Here's a few pictures and tips from some recent, random swaging.
A trick I came up with is to wet tumble finished bullets in standard air-rifle BBs in the standard case cleaning solution of dish soap/Lemishine. The BBs "shot peen" everything nice and smooth and the detergent sure makes them shiny!
These aren't tricks but here's a comparison of a sectioned 300gr .375 made from .223, 7.62x39, and .308 brass. I'm liking the .308 jacket for heavy game! It takes four dies (.458, .430, .410, then .375) and annealing after the .430 and .410 steps. The .308 jacket also takes a much smaller core.
And here's something interesting... While making the .375 from .308 brass, I was really cranking on the core seating die to ensure the cores were fully seated. I hear that sickening "POP" a home die maker hears when they've made a bad die and it cracks. Eject the seated core assembly and what the heck is this line?!?! Well, apparently, the pressure was so high and the top punch fit tight enough that the core caused the jacket to separate and force lead through the break in the jacket! Makes a swager think again about how the core might be deforming the jacket if seated with too much pressure.
And, lastly, some recovered .411dia/350gr bonded bullets. First two are from a big spruce stump used as a target backer and the last on the right is from water.
