Re: Fireforming Pressures

A conventional load for the base cartridge will do the job fine, no fast powders or cornmeal, etc, is needed.

Re: Fireforming Pressures

Anneal your cases, charge cases to upper end of unimproved case/bullet combination, make sure that bullet is slightly into the rifling to insure case head location against bolt head and fire for effect. You should find that they shoot fine and accurate, you can then work up improved loads afterwards. Those FF loads can be used for breaking in, fun or any other use . I shot paper for a more than a few years and saw NO increase
in groups when using FF loads.

Re: Fireforming Pressures

One thing I want to make crystal clear in case it hasn't been discussed yet.

DO NOT, seat a bullet on top of a case full of cornmeal. You will blow the rifle up in your face. Paper only on top of cornmeal.

Yep, if you want to scrub the heck out of your rifle after using the pistol powder and cornmeal method go right ahead, but NO BULLETS ON TOP of it.

I actually prefer if I HAVE to use cornmeal(or farina) to charge the casings at the range and shoot into the air (when no one is there) and not bother with a paper plug.

I prefer a false shoulder, cheap bullets, and a mid-range load from the former caliber.

It has enough force to crack or break the metal baffles. (Please don't ask how I came about this little gem of truth).
I did see a photo of a brake that had been left on when fireforming with tissue paper as a wad.
It was not a pretty sight.

What is the use of fireing a charge of powder into the air or a wad of cornflower and paper either if you want to make a bang use a air filled paper bag.
Use a proper loaded cartridge on paper or on game and have fun doing it.
If nothing else the practice has got to help your grouping or game bashing.

???

The pistol powder with the cornmeal on top blows the casing out just fine. I don't like fireforming that way as it makes the rifle filthy and I'd rather shoot the dang thing anyway.
