So here is the story:
I have acquired 200 pieces of fine looking once fired 6x47sm, and I've been having a dickens of a time forming it to fireform in my 6x47L
What I've come to find is that the base is .001 larger than the 6x47L. What can I do to form this last bit? Could I use a small base .308 die to form the case just above the casehead, or will that not work?
I've already shaved off .005 of the forster 6x47L full length die in hopes of achieving "chamberable" brass...but that is not the real issue...
Open to all reasonable suggestions. I don't want to give up on this one.

Give up on this one, Save yourself the frustration.
" Trash The Brass "
I've had 3 lots or more than 1000 pcs. of the junk, and once it's been fired in a over-sized chamber it will all ways be hard to size down and you will have terrible extraction problems. The stuff is a nightmare to work with.
Buy the 47 Lapua brass and don't look back.
actually I like rem .22-250 brass for my .22 and 6mm X 47L chamberings. my favorite brass to reform to 47L is the Remington .22-250 " nickel plated stuff " . It works great.
E-mail me your address and I'll send you a few fired cases.

I have Lapua brass as well, so I'm not completely devastated.
However, I am curious...what did you do to resize the once fired SM case?

I searched your posts and saw that you used a .243AI FL to size the base back....as fortune would have it, I have a Redding .243AI die set.
I also noticed that you are in So Cal. I'm an Ohio transplant in Livermore CA. Sounds like you have some good places to play down your way.

Well, my .243AI Redding Body die removed .5 thousands off the fired case, but I still have .5 thousands to go before it will chamber.
Still open for suggestions.
Like I said earlier...I am not going to let this one go...it is just brass...it should be able to be reformed.

I gave up on the stuff a few years back. But as I recall I used my .308 small based die to get the base to fit my chambers.
My findings were once the base has been fired in a large chamber you may size it down to what you need to get it in your gun.
But, The base of the brass is hard unlike the neck and shoulder.
after firing it it does not have any spring back and it will be stuck in your chamber. I would like to suggest that you only load a few to try before making a big batch.
Be sure to take a large dead blow hammer with you ! you will need to extract your fired cases.
Please advise how it turns out. I my learn something that I missed in my attempts

Did you anneal the neck and shoulder prior to fireforming?

You can probaly sell the Swiss Match brass for as much money as brand new 47 Lapua brass.If you have enough pieces someone will get a reameer made to fit the brass.
