I get a good chuckle out of this subject.
Went to the range with a buddy of mine a few weeks ago. I brought a flinter, he brought an Omega.
We talked about muzzleloaders for awhile, I asked him if he ever tried actual blackpowder before- his reply was that he had no interest because the cleanup was too involved, he shoots triple seven. I asked him how he cleaned that up, he replied that he ran hot water down the bore followed by a solvent scrub to get rid of the sabot fouling.
On shooting, all he cared about was velocity. He wanted to put them 3 big 50 gr pellets in every time to get that bullet out to the 100 yard stop as fast as it could. I urged him to try 2 pellets instead of one, but he insisted that it would have been a waste of 2 pellets because it wouldn't give him the maximum velocity he strived for. After about a dozen shots, he was all done because the recoil was giving him a massive case of the flinches. I was shooting my flinter with 80 gr of FFg offhand better than he was shooting from the bench, and I bet I spent less time cleaning when I got home than he did.
