bought some old .303 ammo...any good?

Oh, I figured they'd all be corrosive, at least all the old milsurps. And probably the berdan primered sporting rounds too.

I was mainly interested in finding out if this is "collectable" ammo that shouldn't be fired, and if the slotted charging clips had any collector value. And the age of the milsurp ammo kinda concerned me too, as to whether it's safe to shoot or not.

Also would like to know if I paid too much for all this, or if $155 was OK. I've never bought or even fired any .303, don't know how hard it is to find. I'm thinking I paid a little too much, but at least I can take Lil' Bubba out shootin' now. And all this ammo should be OK at the local indoor 100yd. rifle range, it's not steel, won't attract a magnet.
