Hi
I worked up a load for my 6.5CM rifle
Confirmed the powder charge @ 41.3grs H4350 @CBTO= 2.119 which is 20thou off the lands from the initial measurement.
I ran the seating depth test from 2.121 with 3 thou increase in seating depth down to 2.0520
the combination shoots great as you see I have 3shots in one hole at CBTO 2.076
I have a few amazing nodes in the 0.1s but the ES sucks,
I will use this gun for shooting paper up to 1000 and steel up to 1600yards!
-I am looking for the 2 best consecutive groups, what if they don't have the best ES?
-should I go with those 2 with a little bigger group but lower ES or just go with the smallest groups even they have higher ES?
Rifle:
Defiance Ruckus
Bartlein 28" 1:7.5 M24
EC Next Gen Tuner brake set at 0
Load:
Lapua SRP
CCI 450
Berger 144 LRHT
41.3grs H4350
elevation at the time of shooting was about 700ft and temp 50-46F
