fireforming cases.

doest it affect accuracy much.

reason for the question is the current batch of brass im on is starting to show signs of wear and needing to be chucked in the can. bad planning on my part i guess with not having abunch of formed cases on hand, but with the hunts fast approaching i dont have the time to be forming cases with squib loads just to be turning around and loading them up again.

do i really have anything to worry about?

opinions please. experience preferred [img]/ubbthreads/images/graemlins/grin.gif[/img]

Re: fireforming cases.

First what are you fire forming? I have done plenty of fire forming, with some calibers the accuracy is real good with others marginal...what are your groups like?

Re: fireforming cases.

I never form with squib loads. If they fit tight on the shoulder somewhere accuracy should be very good. The brass is just like the bladder in a fuel tank. It is tight against the chamber walls long before any real pressure developes anyway. Now as long as the bullet in nice and straight in the bore and the seating depth is on your sweet spot there is no reason it shouldn't be just fine.

Re: fireforming cases.

I fireform all my brass before loading for accuracy. I do this because I neck size for the most part and it gives me a better case/chamber fit. If you plan on FL sizing, just run them through your die now and have at it. If the brass and other components are from the same lot as used before, accuracy should be as expected.

Of course, testing the final product is always a good idea.

An easy way to form brass is to use Cream of Wheat (COW) or cornmeal over a light charge of pistol/shotgun powder.

You don't waste a bullet nor wear your barrel excessively. Helps you get rid of all those old or mystery primers too.

Re: fireforming cases.

Why are you fire forming? Usually a fireformed load is for a wildcat or ackley improved version of the case. Just load up your normal load and go.

Re: fireforming cases.

....please expand on this technique.

i have a bunch of blue dot.
how much do i charge it with, and do i fill the remainder of the case with c.o.w? how do you keep from spilling the c.o.w out the end of the case if its not in a solid form?

thanks
