like the last poster said , i to started out with a cap lock . that was back in the mid 70's. 1977 to be exsact .
that was the first rifle i ever built . in 1982 i jumped to a flintlock and have never looked back nor ever considered looking back .
my sugestion to you would be to find eather a local club or a group of local traditional shooters . link up with them , shoot some of their rifles .
if a flintlock is what you want , then yes it will be much faster to lern the ropes with the help of an exspereiance shooter . but again , the key to a flintlock is a quality lock . IMO its a must
