Pulling bullets/Oatmeal

[etisll40]

I've got some factory ammo in 7 stw and I want to pull the bullets and put some oatmeal in or something and fireform them. Has anyone done this? I'm thinking, I don't need all the powder in them? Maybe pour half out and then put the oatmeal in? Will that be enough? If it is, I can use the remaining powder in fireforming some other cases? Please chime in.

Thanks,
Ed

not a chance would I do that. First off you are playing with case capacities vrs load density and to top it all off you are adding unknown compounds. Let some other poor smuck blow up their gun.

By dumping out half the powder, I'm not adding anything, I'm reducing the charge? Not sure if you understand or am I missing something. How do you fireform? and what powder do you use?

In the reloading manuals, they refer to squib loads and there danger for good reason.

All powders have an oxygen content built into the formula and if you create a large space by reducing the volume of powder, it increases the burn rate and may exceed max pressures by many thousands of pounds.

I prefer to load cases with somewhere between minimum and maximum to shoot them the first time
and if they are wildcats and have to be fire formed I load medium to near max for the parent cartridge because when it fires it has more powder volume because of the chamber.

This is safe and gives me nice crisp fire formed cases. In most cases they are also accurate enough to hunt reasonable ranges with, so you save brass and utilize components at the same time.

Corn meal is for cornbread not rifles. (I realize that some people do use the corn meal method to fire form there brass) but most of the time the brass needs one more fire forming to make it fit the chamber and reach maximum powder volume.

Just my opinion

Sounds like I should just shoot the rounds for fireforming as is. Thanks for chiming in.

The only time I use a reduced charge is with live rounds. And I use a "faster" powder with a real bullet, usually Reloder 19 with a cheap Hornady Interlock or Nosler Custom Comp in a weight that I don't use for actual load development. I also run about a 75% load, not a 50% load. But this is usually for forming my wildcats and my Ackley Improved brass, where you're moving shoulder angles and case walls and lots of brass moving around in different directions, so as not to split the necks or shoulders.

However, with the slower factory powder and just forming cases for a standardized chamber (7mm STW) with correct matching cartridge brass (also 7mm STW), I agree with the above posters, and just recommend shooting the ammo as-is for fire-forming.

I understand, I'll take your advice.

Thank you

Not a problem man. That's what these forums are for. Let us know how it turns out.
