TBH i would prefer any review / test of a rifles shooting ability to be undertaken at least with the rifle bolted down, so you have 0 shooter in the mix.
I want to see / know what the rifle can do on its own without any shooter interference.
Like alpha precision say.
"5 shot group fit in 20 мм
with the distance of 50 meters
(for airgun barrels)"
That is quite a lot i would expect at least half of that on measly 50 M 20 mm CTC at 50 M, that’s almost where i would call scatter gun
20 mm CTC is what i expect at 100 M shooting the damn pea caliber.
