Just purchased some 240 gr. semi wad cutters from Falcon bullets for my Super Blackhawk. I have been reloading a while but this is my first attempt with a semi wad cutter. My Buddy and best friend has reloaded these but Im sad to say he passed away two weeks ago, cancer, or he could of told me. Do I need any special seating die? Im using a single stage Lee press. It seems his were loaded under the top ring, but Im not that sure. I dont really see a crimp ring has a blue lube ring with a beveled base. Thanks for any advice. Ive experience with 200 and 225 gr. hard cast rnfp, but never these and of course all four of my manuals arent showing anything exactly like the ones i bought. I know to go by weight not style, just being careful. Thx in advance
