I have been upgrading by replacing my factory rifles with custom builds. I am now down to just two, the .40 Lancaster and the 54 Hawken. One of those will cover any application I can come up with. To complement those I have the .20 gauge Chief's grade trade gun from NorthStar West, and a Navy Arms 12 ga double barrel. I am good to go for the flintlock era of the percussion.
