The cases I find to work the best new never fired are starline. Factory ammo or once fired cases I prefer Winchester or RWS. Both seem to be holding up quite well.
As to a load to use you might need to provide a little more information. Is it just for the range? Which caliber and what bullet do you plan to use. With that information maybe we can post our favorite load for you. Remember the OAL will affect the pressure of the load.
