    First really enjoy this site and all the knowledge on it. So I would like to get some input on an idea I've been kicking around.

    I have been musing over testing some terminal performance of bullets.

    My question is can I load down to get a lower velocity so I could test at 2 or 300 yards and simulate results at 600 + yards?

    I'm shooting a Rem 700 in 7mag with a 168gr bullet with Retumbo.
    The book shows 66.0 gr as the min load at just over 2800fps.

    With my goal of testing at ~2000fps that would be 600 yard-ish. But if I could test around 200 yards that would make life alot easier.

    So to my questions-

    Any problems with shooting this slow?

    Is there a way to ballpark charge without just working down?

    Is this even a good/worthwhile idea?

    Thanks for your input.

    Talk to Barnesuser28, he is a little kid but he seems to know his stuff. Him and his dad have done exactly what you are talking about doing. He can give you some info I bet
