Cream O Wheat for fire forming

Hi Bob- Back in the days before the 300 Blackout, reasonably priced Whisper brass was hard to come by. You could go through forming either 223 or 221 Fireball cases. I tried both, and thought my loss rate was excessive. Finally, I happened on this approach. I took 100x 221 Fireball cases. I splurged for new ones. (Buying brass is something that I have to work my brain around...) I primed them with some Remington primers I'd picked up in a trade. Charge was 5 gr. of Bullseye, followed by 10 grains of Cream of Wheat (note cautions) This was topped off by a 1/4 sheet of toilet paper (ditto). Touching them off resulted in brass that looked like Yvonne Venturino had photographed it for Handloader. I didn't have to redo any of them. After that treatment, I chamfered the case mouth and all that other silly stuff.

I've done other modifications, but this is the one I could lay my hands on my notes. I'm glad I have the notes, as the cases seem to last forever-I'm doing the subsonic stuff. I avoided anything sweetened or flavored. Not sure what anything like sugar would do to a bore. Also, for similar reasons, I tried to find the option with the least sodium. (Rather than my usual groc store, I think I got Walmart's generic.) Finally, I used Scott's, which around my house is unscented, as least until used. Never know what's in that perfume.  The rifle in question is a Contender carbine, so I didn't have to worry about a gas system getting gunked up.

The best part was, although my house is too close to neighbors to allow shooting, I did the fireforming on the night of the 4th of July-I have a bulkhead in my loading area, and when there was a flurry of fireworks, I fired a few. Nice to not to have to go to the range for that chore... I assume this is for the latest Wondergun ?

Bob, googling "fire forming with cream of wheat" got a whole bunch of links, with the usual levels of good, bad, ugly and BS. Depending on the project, it might produce some data more relevant to what you're dealing with.

 Bob, I realize I"m a little cautious, but you might want to consider backing off half a grain with those pressures !  

Well I finally "shot" the Cream O Wheat . It is an easy and cheap way too fire form. I used 700X topped by toilet paper topped by a full case of C.o.W. which then I covered with T.P. I did have one case split at the new sharper shoulder,they were older Remington brass.

The procedure I used was to lube the case then partially neck size it just enough to chamber with a little effort, to keep the case from moving with the firing pin impact, and pull the trigger (this last step is a no brainer) almost fun!

Now I have to do it 50 more times but with virgin Nosler brass.

     Just for variety they do make "Cream of Rice" As for eating they both have the same consistency when made. So food for thought   when ya can't find the wheat try the rice. 

This crew is old enough to remember the "cereal shot from guns" ads, right ?

    Yes Pooh I sure do remember those. Puffed Wheat and Puff Rice.

Well today I shot 25 rounds of C.o.W. 13 grs. 700X topped by C.o.W. topped by bar soap scrapings, all worked to create perfectly formed cases.  The bar soap was easier to "seal" the case than the TP.   The only bothersome issue, I couldn't find the puffed wheat that Quaker said they got by shooting it out of a gun.

I love the incredible technical knowledge shared in this group. We have hundreds of years of combined experience dealing with all aspects of firearms and munitions. The example shared within this thread alone is nothing short of amazing. I doubt there are many sites where the complexity of combined physical and chemical requirements would be expanded to include the necessity of incorporating the correct music to reach the overall goal of such a demanding project.
