What rounds for a Mossberg's Tactical .22LR

[ME1099]

I just picked up a new Mossberg's Tactical .22LR Semi-Auto Rimfire Rifle.

Any recommendations on which rounds work better? (less failure to fire, failure to eject, etc) Looking for the least expensive and where to purchase, nothing fancy.

Any recommended procedures for breaking in a new rifle, and/or do's or don'ts?

Thank you for your time.

High velocity 22s and lube the gun and shoot , it lube the gun and shoot it.

Your rifle has no unusual ammunition requirements, however CCI Mark AR or Mini-Mag are probably your best bet for reliable function.

Clear rifle, clean thoroughly, observe safety rules, and shoot. Rifle break-in is a non-issue for all but the most rarefied ranks of precision rifle competitors.

My 715T eats anything I feed it, even Thunderbolts, very reliable.

I have one. Not picky at all.
Anything. I mean, anything.
I've yet to clean it as I don't want to bother with the screws, so many screws.

I put a big ol scope on it just for a photo joke, looked at it, left it on and the stupid thing will shoot a fly off a Twinkie at 50 yards.
From 10 feet away, it could be anything.
