I should have an opportunity this weekend to not only shoot another match but to also finally get a hard zero on my PCC. Details of which are a little foggy in my mind at the moment, but IIRC it's a 10.5 in barrel, free floated, with a Holosun 512C on top.
if the use-case for this thing is steel challenge, USPSA, etc. then at what distance is the convention to zero?
