Darrell Posted June 17, 2021 Share Posted June 17, 2021 I tested Precision Delta 124 JHP's today with the BR-5 powder I got in (36#) and was very impressed. Best group 10 shots ransom rest 25 yd in CZ TSO 1.09". 5.4 gr powder 1.100 OAL, CCI primer and Winchester cases. .378 crimp. Power factor 138 avg vel 1114 fps. I will upload a new revision of my spreadsheet next week after I test to other bullets 124 FMJ, 115 coated, 135 coated, and 147 FMJ and coated. Then work on .40 and .45.
