In comparing .270 to .280, though, there's not enough difference in bore diameter to make powder choice a significant factor.
Oh NO! now you’ve gone and done it ! !
Man, where U been ? Don’t you know the 280 is far superior to the 270 ?
Now you’ll be vanquished from the ‘fire’. Sorry.
Some won’t admit the CLOSENESS of those 2 cartridges.
I’ve long said, if you have a 270 you have a 280 and Vice Versa.
Now we both gotta duck !!
