Hi all. Just did my first (ever) ladder test and could use some help reading the bones here.
Rifle is a Remington 700 SPS tactical in 223, 1:8.75 twist (traded for a spare parts built M-4orgery).
Test is with LC 17 brass (full length resized, flash hole deburred, sorted for weight and case mouth tension), varying charges of AR Comp (22.1 to 24.1), CCI #41. All topped with Hornady 75gr BTHP.
Ogive length on the bullets varied by about ten thousandths, but as best I could all were loaded to within 5 thousandths of the lands. No crimp.
Target range was 370 yards.

To my eyes, it looks like shots 5,6, and 7 would be promising, but I’m a novice so I’d love whatever feedback I could get.
