As I'm waiting for the acetone/shellac mix (slurry) to mostly dry out, I'm setting up the next batch of primers and keep doing this until I have as many primers as I'm going to use or want to store, usually 100 or more in one session.
After I have a bunch of primers that I just removed from the cutting board waiting for them to completely dry out, I take a primer and a sanding block and begin the slow and really tedious process of "brushing" off any excess powder that has stuck to the cup. Also, if there's too much on top, I'll scrape off that with the razor blade and run the sanding block over it to smooth it out.
You now have a completed primer ready to be seated in a case. But before you do that, when you have the primer in that doodad lever thingamajig, put a drop or two of just acetone onto the primer! This'll make the primer temporarily inert. When I wasn't using acetone I had a couple go off and THAT'S A BIG BIG BANG, and a bunch of smoke.
You will find that some of the primers may not seat very well or at all. That's all you! You need to make sure you've prepped the primer properly as well as the cases you will be using. However, being the stupid idiot I am, I'll smack the lever of the press pretty darn hard to get the primer to seat. That usually works.
Remember, I placed several drops of acetone on the primer so when I slam/smack the press lever, the primer cannot go off. This usually will seat the primer.
But again, sometimes ya just can't get the primer to cooperate. Fine, punch the primer out of the case and try another one. Helps if you have properly prepped the case too.
Now you know how to make your own primers. A big pain in the @#$% but if you're like me and gotsta go shoot sumthin' and can't find large rifle primers or your money tree is dead, then this is what ya do!!!
You'll probably have some FTF's or hang fires in the beginning, I did, still do once in awhile. But as you do more of these you'll get better results.
I'm sure I missed some small detail that makes or breaks all the effort involved. Sorry. Cuss me out, call me names, blame my parents, whatever makes you happy. I'm not a snowflake or a pansy, I can take it. (probably not!
)
Good luck
and happy
shooting!
