The case/jackets mostly weigh around 10 grains, so you get about 15,000 45 gr. cores for 55 gr. bullets from 100 lbs. lead (7000 grains/lb.)! If you happen to own a RockChucker, Larry Blackmon sells swaging conversion and a steel die set for $465 or his BSS press and the 3 die set for $520. You still need core mold or wire and cutter and a derimmer, so you're looking at $625/$680. So your "break-even" if bullets are worth $10/100 to you is about 6500 bullets plus/minus and your time. In my experience, I can't buy bullets that perform better for $10/100 these days, so I'd keep that in mind. Plus the break point will change relative to the component prices over years, so I'm not sorry I made the investment.The 56 gr. I mostly crank out shoot great in a 1/9 AR in front of 25.0 gr. RE-15. And they are capital D Death on groundhogs ! I'm only on my third thousand so I'm about halfway even ! If you like spending spare time casting/reloading anyway, you'll probably like swaging. But if reloading seems a chore to you, you probably don't want to start down this path.
