What are you plans with this rifle??? Targets, small game or larger game??? Have you considered flintlock or percussion??? How much money do you want to put into this gun???

Take a look at www.flintlocks.com
These are considered the most accurate out there...

I used a .45 back in the 70s, now use both a .40 and a .54 caliber flintlock...

I tend to call them American Longrifles as they were made up and down the east coast during the 1700s and early to mid-1800s...
