Depends. For my accuracy loads, out to 600 yards, I've had good luck with 8208XBR. For plinking loads, especially for my AR pistol, I use H4198. It is a fast burning powder so I get less muzzle flash with the pistol, and it is also very economical since a full charge for a 55gn bullet is only 21.0gn.What powder are you guys using?
