This is about what I do with normal full power reloads. So I'm pretty happy. The point of impact was approx 5 inches lower than my normal loads.
My testing to do. But early signs are promising. Interested to see how AR2206H goes!
I'm not great with iron sights either, but lots of practice will improve it.
What rifle are you using?
I bought a reduced aperture for my No.4Mk1* which I think helps heaps.
In the .303 on 14gn of Trailboss I was getting around 250mm 5rd groups at 50m.
In the 91-30 it was even worse, including some tumbles at 50m.
The same bullet on 15gn of TB in the '03-A3 though groups a little better than you're seeing, with a 4rd cluster in 19.5mm at 50m.
Both of my rifles start to work with .311" jacketed bullets and .313" hardcast. The Berry's .311" plated hardcast is just undersize.
