Flint smoothbores are a tad more fun !!
For many years I've shot primarily original big bore rifled Jeagers in competition matches & for long range hunting mainly because I have a fetish for shooting tight groups.
That being said, I get more fun out of shooting the 20ga./.62 cal. French style smoothbore rifle I built & regulated the barrel to be dead-on
@50 yds. I've won several 50yd rifle matches with this smoothbore.
Folks I've observed who were having troubles with flint rifles & smoothbores needed their locks tuned, were not using the correct patch & ball combo or both.
Cleaning a flat breached smoothbore is much faster & simpler than a rifled gun with a flat faced breach scraper & a good bore cleaner.
As a former owner of a BP store I continue to use my all-time favorite formula patch lube & bore cleaner given to me about 40 years ago by an old timer at Friendship. I know many of you continue using the same.
The inexpensive 3-part formula is a 1/3rd mixture each of rubbing alcohol, Murphy's Oil Soap & hydrogen peroxide.
This mixture also makes a great hand & frizzen cleaner at the range
