    So I recently acquired a K31 and bought dies for it. I know the original bullet weight for the military round was 174 grains, and Berger makes a .308, VLD bullet in 174 gr. I thought it would be fun to at least try and replicate the round somewhat, and I could always use them in my 30-06.

    I started poking around and cannot find a load for a 174 gr. bullet (which of course I realize doesn't mean there isn't one). So what you do you when you have a bullet that you'd like to use that's not in one of your manuals? I'm too new at this to punt.

    I would use load data for a 175/178 gr bullet.

    You could
    1) use data for a 175gr projectile
    2) call the projectile vendor and get their suggestions

    Not only do you not have data for the bullet you want to use, you don't know the dimensions of your bore, you don't know the dimensions of your chamber, and you don't know the amount of freebore in the throat of your barrel.

    In other words, you don't know a lot of stuff that can affect pressure in the finished round. So, you follow good handloading procedures and pick a load for the next lighter bullet and BEGIN WITH THE STARTING LOAD rather than the maximum one. You proceed from there to work up to a velocity that approaches what you need to get your work done. Checking all along the way for signs of overpressure.

    use data for a 175 grainer since it is a difference of less than 1% in weight

    best thing to do is get ahold of technical support for the bullet maker. each bullet has its own characteristics and one bullet shape/weight wont the same as another maker's/weight.

    I know more than you're giving me credit for, but I appreciate the help with my bullet weight question regardless.

    I think I'm going to give Berger a call on this one. Thanks for the advice.
