Thinking about it then, if say I got a new, I dunno, AA 410, and it was doing 11.8 from factory, I could potentially contact the old bill that I could potentially have a been sold a firearm...
Just a thought.
I see in Airgun editorials and such, reviews of certain rifles... in the specifications list on the review they often note down the power, some are indeed 11.8... logic says that they could be over.
