I use the .243 Win with 115 DTAC for HP Silhouette. At Atglen, PA, a load of 33 gns. of Varget, 2660 fps, seems to work pretty well on rams. I think there is a tendency to try to shoot these bullets too fast, resulting in bullet "blowups", targets left standing, and burned out barrels. Remember, there are 30 targets to hit before you need to worry about losing 1 or 2 rams. A CPT load of 30 Varget, 2470 fps, will help a barrel last forever. I think the light recoil will do more for improving your score than anything. Save the .260's and 7-08's for the Nationals. Us old guys with lots of arthritis and too many hot loads under the belt really appreciate the 115 DTAC. GabbyJs
