Load test, 6" gong, .204 Ruger at 500 yards

I'm new to reloading, but I have worked up to a load I am reasonably happy with and with basic equipment, I think it is something I will continue with.
This morning I thought I would test 3 rounds at 500 yards to see how good or bad the current load is.
I was pleasantly surprised. First 2 were hits on the 15cm (6") gong the third went just over the top and a fourth again was a good hit. (I couldn't resist firing a fourth :-) )
On examination of the gong, the 3 hits formed a 3" group but the mpi was slightly high which might have accounted for the miss which went just over the top.
Based purely on the 3 hits, that formed a .6 MOA group, I was more than happy considering as I am using a bog standard CZ527 rifle with no modifications or gucci optics.
With practice and more experience at reloading, I am sure I will be able to get even tighter groups.
Enjoy
