[QUOTE="Ackley Man, post: 341266, member: 16583"] Have several Ackley chambers both tight neck and SAMMI. Forget the cream of wheat crap. It serves no purpose other that to act as a case filler. Use a heavy bullet (100gr.) seated 10 grand into the lands. Use .243 Winchester (NOT ACKLEY) max load data for the bullet you select. It may not completely form shap shoulder edges the first firing but thats o.k. as flowing the brass twice always seemed to keep neck concentricity the best. The next question that you will probably be asking is "why do the fire forming loads print better that the loads after the cases have been formed?" - The answer is - don't ask. None of my contacts from Precision Shooting Magazine or any where else has ever been able to ascertain the cause and effect relationship. Good luck and have fun with your new Ackley. [/QUOTE]
