How to Fire Form Brass - 300 PRC Part 2 

Hi Brandon, thanks for the note and I'm glad it worked for you. I've told a few folks who are looking for 300 PRC brass to do the same thing. Not only does it get you brass in a pinch, but it gets you really good quality brass that you can use for a long time.

@@TwoMinutestoTarget so wat is your fireforming load? I went through the process and it seemed to work except the base of the case wanted to bulge out in a irregular random direction since the diameter seems to be a bit smaller than the Hornady brass dimension-don’t know if that makes a problem or not.

@@jeffreymiller5336 I ran them at under 70 gr of H1000, so quite low. 68 seemed to work well

Hi B2LEE - nice to see you here! I found that when fire forming with an initial case length of 2.59, I end up at just under 2.56, which then take a couple shots to grow back to the low 2.56s. My latest batch that I have yet to fire is starting at 2.60. Like you, I seem to be getting better results at shorter lengths, and I plan to trim them right to where you've got them at 2.565. Of note is that you lose a little length after the SECOND firing too, which is why I'm now starting at 2.6.

So I went ahead and did everything the way you explained and the only thing I’m not sure about is that after fire forming it I had a bulge at the case base out the side and it usually ended up being kind of on one side or the other not necessarily concentric around the circumference of the case - have you noticed this and have you dealt with it somehow or has it made any difference in your load work up?

I have a question I’ve completed the trimming and sizing and internal neck trim, I’m curious are you using a standard load for fire forming or are you using a reduced load?

@@jeffreymiller5336 Sorry, missed this comment. That means you're going way hot on the load. What load/powder/bullet?
