If you want lots of info and places to buy slugs for 12,16,20,28 etc., goto Accurate Reloading, http://forums.[blank]/, and contact Ed Hubel, 12 gafromHell. He's into Paradox big time.

I'm just about to order another mold from Accurate Molds...a 0.690" dia, 700-715 gr tumble lubed slug for use with a WAA12F114 wad. Should get 14-1700 fs depending on which shotgun I use...low speed for O/U's and hi speed in my NEF USH.

I just received my designed #51-690B from Accurate Molds, for use in my 50-70, 50-90 and 50 Rigby wildcat.

You can also get slugs from BPI, Ballistics Products, http://www.ballisticproducts.com/, and several other online places...just Google "12 ga slugs".

I would stick with 600-750 gr slugs as the recoil goes up fast as you increase slug weight and the performance does down just as fast because the recoil is so vicious at the heavier end you won't load them up high enough to gain anything other than recoil.
