If you get the urge to build a kit, you might check out Jim Chambers' guns. I believe the site is www.flintlocks.com. By the way, that's a good looking hack you've got there on your signature! Is it a /2?
as said above, he has BEST if you want to spend money .
me, i would look for T/C HAWKINS IN A 54 CAL USED.
new they run about 599/699 ..THEY HAVE GREAT WARRANTY, FOR LIFE.
.45 is just a little too light for deer,.50 cal is great for deer and .54 cal is for everything, bear/etc.
.50 cal you can get supplies the most LOCALLY.
.45/54 are harder to get supplies AT YOUR LOCAL STORES.
me, only gun i like is a T/C HAWKINS.
2ND HAND PRICES ARE AROUND THE 250 RANGE FOR HAWKINS.
