BT Sniper BTX notch die questions
I'm interested in heavy .510 projectiles at subsonic velocity. I saw that BT Sniper had posted this:

Hope I answered your question for you, feel free to ask as many questions as need be.
Good shooting and swage on!

I'm curious as to what the maximum caliber is for that setup?
I'm envisioning:
-308 or 7.5x55 brass necked up, trimmed, and annealed appropriately.
-Expand with BT Sniper made mandrel that also allows for core seat. Seat premade core
-Switch out to BTX punch. Notch jackets.
-point form as usual in point form die.
Above would work with a cartridge case jacket because you can use the shellholder in the press to hold the case/jacket.
If you were to use a commercial jacket or desired a boat tail bullet, I don't think you would be able to get the cartridge shellholder to work. I'm thinking you could have BT Sniper make a BTX punch that would fit where the core seat punch fits.
