I have a new Cooper Varminter ordered in 243, for my trip out west, to shoot PD's. I have a feeling I'm not going to have much time to work up a load for this gun. I have already bought 1000 Rem. cases, and 1000 of the Sierra 70 grain BlitsKings. Does anyone have a load that works in their Cooper, that they might be wiiling to share. I know it might not be accurate in my gun, but it'll give me a place to start. Gun is due to arrive about 2 to 3 weeks before I leave. This will be my secondary rifle.
