Expanding the "new brass" thead
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?

RE: Expanding the "new brass" thead
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.

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.

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 actually reached a point where I ruined a case by it bulging for some reason toward the rim. So it takes some experiementation.
