Got to chrono a load of solo 1000 and 147gr PD FMJ @ 1.14 today. out of the 10 rounds the high/low was 844/894 for 869. 844 is just below the PF while the average would be at 127. this was done on a 65 degree day. With the 869 average,should i be concerned about not making Pf since it so close to the borderline? should i bump it up the 4.0,which is the next cavity in the Lee disk?
