Ok I admit I know a lot about modern military arms (at least those in America) but I am not well versed in antique arms from the 18 hundreds. So what is the difference between a Hawken 50 caliber kit and a Kentucky 50 caliber kit, say from Dixie or one of the other major suppliers. I am new to this and I have a Dixie 40 caliber from the early 50's but I'd like to upgrade to a larger (50 or 54 -58?) caliber and maybe I would like to try my hand at building one rather than just to buy one. Please, all help and advice is welcome. Plus anyone who want to take a newby out to help him learnt to shoot and care for these guns in SW Idaho, well I'm here and available most times.
