Very Interesting ! I have never shot bowling pin matches . I remember reading about some Louisiana State Troopers were at a match ( during the 70's) . They were shoooting model 19's (357) with 6" barrels . Their load was the Elmer Keith 173 gr cast bullet sitting on top of 7.0 grs of Unique . The author stated that bowling pins were flying everywhere . I have found that load to be a great " general purpose " load . But like I said , I have no experience with it at a bowling pin match , just what I read . Regards , Paul
