Fire Forming Question

[Nevada Mike]

I have several hundred new 308 Norma Magnum brass. The factory shoulder on new brass is about .021" shorter than my fire formed rounds I have. So I need to FF ALL my brass to a consistent length for loading. Is there any way to properly FF brass without incurring several hundred rounds of barrel wear on my new Brux barrel? I have heard some people use Cream O' Wheat, but never tried it and no idea exactly how it works.

Thanks.

15 grains pistol powder, a small wad of TP, cream of wheat packed in tightly, small wad of TP, topped with a little wax or glue to hold things in.

A smear of oil or sizing wax around the shoulder to aid in filling out.

Many thanks.

I expect that HS6, Bullseye, or other fast shotgun / pistol powder will work?

For forming my wildcats I use same load as my hunting rounds. In thousands of rounds I've never had a problem and have found that they are just as accurate as the cases that have been formed and then loaded.

The cream of wheat method works great; I have used it quite a few times forming .375 H&H to 8mm Rem Mag. The only thing I can add from my experience is check your chamber area often for little cream of wheat "donuts" left behind from combustion, canned air would take care of any debris that you might find.

I suggest you just load it and go hunting. Or use some for practice and hunt with the once fired brass. I see no difference in my 338 WM loads between the two (accuracy or V).

If you are a long range shooter and shooting a tweaked custom chamber, then different story. Those guys (a couple I used to know anyway) screwed on an older barrel and did the pistol powder / cream of wheat thing.

Unfortunately .0015 to .0020" is normal for belted magnums - factory loads or new brass.
