I would also describe myself as "satisfied."
I got in to this sport out of an interest in flintlocks. Over the past 3 years my knowledge has grown a lot. My respect, admiration and appreciation have grown tremendously for the people who once depended upon these weapons to defend themselves, their homes, put food on the table and win our independence.
I will always want to add new weapons to the collection. Who doesn't? But muzzle loading has been and continues to be very rewarding.
