Everyone has their likes/dislikes but IMO conicals are a PITA to deal with. Tried them a few times in both 36 and 44 caliber Colts. Didn't like conicals due to the PITA tendency of them tipping when loading and inserting into the front of the chambers, nor saw any better accuracy. Round balls work for me and the shooting I do with a percussion revolver. Same goes for spending time and the PITA of rolling paper cartridges for percussion revolvers. In fact IMO loading with the lever is part of the fun in shooting a percussion revolver.
For hunting large game and/or defensive work there are way way better alternatives than an underpowered percussion revolver. One may get a shot that is effective, but the odds are stacked against ya in large four legged game or two legged if you are counting on a capper for defense. Approaching 53 years of black powder shooting revolvers and rifles, 21 years of past law enforcement, and around 61 years hunting. Just didn't take it up last year. There is a certain lure to the romanticism with percussion revolvers or single shot pistols in doing as 'they' did it back in the days before modern firearms evolved, but those same firearms of old have their limitations.
