Greetings:

I have a question and would love to get the communities opinion.
I am hosting another indoor game where the fps rules state 350fps with 6mm .20 bb's.

Here lies the problem. One player has a 8mm MARUSHIN MOSSBERG M500 shotgun that can't be cronied properly due to it's 8mm .43 bb's. I dont know if this would be safe for indoor. I cannot find suffienent information regarding the joules this gun can produce compared to a 6mm .20 350fps airsoft gun.

Any with this?
