Pictures on swaging a non-gascheck bullet to accept GC
My camera is not the best for close ups, but will try to show how this technique works to put a gascheck on a non-gascheck lead bullet.
You need a swaging die like C-H makes that has the rounded ogive in upper chamber of the die. This is where the bullet gets it taper roundness and flat point.
The die and bullet of your choice is requred as well as a flat or bullet head shaped punch is needed on your shellholder.
Run the bullet up into the die (backwards) so the rounded ogive area in the die will put a very slight taper on the bullets base. This requires very little pressure.
You'll know you got the die seated in the press right when the gascheck will just about slip on the taper of the bullets base. Now the press and die are set for repeated operation.
Final step is to seat the gascheck in lubesizer press, or in a swaging press.
It works extremely well, and you can do this to any hardness bullet.

PS This bullet was once a Meistercast 158 grain .38 special, swaged up to .429 diameter as .44 caliber; and a gascheck makes it now a 161 or 162 grain bullet...which is pretty lite. But you can do this to any weight size bullet.
