I heard H110 and Lil Gun will do it. Didn’t know 2400 can too. But it might be a barrel QC issue? Not the end of the world to buy a new barrel tube if the accuracy suffers.Ouch.
There are a few powders out there that'll do this. More prominent on the blued steel frame, flame cutting on the top strap.
Can't remember which ones they were,Trail boss? Lil Gun? H110?
