I've had much better accuracy with Federal blue box & fusion ammo across several rifles, than any other brand. As has been mentioned, many times it was so good I wouldn't bother with reloading for that particular rifle. If you stick with the 95 grain & up offerings, I doubt a .243 could stress 'em enough to have bullet problems.
On a whim, I once ran some Remington & Winchester factory rounds across a concentricity gauge, and found the results to track exactly with the accuracy I'd seen from them. I didn't have any Federal ammo on hand at the time, but I'd bet a Happy Hour beer it would be fairly concentric.
