Good information, thank you. I’m also getting a two hole touching and one an inch away on a three shot group Consistency regardless of powder charge or powder. Gave up trying to ferret it out.
Tested CX190 loads today at -10 degrees
With WLR primers and 79.5 grs MPro 77.5 MPro and 72.5 IMR 4831
All fired with no issues and all hit center steel plate at 300 yards.
The rifle I have is a Bergara with a detachable magazine that can be loaded out to 3.55.
I do not have any R 26 and had to work up loads off of research and estimates.
It seems to me the bullet likes jump and under max loads. At 2900-2950 it is solid out to 500 at 1325 yards I saw erratic...
100 yrd for groups
Then tested at 500 and 1325 yards on steel plate.
The 2.5 group was loaded to 25 thousandths of lands
Best load was loaded to COAL of 3.500
Couple notes with the .308 190CX load in my 300WM Bergara, these are not SAAMI spec loads.
per Hornady 2000fps is the minimum impact velocity which is 600 yds @2950 fps
using SHOOTERSCALCULATORS.COM and having confirmed at 1325 yards the load has the same identical trajectory as my 190 Sierrra...
