i want to buy some 45 colt brass for reloading in my revolvers, blackhawk and uberti. they will be lighter loads with lead bullets. all name brands Win, Rem, Hornady, starline are on backorder. the only brass i can find is Magtech. is this brass any good? the magtechs have a cannelure on the brass. i have never seen this before. i am looking for alot of reloads from the brass just for plinking with light loads.
