VaughnT - I wouldn't mind testing that load at all. The 45 grain weight of the bullet should cause it to 'scoot along' quite nicely. What is the barrel length of your AR-15? While I don't have access to a 1-in-7 twist barrel, I do have access to 1-in-9 in the common barrel lengths.

The tests are normally shot at ~ 4 feet distance from the block if no chronograph is used (which is the more fun way to do it) and ~ 8 feet if the chrono does get used. While I can accomodate any distance from the block, up to 500 yards, I usually fire the shots from a short distance from the block so that the bullet is less likely to fly out of one of the sides.

Thank you.
Tom
