So I am very slowly buying parts i need to build a muzzleloader. I am not going for a period correct muzzleloader. More of a hunting piece that has traditional parts. So I am making a hawkens style. I have a stock (maple), barrel and breech. I want to make it flintlock so I can use it during our traditional season. My question is how do you determine the lock size? I plan on buying a lock and trigger within the next week or 2. My plan is to go with a set trigger setup.
