Fire-forming with cereal question???
I need to fire-form some .17 carbine brass to get some cases exactly formed to my rifle chamber. Using the cereal method, how much pistol powder (Unique or Bullseye) should I use? I think case capacity of the cartridge is about 17 grains of H2o. Just trying to make sure I don't use too much powder.
Thanks, Jordan |

Just forget doing that and load what you plan
on shooting. They'll be perfectly formed then. Saves on powder and primers too. Main thing is be mighty careful loading these tiny cases. I blew a gun up once with just a .1gr increase. After firing ten shots in the same case a .1gr less that was just fine. Good luck and have fun.

When I was doing some testing to evaluate impact to COAL on a cartridges development I was using 8.0gr - 9.0gr of Bullseye for blowing out .223 cases to 6x45AI. Obviously, the charge would be less for the smaller 30 carbine case.
As George indicated...if you can avoid the cornmeal step then by all means go straight to loading and shooting. As long as your resized/formed cases are reasonably close to your chamber then there shouldn't be any concern about case separation. I was surprised by how accurate these fire forming rounds performed. |

George has it right, forget cereal.

Should I use Fruit Loops or Cheerios?
Load a few light and work up to a load that forms the case 90% or better and load them all up and go kill stuff while fireforming. |

cow forming
I have use 7 grs of bullseye with cream of wheat and a dap of crisco to hold it in place while forming, but as others have said, it's not my first choice anymore. if you are going to do it, work your way up until you are satisfied you have a fully formed case.

Maybe a guy or two of you can expound on this whole cereal deal about how it's actually done ( in detail please), since I could not find it on youtube.
I tried this MANY years ago and I never succeeded. The cereal never held firmly in place to cause enough pressure to expand the case, and it simply blew out of the barrel. To succeed, I did ram a series of small pieces of paper hard into the case (without cereal) but it required so much time and fussing that I rejected that idea. |

http://www.saubier.com/forum/showthread.php?t=35289 It made sense in my application because I was trying to accomplish 2 things: (1) convert standard 223 Rem to a Ackley Improved profile and (2) expand case neck to 6mm. If I were just trying to make 223AI then the load and fire technique would have been perfect. |
