The range I work at has enough cooling ability to pump 1200 sq ft coolant capabilities down each lane (yup you read that right)....currently with 90's and high humidity outside we are running just 1/3 of our ac units behind our shooters. It is so nice and cool inside beyond the air lock room I find myself always wishing I was in there and not out front running the counters.
For any other people who don't know how the calibers match up. I also read that 10mm has a high velocity and therefore more penetration which is why it's used for hunting vs a .45 which has a slower velocity but bigger entry/exit.
And that is why I bought a 10 mm. I plan on purchasing a longer barrel for mine so I can hunt deer with it!
