I used to own a .50 Investarm Hawken and I loved it. this was many years ago and had to sell that rifle due to extenuating circumstances. Fast track to a month ago, My new wife recently indicated that she would love to get involved in The traditional percussion side of BP shooting. I found her a TC .50 caliber Hawken in great condition and found a .54 cal TC Hawken for myself. I'm now thinking that we should both be shooting the same caliber to simplify the amount of related gear needed. I'm wondering what advantages, if any, the .54 cal has over the .50 cal or vise versa. You help in this would be very much appreciated.
