And here are my validation shots for my previously developed load in 300 Win Mag:

Load Data:
Caliber 300 Win Mag,
Case:Nosler Custom
Primer: Federal 215M
Powder: 72 grain of N560
Bullet: Lapua Naturalis 170 grain
V0 ~ 2850 f/s

The above load produces sub-MOA accuracy both in Blaser R8 and Sauer 202 rifles. The picture below shows the Blaser R8 target. I fired 5 shots then removed the scope (Zeiss Varipoint 3-12X56) and replaced it with a low-power scope that I wanted to zero (Zeiss Varipoint 1.1-4X24) . After I zeroed in the 1.1-4X scope, I mounted the original scope back and fired another 5 shots. All 10 shots clustered in a 1.5 group validating both the load and the outstanding rail-mount system I am using on this rifle laugh

The red-paper target shows the group obtained by the low-power scope after zeroing in.

Sincerely,
-Omid
