Fire forming question

[One Shot]

How do you do it ?
Thankls

a lead bullet is safer, and a small charge of pistol powder.

It kind of depends on how much your changing, If I'm blowing out a case quite a bit I usually do 2 stages. 1. I load primer add some pistol powder (I use about 1.5 gr Red Dot) oatmeal to keep powder in back near primer. I then use wax cast in a sheet about 1/4" thick and push down into neck till neck cuts through sheet of wax. Then step out to shooting area aim in safe direction and fire cases.
This procedure normally will not bring you a crisp sharp shoulder but will form case to 99%.
You them load a medium load with lead or cull bullets and fire normally.
At this point you'll clean sharp shoulders with only trimming left.
This is only one way, there are many others, including just firing factory ammo which I often do, if your careful you won't have many failures. I value my brass highly. Of the whole shooting the only thing I can't make is the brass, pamper it but when it get's tired through it down stomp on it and dispose.

Howdy One Shot. I've read the replies you have been given, and also your other thread on 300/221. I assume your fire forming 300/221 brass. My experience with this centres around IHMSA shooting. When we fire form cases that have been expanded, we just load our standard competition load (which would only be a medium load) and then just shoot the round off. We would do this during practice, and then use the newly formed cases for competion use. We do this for 300/221 (which we call 300Whisper in Australia), 7TCU and also for 22K Hornet. Use lead cast projectiles for the cost factor. I use lead cast for comp anyway. Cheers, Yulie.
