‘What calibre might be best per accessibility to ammo and performance?”

Great question. These are the best calibers for the typical shooter to go with.
22LR, 9mm, 357/38, 5.56/223, 308. They are plentiful and will always be the most available

Thank you! Great!... So, on the AR that you built, was that 22lr?

I’ll definitely need to find cleaning classes, soon.

Except when they aren’t. In the last round of panic buying, the local BiMart ran out of those. The shelves were packed with .40 S&W and 6.5 Creedmoor, though, for a while. Pretty sure there was s 2 box limit, per customer, per caliber.

Don’t count on an adequate supply chain.
