    Thanks for looking...

    If anyone in the SE Mich area would have a chrono that they’d be willing to let me borrow (or meet you), so that I can collect some ballistic data on a couple of rebarreled rifles, that’d be appreciated. No urgency, since I’m often too busy to get to the range as frequently as I’d like.

    Thanks,
    Brendan

    Easy to do without a chrony - Zero at 100. Then shoot at 300. Measure the drop at 300. Use a ballistic app with the bullet BC and adjust velocity until the velocity matches the drop at 300.

    Watch this guy...
