forming dasher brass with just primer/powder

[distantfoe]

Anyone using a method for forming dasher brass that doesn't involve a bullet or food items.

I seem to remember a method that included creating the false shoulder, then fireforming with a primer and pistol powder. (pointing bbl into the air) Does this sound right?

I use shotgun or pistol powder.

Start with a half case, thrown from a powder measure.

WRITE THE CHARGE DOWN, or mark it on the case as shown below. Backside of case has 'clays' written on it indicating the powder used. File the cases and/or the paperwork somewhere, this is just as critical as any other load data.

This method is perfectly safe if YOU act safely.

Also very loud and will heat your barrel quickly. It's no less wear on the barrel IMO than just shooting bullets.

I take the time to run clear up to over-pressure, to where the pockets get loose. I find this point by decapping manually using a Wilson pin in a small arbor press. When the spent primer pops out with light finger pressure you've gone too far! Write this info down.

That's what I'm looking for! It's definately cheaper than slingin bullets and most likely easier on the barrel.

To fire form cases. .

I had a bunch of 6mm cases that I had to fire form to 22-244AI. I necked them to the .224 dim and then started out with 13 gr. of Bullseye and filled the rest of the case with ground walnut medium - then "packed" it in with a small piece of paper towel to keep it from falling out when inserted into the chamber. I found that the 13 gr. was a bit short and went to 15 gr., that seemed to work out the shoulder quite well. I fire formed 100 cases that way and am still using them. I found with the 13 gr. that the shoulder was still a little too round and the 15 punched it out to nearly perfect. Do this at a range, or some place that you will not be disturbing someone - it is just like firing the rifle only No Recoil, and it didn't disturb the barrel at all. I took a cleaning rod and ran that down the bore about every 20 rounds "Just to be sure" that nothing is hanging up or getting lodged in the bore . . came out clean every time. . . .
