    VV N-133 in .30-06 200 gr. CB load

    I was fooling with this powder in the .223, and looking up the burn rate it appears to be close to win748 and 3031. My favorite cartridge is .30-06. Also, I had a can full of 311299 200grain cbís, which unfortunately filled up from a roof leak before I noticed it. When I dumped the water out, the bullets had white lead oxide or carbonate or whatever it is, and brown iron rust on them. I didnít want to handle them that way, so I let them dry out and then tumbled them in Lee liquid alox. The idea was to keep them usable, but keep the lead salts off my hands. That worked well. So, hereís the upshot (pardon the pun) of todayís range session:
    Load - 28.0 gr N-133. 311299 200 gr GC sized .309, alox lube, WLRM primer.
    Estimated 1700 FPS.
    Win M70 LH SS - 5 in 3.3 inches @ 100 yards. 4x scope.
    Savage M112 LH SS - 5 in 2.55 inches @ 100 yards. 10x scope.
    All in all, Iím pleased with with it, and loaded up 2 more boxes to try in other rifles. I did buy an 8 pound keg of the N-133 which no one wanted, at the L G S.

    Tried the load above in a Springfield I have had for 65 years. Flaigs rebarrelled it for me with a 26” target barrel and Lyman sights. (I was 16 then, had some money for working on a truck farm.) The 5-shot group at 100 yd was 4.4”, a sign of discontent for this rifle for sure, even though the results from the two stainless rifles were not so bad.

    I'd try a different powder/load. This was the first group I fired with 311299's out of my .308 Savage 12.

    I don't think the water would have done that much damage to the bullets.

    The 311299 200 gr / 28.0 gr N-133 is fairly snappy in the bolt actions, so I tried it in the M1 Garand. Shooting at 25 yards, so as to see what sight changes I would need for longer ranges, it showed it had not enough steam to function - I had two failures to eject, one barely ejected but failed to feed, and two misfires. Still, the 3-shot group was 0.7”, so I think the test showed that the load could be tweaked to work. I will increase the charge to 33 gr and change the primer from WLRM to Federal. I have never really tried to develop a cast bullet load for the M1.
    I did shoot a clip of hardball after, to make sure the rifle was functioning properly.

    That seems consistent. 0.7x4=2.8" at 100yd. Not bad for an M1.

    I have yet to try cast in my M1. I may have to after I get my .308 tweaked.

    FWIW, I tried faster loads with the 311299 in the .308 and it did not like them. I will go back to the 1800-1900fps loads.

    OK, here’s the results of tweaking the load for the M1. By the way, i shot the two misfires from the last test in the M70, fired OK and hit where they should at 100 yd.
    The load is 311299 200 gr GC, 33.5 gr N-133 (Vihta-Vuori), and the Federal Gold Medal 210 Match primer. I had no failures to feed, eject, or fire in an 8-round clip - the only difference was the “ping” of the clip ejecting was not nearly as noticeable.
    I fired 3 at 25 yd, to see about sight setting. The group was 1.9”, two of the two of the shots noticeably tipped. I came up 4 clicks (from the 100 yd FMJ setting) and fired a 5-shot group at 100 yd. It measured 7.35”.
    This load in the M70 measured 4.3”.
    I think this is on the edge of what can be done with the particular alloy of these bullets, which is a mixture of range scrap and wheel weights. I have never had super CB results fot the M1, so I’ll quit for now with this. N-133 does seem to work much like 3031 or 748.
