Less moisture concerns with Blackhorn -- noticeably less bore fouling -- no more breechplug grease -- far less stink and smoke at ignition - far less corrosion worries. All the other Blackhorn attributes really doesn't affect me, (for instance) 10-20 shots without swabbing-thing. I dry swab Blackhorn after every 2nd shot and never shoot more than several shots without a wet patch of 91% alcohol in a small spray bottle.

So I do believe I've been converted! Blackhorn's minor annoyances are the need for moderate force to load my 50/40 sabot bullets and the dry crust the power generates inside the breechplug flash channel.
