Re: .308 WIN Spindrift?
Yep, it exists in a 308 and all other projectiles out of a rifled bore.
I just don't think it matters "that much" or I'm just not advanced enough in my shooting.
If I could ever master the "wind" thing then I'd probably think about spin drift a bit more.
Another thought, right or wrong, if one "sights in" on a far distant target and regularly hits it under no wind conditions, wouldn't spin drift automatically factored, though unknowingly, in to the process.? Just a tho't.
