Daryl, .303 and I are expressing sarcasm. Meaning the opposite of what is said.

I'm sure when the .300 Winchester Magnum was the "Creedmoor" of the day, it was said the .30-06 was obsolete and dead. Yet today I would guess more .30-06s would be sold than.300 Win Mags?

I expect one-day the same for the other current 100% unmentionable manbun cartridge ...
