Yes it is a Corbin set up. The first Swaging set up I brought Was in the late 80s. It was, Mighty Mite press, a four die set to make open and lead tip bullets in .224. A derim die to make jackets from fired .22 rimfire cases, also one to make them into .243 Jackets, 1000 j4 jackets In .224 all for the sum of $769.00. I don’t think that would get you a press now. Dave Corbin used to make what he called Pro Swage dies to fit standard reloading presses which made lead bullets. Might be worth a look. The die I use is a corbin one. The minimal bearing surface on small caliber lead bullets, I found made them very hard to get to shoot accurately. I got much better results with semi wad cutter type What I would call pistol bullets. I got those shooting really well. That was all sub 12 ft/lb break barrel though. New pcp air rifles a capable of so much more. Phone Dave Corbin and have a word with him, he’s a good guy to talk to and is very knowledgeable in all things bullet.
