they sell them cheap because of economies of scale. making 1 wdiget is expensive. making 80 million widgets is much cheaper. there is nothing wrong with them. I wouldn't use them for competition, but for cans and squirrels they are great. they go bang when you pull the trigger (unless you are shooting remington golden bullets, then you have a 90% chance of bang) and run within about 75 fps of each other according my chronograph. I THINK i recall it being about 1050 fps +/- 50.
the federals are the best. my guns (ruger mk2 and ruger 10/22) eat them all day long without hitch. winchester super X jammed occasionally in the mark 2, the old remington thunderbolts ran fine, and the remington golden bullets are a plague. 1 out of 10 will either be a dud that might fire if you try it again, or be oversized and jam. If you can find them, buy federal. if not, buy what you can find, but expect a certain amount of frustration and know how to clear a jam safely.
lead bullets are fine. even the bullets that are copper plated are lead underneath, and the plating is not a jacket like on a 9mm. it's much much thinner.
head the general wisdom here, you will do more damage to your barrel by cleaning aggressively than you will be shooting it dirty.
