    Any idea how your velocity changes? I know when I'm at the end of a 20 round string my barrel can get up to about 160 and my FPS goes up 20fps or so...

    On the other hand, steel expands roughly a thou every 100 degrees F.

    I've never ran it across a chrono in a match, guess I need to try it.

    For me 15 to 20 shots at most then let it cool...I clean after every shooting outing before rifle goes away..

    We chatted about barrel temps on another forum a while back.

    Some of the fastest kool down tools are, a bucket of water with a rag. It's not my favorite tool since things get pretty wet,,, but it seems to work.

    A battery powered Coalman air mattress pump works good .

    Leave the bolt open, put the discharge spout into the action as the out side air flow will knock the temps in a few minutes.

    Quick, simple ,easy and frugal, about $10 Usd or @20 Cnd funds.

    Those little pumps take up nill for room and weigh in at just over a lb with batteries installed.
