Should I get Golden Tiger steel or Federal AE brass 762x39?  Have not shot either so unsure of accuracy or reliability. See alot of talk on here about Golden Tiger and steel case but no talk of any type brass case. Thanks for any help

I don't think the price is even close but if it was, Federal brass any day.  Where do you see this?

Brass?  For what rifle?

I've never seen any brass cased for less than 50 cents ea. and GT is half of that. And I've not seen Federal brass close to that. Only brass I shoot is surplus Yugo, that is slightly more accurate than GT. I like Federal in other calibers as a good budget round but even if it was slightly better than GT it's not worth the cost difference. Privi is good if you have to shoot brass case and don't like corrosive Yugo but even for my best rifle Yugo shoots 95% as good as Hornady which is the best IMHO. Red Army has brass cased ammo they call comparable to Yugo M67 but I have not shot it yet.

Just an FYI, I haven't fired any yet, but the GECO .223 55gr is outstanding.

GECO 124gr .50 cents per round ,brass reloadable case.
