How did I get an extra 150fps? 300Wby
This may be a stupid question, but on the surface it's perplexing for a simpleton like me.
Here's the data, an ideas what may be causing this?
300 Weatherby Accumark, same gun, same brass/primers, same powder load, same OAL:
168 gr Berger Classic Hunter (BC .496) = 3125fps
168 gr Nosler BT (BC .490) = 3278fps
I have a theory but tell me what you think.
