Rather than wasting a whole bunch ofbullets on the very first shot of your brand new brassgetting out dents etc... what other methods do you use to "fire form" your brand new brass before you actually start working on load development?

small charge of unique, fill case with cornmeal, plug with a piece of paper towl, keep muzzle pointed downhill and fire away, if you have a brake take it off, watch the barrel heat. I've made hundreds of cases for wildcats in this manner.

Although I'd prefer not to I have made up brass for my .260 Remington using .243. In order to get the correct headspace and provide for excellent fireforming loads I use this process. Run the new.243 brass thru a 7-08 size die justo get the neck expanded, run that brass into my .260 size die to get that small false shoulder, slight crush fit in my guns chamber. Load at a known near max level and go hunting. These have proven as accurate as standard fired brass handloads.
If you have been reloading for more than a few years you should have some bullets that you just don't like for one reason or another. These would get the nod for fire forming duties, providing they are the right diameter.
I have used wax to plug and shoot .22 rim fire shells which I pulled the bullets from, but I've never tried it with centerfire before. I guess it could work but I can't say for sure.
let me clarify
in my 6.5 gibbs, I use 11 gr of unique, charge the case, put finger over the neck and tap it on a bench once, then fill to the top of the neck with cornmeal, put finger over the neck and tap it once or twice. now take a stip of paper towel about 1.5" wide and twist it up, pinch about 1"-1.5" off and stick it in the case and press it in tight with a small punch.
this creates enough pressure to move the shoulder foreward, change it to 40 degrees, and just leaves the edges of the shoulders slightly rounded.
The 7mm allen gets the same treatment only with 20 gr of unique. just be sure and resize to a slight crush fit.
NOW, I have zero experience at this but I have read of guys using a caseful of bullseye, NO PLUG, NO FILLER!!! and point the rifle up and fire. you go through cases like I do and you'll try anything!!!!!!

RR, I thinkI like your method better than filling the case with completely with bullseye. That's a whole lot of wasted powder.

so ya give it a try?
just keep muzzle pointed slightly down, if you raise it up pull the bolt and run a brush through to clean the burnt meal out of your chamber, or it will dimple your brass.

I had to experiment a bit. Your the one who told me how to do it about 4 years or more ago. I started out with 5 gr or unique, and moved up. I was using paper towels only and that caused some issues. I tried wax, and that sucked. I wanted something little more size than corn meal.
I actually reached a point where I ruined a case by it bulging for some reason toward the rim. So it takes some experiementation.
well cream of wheat works better, fills easier but it seems to be more abrasive, no proof of that but its my gut feeling. I know it can't be harder than steel, but if its hot enough it would seem to me to erode the throat to some extent.

Expanding the "new brass" thead
That's a whole lot of wasted powder.
