ysrracer Posted January 7, 2020 Share Posted January 7, 2020 I chrono'd some 9mm rounds today. Winchester White Box 115gr, and Federal Red Box 115gr. I used my Para P18.9 Pro Custom with a five inch barrel. The WWB averaged 1230 for a power factor of 141. Fastest of 8 rounds 1255, slowest 1182. The FRB averaged 1190 for a power factor of 136. Fastest of 8 rounds 1199, slowest 1180. It's pretty consistent. Link to comment Share on other sites More sharing options...
