I started out a very long time ago in the mid 70s. I bought a CVA 45 cal pistol. it went off at best 50% of the time, I later found out the hammer and nipple were misaligned. my next gun was a CVA Kentucky 45 cal cap lock, it was OK, but still failed a lot, probably also a misalignment, but I sold it quickly and bought the same gun only in flint. that maslin lock was cheap, had a small delay but went bang every time as long as I kept the touch hole clean and wiped the frizzen and bottom of the flint. I moved up to the mountain rifle, in flint, with the same results, but now I had a 50. a few years later I saw a flinter in a store closing out and picked up an ultra-hi .69 cal smoothie, oct to round for $50. it was dead reliable, and I hunted with it for a long time, because after I got my deer and or elk, I could take some grouse for camp meat. then I bought a navy arms 3 band Enfield! that rifle was the bomb, I could reach out a LONG ways and it anchored anything I aimed at. after more than a dozen 250 ea tins of musket caps, it has never misfired.
that changed my opinion of percussion, so I purchased a CVA mountain in 50 cal percussion. it was reliable, but still misfired on occasion. since, I have had a lot of smokepoles follow me home and I have built a few and replaced that Maslin flint lock with a RPL from L&R partially because the old lock was starting to show its age, and partially because I found a deep love for L&R locks. now that I am older and wiser (at least I hope) I hunt with a .45 cal Lancaster flinter that I built and target shoot with a .54 cal mountain percussion that I completely went through. the reason I exclusively hunt with Flinters is when its cold, getting the cap on the nipple is a royal pain, a the capper is not easy in low light or cold (old eyes). they are all able to be made reliable, but as with any advancement, you have to trade off something to get something jeeps are nice, but horses will go where no jeep can,
you gotta put gas in a jeep, horses can graze. an advancement usually means the "upgrade' is generally better, but things are given up. in my opinion, using a cap lock for hunting is giving up too much. and to this day, I still carry a smoothie along when hunting, grouse are still tasty!
