Thread: Hodgdon /ADI BM8208 data

I might also add that 2 of my cartridges didn't have (one still doesn't) any manufacturer's reloading tables. Only info was network postings which you have to be very careful with.
Due to an optical chronograph giving an incorrect reading due to the sky conditions I actually went into severe overload. Found this out later on the next outing when I set the chronograph up under the shade of some pines. The optical chronograph had overstated the velocity by 100 feet per second. There was no swipe marks but the primer pockets had expanded as had the base measurement. Fortunately that was in a very strong action (Barnard) with very good gas venting should things have let go.
After that I went and treated my self to a magnetospeed.
