Fire forming

[mconwa951]

I recently purchased new brass for my 300wsm which I have never done I've always just bought factory ammo and shot it then reloaded the cases. Do I need to fire form these before starting load development or should I just go ahead and start loading for accuracy right away?

If you bought the proper casings ( the proper caliber...etc) no need to fireform......just load up and have at it
