Large BC Differences — Due to Barrel Differences?
I've been surprised to experience how different barrels will have varying degrees of hold off necessary for similar wind values. All else being the same, i.e. same pellet at same velocity.
OK, I really don't like reading this. Really. Don't.
Sorry.
(
Thank you to the shooter to call attention to this issue, I have nothing against you!)
What I understand from this post is that
▪ the same pellet
▪ at the same MV
▪ from different barrels
➔
suffers from a LARGE difference in its ballistic coefficient.
I acknowledge there can be
SMALL BC differences from different barrels.
But
LARGE differences?
I don't like that.
Because it would make published* BC numbers pretty useless:
Every barrel—projectile combination would have to be tested. Individually.
You guessed it: I don't like that....
*(by airgunners, manufacturers, anybody)
Please, I'd love a discussion on that. And I am open to accept what I don't like.
Please, supply some arguments or some kind of evidence (drift numbers, BC tests, etc.).
Because
the thing I like less than large BC differences is — to continue shooting in ignorance.
