Impressed.
The other week, we had a windless day at the club, so I popped out to the 100yard range.
With 10 shots on a card, 5 of them were in a 2cm group in the middle...
...the rest of the shots were - erm - outliers.
I notice all of your competitors were using .22 and larger calibres. There's even a few .308s! Presumably with high energies too.
How competitive would you expect a sub 16.3 joule 4.5mm rifle to be at 100m? I have JSB exacts or exact heavies in mind.
