IŽve been reading the forum for sometime and started to developed dies for making lead projectiles for my air rifles. Here in Mexico we are facing strict regulations on firearms so airguns are an option, I own 3 modified airforce condors in .25, .30 and .410 cal. I cast lead bullets for them but tried to experiment with swaging and got really involved. Many questions were answered here but practice makes perfect so I tried and tried. One of the main problems I faced was how to extract the swaged bullet... so I developed an automatic ejector.
No measurements are provided since its very easy to adapt to your needs, I used a 1/2" 20 thread to connect them to my dies and work perfectly, if you play with the length of the ejector rod you also get the bonus of making hollow point bullets (if you use a longer ejector rod it makes hollow point bullets).
I used a piece of scrap iron tubing, a strong spring (1/8" wire) , two end caps, a spring guide (the ejection rod is fixed with a headless screw to the guide), ejection rod, an "indicator" if a bullet jams simply tap the indicator.
I was able to buy a Lee cast classic press, and works perfectly for swaging, after the ejection problem my bullets were getting stuck in the base punch (I also use it to make rbt bullets) the solution is to make it hollow (the punch) placing an internal and smaller rod inside and using the ram stop(?) to block it (in the downward stroke) to eject the bullet, (IŽll place photos tomorrow)
Sorry for the quality of the diagram but it is easy to follow, hope it is useful for someone
