    what number would you choose for a 62-68 gr FB Bullet???

    I went with a .035 and it works well for BT Bullets but really isn't enough for FB
    .040 would be a good choice

    I wanted to add. If you were only shooting FB bullets with a conventional say 8 ogive you could easily go on up to .070

    The decision really needs to be driven by what bullet you plan to use

    I bought a near new Borden built 6PPC Rimrock BR LV that only had 47 rounds thru it. With every Borden built rifle, he includes a spec sheet detailing different details. In the FACTS ABOUT YOUR CHAMBER COLUMN: He said, your chamber was cut with a JGS reamer ground to .441 inch diameter at the .125 datum ahead of the boltface. The reamer and chamber have a .262 inch diameter neck, a 1 1/2 degree throat with a .2435 inch diameter freebore that is .030 inch long. Reamers of this dimension have been used to chamber many Championship and world record rifles. Cartridges used in this chamber should have a loaded neck diameter of .261 inch or less. I prefer to use a loaded neck diameter of .2605 inch. The chamber allows use of cases up to 1.505 inch long, trim length is 1.495" (or shorter.)

    I shoot fb 68 hillbillys and Barts ultras with 55 freebore. Works great. Haven't tried boat tails.

    A few possibilities:

    1. You're shooting some L-O-N-G bullets.
    2. You like a lot of jump.
    3. It's a 6PPC Weatherby.
    4. There's a zero missing. :)

    If I knew I was just going to shoot FB bullets, a 0.070" lead with a 1.500" case lenght works great! That length works good for most BT bullets on .825" jackets as well. With pointy BT´s on .790" jackets, its to long.

    People like to argue "ideal" lead lenghts, but forget (or fail to mention) that the specified case lenght have a big inpact as well. A 0.040" lead with a 1.525" case lengh puts the bullet in the same spot as a .065" lead with a 1.500" case... Simple math, but often overlooked.
