Mannyspd1, did you get that b gun in 2010 or 2011 on the round barrel run? Bill and another guy I know as well as myself all ordered b- guns on that run. Bill had a curiosity that continually led him to finding answers for his questions and he was not afraid to do so. He told me that like the original business 45-2.1" he ordered his with a 1 in 20 twist. At the time 1 in 18 was std and no small amount are spec'ed 1 in 16. Bill wanted the 1 in 20 original twist to work with 400 gr bullets like the originals. Bill was a big fan of the penetrating and killing power of the Lyman Gov't 500+ grain round nose bullet but wanted to experience original weight bullets. The curiosity factor right there. Bill was a wealth of knowledge we've all lost. Mb
