Take the rifle the bullets are coming out of into context.
This isn't a precision bolt gun shooting match hand loaded ammo.
Showing a fast 10 round group with irons off a bag prone unsupported at 100 meters is a great reflection of what to expect accuracy wise. Because its exactly how 95% of the people who buy this gun are going to shoot it.
I have seen people shooting supermatch ammo through this gun and posting pics of 1" 5 round groups after waiting 2 minutes between shots etc
To me those accurracy results are completely irelevant as almost Noone is ever going to shoot this cheap ass, bare bones blaster in this fashion.
It's the cheapest materials on the market and as soon as it gets hot, it opens up fast. I can attest to that personally.
Would be like buying a pgw coyote and then running crates of corrosive steel cased ammo through it as fast as you can shooting from the hip and posting groups. You want to see what a rifle does when it's applied in the actual method it was designed and intended to be used.
