Hi Coyboy, Jimm,
My advice would be to hand load from the start for your 243 Ackley, this way you can get quality brass and may be even surprise yourselves with some outstanding fireforming accuracy
I do not have any experience with this cartridge yet, but have fireformed many 220 russians into 6mm PPC. I seated the bullets hard into the rifling to stop the case moving forward in the chamber when struck by the firing pin. this allows the brass to flow forward to fill the chamber, rather then backwards, which is what happens when the case is driven forward by the firing pin untill the shoulder contacts the chamber. In severe cases weakening of the case head can occur.(the same as excessive headspace)
Try Mike Js 6mmAckley reloading page at: www.angelfire.com/sd/6mmackley
for a good discription of cream of wheat fireforming, its economical but i would still prefer loaded round fireforming.There also some beautiful rifle pictures and many good tips.
My smith has 6 month waiting list, so my rifle wont be going into his shop untill August. [img]/ubbthreads/images/graemlins/frown.gif[/img] [img]/ubbthreads/images/graemlins/frown.gif[/img]
