Hello all;
I was finally able to get to the range today after doing honeydo's for mom.
I could finally take the Crono and the batteries and all the other STUFF that takes 30 minutes to load, so here are the results with the group size at 100 yards.
100gr.SPBT 46.8gr. H4831 CCI-200 2.775 Over All Length.
Two 5 shot groups.
Lo= 3056 |3042
Hi= 3097 |3097
Av= 3079 |3069
Es= 40.67 |54.5
Sd= 15.62 |22.71
0.865"
55gr. Nosler purple tip
I was shooting two 5 shot groups in each powder weight, and some grouped better that others. This may look strange, but I would load up ten shells for each powder weight, then at the range I would shoot 5 of the ten, get the chrono results, then shoot the next five. I did that this time and the fellow two tables to my right was shooting a 7MM rem mag and it messed with my crono, and thats why I have "NA" in that spot.
