Thread: Reloading .223/5.56 for an AR15

Does anyone have any tips or helpful info on reloading for an AR?
Have reloaded for many other rifle calibres, .204, 22 Hornet, 7/08, 30-06, 308 etc...but have no experience loading for an auto?
I have some small base dies on my watchlist as this would be the first step...
I was using the Hornady 75g Match ammo but only have a few boxes of this left. This was a great round in my Colt, it was accurate and had enough horsepower to put down reds at sensible distances and found it deadly on pigs so ideally would like to load something similar to this so have been looking over the Sierra 69 & 77g projectiles which look like they might suit?
I have easy access to all ADI powders along with the other usual suspects but what have people had good success with?
Any opinions or info much appreciated!
