Hey guys,
For my most recent cartridge i have to fire form using Cream Of Wheat. I loaded 16 grains of HS-6, filled it up to about 1/8" below the neck with COW, pushed it down a bit, and capped it off with some toilet paper. My question is, will i run into problems with my muzzle brake still attached? It is a 7/8" V-port vaporizer by Nathan Dagley (straightshotgunsmithing.com). I dont want to remove it if i dont have to because i think it may cause a seam where the barrel and brake meet (it is KG coated and the brake was turned to match the barrel, i can see no seam as is right now). If someone has tried it and it worked (or didnt) please chime in and let me know.
 
First Riley, you are young enough you need to use Farina.
Second, why don't you just use mild loads and seat the bullets out??
We've done the c.o.w. and pistol powder thing with both braked and plain rifles in 7stw and it made no difference. Makes a hell of a mess in the bbl. either way.

Because i necked down 375 ruger brass to 30 cal and the chamber is a tight neck, so a loaded round wont fit. I have to fireform to get a to the 40* shoulder and less taper.
 
Sometimes I end up with those COW pieces in places they don't belong. A quick blast with an air compressor in the chamber and brake seems to take care of the problem.

Where you would expect carbon, expect breakfast.:D

Thanks for the insight, and you used paper as a cap?

Ouch, you went with a tight neck so a regular neck, stuff, and pull the trigger to form won't work well. ugh.....
I suppose the brass won't come out square enough (from necking) to thin the necks before forming will it?? If so you are stuck making breakfast.
Side note, why not use a 300 win or 300 rum and be done with it??

The case is elkaholic's design, and a great design at that. The hornady 375 ruger brass is quite thick, so even a "no turn" neck would have problems. We had a 300 rum, then had it re barreled and re-worked (by Nathan Dagley, he is in Center, ND) into this gun, plus, RUM and win mag are boring. :D
