I'm Not Quite Sure Where To Post This, So Here It Goes.......i Am A Firearms Collector(handgun To Class Iii) Looking For A 1" Bullet Mold. I Have A 1934 Hotchkiss Ground Cannon (anti-tank Gun) That Fires 25mm (1") Ammo. As This Ammo Is Difficult To Obtain And M6 Powder Difficult To Obtain, I Am Going To Try And Fire Black Powder From The Gun Using The 25mm Brass Cases Fired By A Shotgun Primer. I Need To Be Able To Case 1" Bullets For The Round. Any Help Is Appreciated.
