    I have 200 once fired (not from my gun)remington .308 win. brass. Ihave full lenght resize, trim, debur flash hole and ultra sonic cleaned. I whould like to fire form this brass to my gun's chamber. Hodgdon reloading manual list 14.0 gr. of Trail Boss behind a 150 Nosler BT. for 27,100 PSI.

    Is this enough pressure to fire form the Remington brass?
    Can a cheaper lead bullet be used?

    Thanks Tom

    If you are going to use bullets to fire form I would personally load them up and try to get some useful data and practice in along the way. Then all the fine tuning can be done with brass that is formed to your chamber.

    Why are you fireforming to your gun? Are you concerned about big tolerance differences or just looking to squeeze the very most in accuracy out of your setup?

    Looking to squeeze every bit out of my setup. I just installed a leupold 6.5-20x50 LR/T TMR on my Remington 700 5R.

    I have some friends that are pretty good shooters, it's time they start paying for lunch.:D

    like one has already said load and just shoot,thats if the resized case will chamber in your rifel without trouble of any kind.and with a 5R I would go with a 168gn or the 175gn class bullet.the 5R just loves either one and has a lot of info to back it up.I know I have one,and love the 175gn bullets out of mine.even keeping them to SAAMI specs really works for the 5R.

    hint 44gn's of varget works for many with the 175gn bullet.and a COAL of 2.800:D

    Johnboy,
    Try 43.2 of IMR4064
    R-P neck size brass trimmed 2.008" (using Lee neck sizer)
    SMK 175
    2.233" ogive
    CCI BR-2 primer

    .5" five shot group at 100 yds.
    1.8" five shot group at 300 yds.

    And that was with my hunting scope, can't wait to try my Leupold Mark 4
