    12SO CB Clone in a Rem. Hull, 7/8 oz. between 1330-1350fps. for Bunker with Fio. primer. What powder will get you there and keep the pressure 10,000 psi. or less?

    Promo or Red Dot. Perazzi Big Bore might have some real pressure/velocity data for you. I'd go around 19.0 - 19.5 grains. Should get you in the ball park.

    18.5gn of 700x is +1300 and less than 10,000psi.

    If you go to a different primer, Hodgdon has data for International Clays with that wad that is pretty low pressure.

    not to highjack the thread but I am new to re loading and trying to get the whole proper wad to hull thing. I though tthat the 12so was for straight wall hulls like federal, I though the remingtons were tapered. Please advise.

    thanks

    vpsr6,

    Generally, yes. Use straight-wall wads in straight-walled hulls, and tapered wads in tapered hulls.

    Most would recommend not using a tapered wad in a straight-walled hull, but some folks do this, and it works out OK.

    Using a straight-wall wad in a tapered hull is perfectly acceptable. I've used a Federal 12S0 in Remington hulls with pretty good success in the past. With Winchester primers, 16.8 grains of Clays and 7/8 ounces of shot, this is a very soft-recoiling load.

    Yes, 700X should make it happen - 12SO Wad, Rem. Hull, 18.5 grs. @9300 psi. @ 1325fps.

    Thanks for thoughts, would not have thought of IMR700X. Cannot wait to try and center the clay with this load and full choke.

    If you notice, the Federal 12S0 is usually a one ounce wad in a straight walled hull. It is basically a 7/8 ounce wad in a tapered hull, since it takes up more room in the smaller capacity hulls. I usually reserve straight walled wads for appropriate hulls and use Wads intended for Tapered hulls in tapered hulls. There are a few exceptions to this rule, like the Federal 12S0 for 7/8 ounce bunker loads. It's a tough wad and really holds up under the extra velocities required. I get some really great patterns with this wad at higher velocities.
