We had a couple guys a few years back that were absolute snipers with 32 cal. squirrel guns. Lots of guys complained so we made the caliper restrictions to give guys a chance. The sniper showed up the following year with a 45 and took 3rd place. We've done it like this years, no issues.
I see said the Blind Carpenter to his Deaf Helper as he picked up his Hammer and Saw!
