After spending WAAYYY too much time shooting :D I have finally settled on a new 69gr Sierra MK load for my AR-15 Service Rifle. It took a lot of frustration to reach this point, but I made it. Here are a few things I learned:
1) If developing a 200/300 yard load, 100 yard groups are irrelevent! What looks good at 200 isn't always pretty at 100 and vice versa. Several people have informed me that this is particularly common with boat-tailed bullets.
2) I tried to like, I WANTED to like, but I don't really like Hodgdon's Varget in .223 loading. I can get good groups with it, don't get me wrong, but I can't seem to get enough powder into the case to get the velocity I want without majorly compressing the charge. Oh well, I'll just burn up what I have left in something else (my .260 perhaps?). (Edit: Upon closer inspection, I think the Varget is a good bet. Retract this statement, but I will not remove it.)
3) I really like WW748 ball powder. This may put me at a disadvantage in Highpower competition, but I doubt it. The confidence I have with loading this powder in MY rifle should count for more than anything else I can do.
4) If it is going to be a long, drawn out process with lots of rounds launched down range before I find what I want, I'd rather have to do it with a smaller caliber rifle. :)
And lastly,
5) Patience is the key to finding a good combination. Luck and voodoo may be helpful, but will never replace a calm, methodical head.
Thanks for listening to me rant. If anybody has any thoughts, please share.

Edited to add that I was on a search for 2700-2750 fps (+/-) with acceptable accuracy.
