    I got some chronograph data this week for some Yugo M67. 10 rounds were fired out of each rifle with the chronograph 10' from the muzzle.

    SLR107FR (16.3" barrel)
    Average: 2253fps
    SD: 12.5

    AES-10B (RPKlone w/ 23.2" barrel)
    Average: 2411fps
    SD: 10.7

    I'm wondering if anyone has a good value for ballistic coefficient for the Yugo M67?

    I'm kinda expecting it to be alittle better than M43 as the lead core makes it more dense. OTOH, it's a flat base bullet vs the boattail M43. BSW

    I think it's about .3-.31 but I'm only guessing based on comparable size bullets from Sierra and Hornady.

    Is it just me or are those SD's quite good?

    That could be the reason I got a 2MOA group out of the SKS last summer.

    For right now I'm using a BC of .298 from Federal's .312 cal 124gr lead core FMJ as being close to the M67 slug.
