Here's a few that bug me:
It's 308 Winchester, not .308 Winchester;
45 Colt, not .45 Colt or Long Colt;
30-06, not .30-06;
270 Winchester, not .270 Winchester;
45-70, not .45-70 or .45/70;
and so on.
The leading decimal point does not belong in cartridge designations.
Well, I just had to check... it seems the jury is out on this one, as every box of Weatherby ammo that I have does indeed have the caliber preceded by a decimal point. And to further confuse the situation, when I look at the stacks of boxes of UMC brass awaiting the reloading press, exactly HALF are marked 40 S&W, and the other half... you guessed it: .40 S&W. So since I've always used the decimal completely without thought, I'm in decent company if I'm wrong.
Oops... did I just use "caliber" incorrectly?
