TOW will sell you GOEX in 25lb. lots @ $11.02 per lb. including shipping and hazmat fees. The Maine Powder House will sell Elephant brand in 25 lb. lots @ $8.76 per lb including all fees. UPS delivers it right to your door.
If you shoot a lot, this is definitely the way to go. 25 lbs. of 777 will run you $500.00 against $218.00 for Elephant or $276.00 for GOEX. Savings
of this magnitude, especially if spread over a group of shooters, are definitely worthwhile. Of course, if you subscribe to the belief that real BP
is difficult to clean up after, 777 and the other artificial powders may seem like a bargain. The most important thing to have when cleaning C&B
revolvers is a good set of gunsmith's screwdrivers- the parallel ground kind. Colt and Remington revolvers are so easy to take apart and reassemble that I always completely disassemble them for cleaning after a shooting session. Since crud buildup in the lock work is a prime cause of wear and failure in these guns, I'm not sure that avoiding a full strip down and cleaning is a good idea even when using artificial powders. You will still get material blown into the mechanism, and cause problems, even if it doesn't cause rust. The hand spring is particularly vulnerable.
