Load development continues....
The initial load that produced .25moa accuracy, (142SMK, H4831SC, Fed210M) was 'only' going 2730fps and had a terrible ES (30+). I was looking to achieve 2800 with the SMK and to reduce the ES significantly. So today I got out and tried several charge weights and primers. One of them really stood out....
Powder: 43.5 grains H4350
Primer: CCI BR2
Velocity: 2930fps with an ES of 2!
Just slightly larger than .25moa at 200 yards!
Yes, that's a three shot group, not two.
For now, this will be my go-to load for targets and varmints. I'm going to continue to work to find a load that will run closer to 2800 in the interest of preserving barrel life.
Also, working on development of a hunting load with the 140VLD.
Here's two groups at about .5moa at 200 yards.
Powder: RL17 42.5 and 44grains
Velocities: 2930 (ES = 22) and 3015 (ES = 15)
Development for this load will continue as I would like to improve accuracy a bit more.
