Got a ROA coming Fri. June 3 that I bought from Impact. Would like some advice on working up a load. Currently I plan on using .457 round balls and Pyrodex "P" with No. 10 caps. I understand I will need to seal each chamber either with a wad or grease - how do I do this and which is best. How am I gonna seal with a wad ? Looking forward to playing with this new toy. I shoot BP long gun but never before e revolver. Thanks.
