Thread: Whats your fire forming process?

Yes, it really depends on what results you wish to achieve as to which way you go fire forming, doing an Ackley improved case requires a bit more attention than just a simple neck down.

If you are doing 308 cases down to 260 rem you may find the case neck has become thicker. Sometimes to the point that you cannot chamber loaded rounds. You will need to outside neck trim for them to fit if this happens.

I had to do this with 200 LC brass that i formed down to 260. Didnt fire form them, but that happened in load developement

.243 260, 7mm 08 and 308 all have the same shoulder I believe. Unless you are changing to AI or Imp.

Ive got a 30 gibbs in mkv weatherby
Also have a p14 for forming brass
To form brass for that is a process
Size the kneck on 3006 to 338
Run through gibbs die so it just fits into
Chamber,
Put some shotgun powder and cream of wheat into the case,
Plug with some wax from a candle
Pull the trigger and wallah

If you already have a load for the combination of powder a projectile just load up check your sights and go hunting or go to the range
and use them for practise,
If starting fresh just do your load development it won't make stuff all difference
