I liked my 42 in barrel kentucky style rifle , it is 45 caliber . I also owned a 50 and 58 hawkens rifles , but dident use them very much I liked the long rifle better and killed most of my deer with it. I built it from parts I bought from gun stores . I killed deer up to 100 yds ok. I used a Small Siler lock on it they are the best locks for that style rifle, it never failed me for 40 years use...
