments . the Ulyanovsk 8M3 HP - compleat fragmentation .

    against 2 LEGGED targets @100M , expect point-on-no expansion penetration from the Barny SP unless bone is hit . my test standard is ,,, if it dont do nothin hitting 5.5" of water , it likly will do nothing else hitting flesh .

    for deerhunting , if you can hold to the point of the shoulder or shoulderblade , it should give good expansion /penetration through bone .

    20.5" barrel , 50deg F. sunny w/thin wispy clouds measured @15ft.

    1) , error . indicated
    2) , 2109fps error . indicated
    (installed sun screens)
    3) , 2436
    4) , 2430
    5) , 2390
    6) , 2447
    7) , 2441
    8) , 2441
    9) , 2452
    10 , 2449

    AVE, 2435fps @15ft.(hit the waterjugs at ~2060fps , 1160ft.lbs.)
    ES , , 62fps (without error shots)
    corrected too MV = 2453 ave.

    it sure aint gonna expand @100M from an AK .
    i'll try the water jugs @50M next time and chrono it again for an errorfree reading.

    Remember reading some place that Russian hunters tend toward FMJ stuff. Less meat damage, one or two small holes in the pelt: hunting for business.
    Maybe in Siberia, like in Inuit country, small cartridges are used for large animals and they go for all the penetration they can get.

      hi MartinS .

      well i suppose this Barny 123grn SP would do more than a pointy M43 PS FMJ bullet . the tip flatteneds right down too .200" and there was some blowout of all 3 and all 4 waterjugs spraying water 6 to 8 feet . with M43 PS the jugs just stand there and weep except sometimes the 4th jug catches it sideways and is blown .

      with the other SPs and HPs listed above , Wolf FMJ, milsurp M67 and US67 FMJ ,,, the jugs are destroyed . i tryed putting pressed paperboard between the jugs to catch a bullet 'profile snapshot' but even with Wolf FMJ, M67 and US67 , a 4" to 5" hole is blown in it.

        50M , 3 water jugs (16.5"). jug 1 and 2 blown (kinda) but #3 just weeping ?? recoverd the empty jacket in a fine looking mushoomed condition from jug 3 but the core , apparently flying like a swooping frisbee by then , sliced through in the front and out the side with little distubance . very minor flecks of lead in the first jug . i take these to be what lead is poking out ahead of the jacket that splats on impact - then shears off .

        100M , simulated shoulderblade (3/4" dense , partical board . dont laugh , it fractures similar to what ive seen in photos for bone) in front of 3 water jugs . like the other 100M shots , through that and all and into the sandberm but a more explosive effect on the jugs . the jacket curled back to the base clinging to a small piece of lead , on top of the sand in a shallow divot . only in this test did i find any real lead bulletfrags and only in the first jug (21grns worth) .

        this bullet is bustup or nothing and nothing comes at 100M even with robust muzzel velocity (for 762x39) . the jacket and core wont stay together when it does expand wether a little or a lot . none of the other REAL SoftPoints act like this .

        i suppose what i'm saying is that the Barny 123grn SP is , well , its cheap

        at least now you know for sure .

          Yep...Russian hunters do prefer FMJ to that of HP... but they do like Soft Point as well. Takes quite a bit for the Russian 7.62x39mm HP to mushroom...
