carlsen, interesting about 7mm 08. Sounds like your specific range has a lot of enthusiasts maybe? Its almost unheard of where I am, in fact I cant remember the last time I have seen one.

OP, I asked the local gunstores here what the biggest movers were( apart from 22 and 12ga)

It went 223, 308, 30-30, 243, 303. Thats just my region though. We have the worlds largest volumes of pigs, hence 30-30 still being popular as its the fastest repeat firepower available for hitting groups.

303 not so popular for hunting anymore, but ammo sales particularly onset of covid showed how many people still have them( maybe buried in the backyard or hidden under the bed lol).
