2 winters ago my son was short 243 ammo (I'll not get into it - ex-FIL) on the day of season.
That said - I hit up 4 different places looking for 243 ammo - not a box to be found till the last place. Mom an Pop in a town of about 400 people. Sitting there on the shelf next to 6.5 Creed and 375 H&H Ammo.
243 may be more available but what is available might not be exactly what you want. To a lot of people it's still a varmint gun and that even extends to a few store managers.
