Re: Help with BC calculation
You posted that you were using 58.5 grs of H4831sc in an '06 case, is that correct? The reason I ask is because that's nearly 9 grs. over the listed max in the Hornady manual for the 140 sst. They list their vel. at 2800fps for 49.4 grs of H4831, I would think 58.5 grs would be clipping along at more than 2975 fps.
P.S. I'm curious enough that I ordered 2 boxes to try in my 6.5-284.
Ignorance can be treated with education, sadly there is no cure for stupidity.
