my reflection on this has ever been: what's the cost of new brass VS the value of my free time, i just throw them in the recycling bin, doesn't worth much to me.
I have and have used the Dillon Super Swager & the RCBS and think they both suck. Neither of those two beat a chucked Wilson chamfer tool in a cordless drill.
I use the RCBS swager for 7.62 and 5.56 military brass works great for me.
Got a picture and/or a part #?
