For AR-MPR, I’m chasing a .5 – .75 MOA accuracy goal. Initially, I started with 3-shot groups when I function tested the rifle, but have upgraded the challenge to “consistent 5-shot groups at .5 – .75 MOA”. In order to track my progress, I’ve taken a hint from Paul over at http://accurateshooter.com – use the free OnTarget software that you can download here. This software makes consistently measuring your groups easy!
Here’s an example 5-shot group from my last trip to the range with the AR-MPR rifle:
As you can see here, I hit .759 MOA which is just .009 MOA too large! I think that’s half the fun with this project is getting everything dialed in for consistent tight groups (including the shooter).
I’ll do additional range reports as we finish our video series on single-stage precision loading with the Redding Big Boss II here shortly.
If you like to quantify your range results, give OnTarget a try!
