it's ALL about personal choices and the primary use of the firearm. if hunting is some part of the equation, fit in the caliber and manoeuvrability factors. most folks who are somewhat like me enjoy a bit of each era, from the F&I war to the rev to the golden age and then the mountain man period. then there's the ignition system choices. i prefer flintlocks and enjoy early smoothies (F&I/rev), the golden era rifles and those rare half stock hawkens. if re-enactment is yer game, the firearm may need to be lots more period/era specific. if just shooting is the game, there are a few "hawken style" rifles that can be had for $500, but for the more specific era arm the price tag can escalate rapidly, particularly if a smoothie is needed. it's all good, there are no rules, totally subjective. enjoy!!!
