Here is my first ladder test I've ever done. I'm looking for input and if I'm on the right track. Here is the info.
Phoenix Custom Rifles
PTG firing pin/spring
H-S Precision Sendero takeoff stock
28" Kreiger Barrel
Badger Thruster Brake
PTG .25 lug
Timney 510 Triger @2lbs.
Nightforce 40moa rail
Vortex Razor HD 5-20x50 EBR-2B 25moa turret
I loaded the 300 Rum with brand new remington brass, fed 215m primers, 230 berger match hybrid target, brass oal @ 2.40, coal 3.918, and retumbo.
Shot @ 300 yards prone with rest and rear bag. Zero wind, 50 degrees, 2100ft elevation. Dialed 2 moa up from my 200 yard zero with an estimated muzzle velo of 2900. Shot two sighter shots and then proceeded.
3.) 85.0-bad primer didn't ignite
9.) 88.0 MAX
10.) 88.5 MAX+
11.) 89.0 MAX+
12.) 89.5 MAX+
From looking at the pic I believe shots 7, 8, 9 are the node. They Measured .869 ctc at 300 yards.
What do you guys see? I am I reading this correctly? I may go back and load shots 7,8,9,10, 11, 12, and maybe 13,14,15 just to see if I can see my max pressure. What do you think? Also I want to move my coal to 3.900 so I am not in the lands. After the primer failed on shot 3 I lifted my bolt and pulled back but only the case and powder came! Bullet was stuck and powder everywhere. Luckily I always have my range box with me and quickly cleaned up the mess! This is getting fun if I am able to improve the 7,89, group! I also have 3 pounds of H-1000 and 8lbs. of Retumbo. Im thinking of doing a new ladder test with H-1000, would this be a waste of time and money? Please let me know if I'm on the right track, Thanks!
