Care? I happen to like shooters choice, and their oil.

Feeding? I've owned as many as 4 .22LRs at once, and guess what? EACH had their own favorites - it depends on how they are chambered, and rifles, plus on the individual firearm

One loved Rem Standard Velocity (TRY and find that), one (my 10-22) loved Remington High Velocity - my Savage target rifle loved certain lots of Eley Tenex (Please do NOT pass out when you look at the price tag on THAT ammo - $18/box - of 50, NOT for a brick)

So, with that, we are talking rifles that liked everything from inexpensive to 'you pay what for a box of .22 ammo?' - BTW, the gun that loved the Rem Standard didn't like the Tenex, and the 10-22 put it in the 'it's OK' category - I did have to TRY
