I've owned a .243 for a little over a year now. So far I tried 2 powders, RL19 and IMR4350. IMR4350 is now my first choice. It will not produce the velocity as high as RL19 but it sure shoots more accurately than RL19 and the speed is extremely consistent.
In fact I'm looking at leaving the RL powders and going back to IMR4350.
