That's not true at all.
Example- gas blow backs can use 6.02 just fine....
HPA style rifles are not very effective with 6.02, anyone who tells you they are knows nothing about HPA's.
Widebore barrels are far more effective in HPA compared to TBB.

He Said 6,20 not 6,02 so it is a widebore he is talking about
