I bought this .50 Hawkens about 12 years ago and started to shoot the .50 cal balls through it. I have only taken it out twice because I could not get anything on paper. Years later I’m looking at the barrel and notice that it is not a Hawkins barrel but a Green Mountain Long Range Hunter barrel and up on future research find out that it is a 1:28 twist and only conical bullets or sabots are to be used. Does not shoot ball well at all because of the faster twist rate. I have plenty of sabots, a box of TC Maxi Balls and plenty of Back powder to get you started. The Barrel alone is Worth $400. 1. Because they don’t make them anymore and 2. Hunters are using them out too 200 yards on Big Game. $700OBO You can text me at 661-556-6861
