Luckily my FFL understands the problem. I showed them that it was in fact a cap and ball revolver and they chose to waive their transfer fee. They just receive the package and as long as I show them that it is not a cartridge conversion or a cartridge revolver and is within the law on my end, they waive the fee and are willing to be the addressee. I realize not all FFLs will do that.
As soon as the 8" of April snow melts I'll go shoot mine.
