this is the entire 7.62x25 swaging operation from jacket blank to finished bullet. https://www.youtube.com/watch?v=KkeIq31P4iM
this is how i do it, except this time i used an arbor press to trim and swage the bullet as anyone can go down to Harbor Freight Tools and pick up a small arbor press. this usually goes a lot faster. having to hold the camera, using only one hand, and using the arbor press slows me down a bit. i usually use my pneumatic press that is many times faster, but i used the arbor press as it is easier to get hold of for most people...
im using aluminum flashing, the same stuff they make gutters out of that i get for scrap prices. aint got **** in the bullets as far as price.. maybe $0.01 per bullet, if even that much. the lead is just soft lead like plumbers use that i cast into cores and trimmed to length. these end up being a shade under 85gr. im loading them to around 1,500fps using reformed .223 brass for my CZ-52..
but these are the ones that mushroom so well that i posted about in another thread. these transfer all 450ft/lbs of energy in around 5 inches of wet newspaper. they totally shuck the jacket and the core turns totally inside out after turning into a flat disk about 1/3 of the way in b4 folding back in on itself. i wouldn't want to get hit by them. that much energy transferred in that short a span would be like getting hit in the chest with a sledge hammer. i did manage to just about totally eliminate the possibility of over penetration. should make great defense rounds for my pocket artillery..
