I've always ordered the Remington corelok bulk bullets in 55 grain soft points. And I use the same powder and charge that I've used since about 1977. Just a plain ole bullet at 3300fps. Its always worked, and I can load'em in my sleep.
I've never owned an AR that didn't like the load. That deer took my typical lung/heart shot and humped up, walked about 30' and gave up the ghost.
That bullet and that shot will usually exit on a whitetail, but it didn't on this bigger mulie. All the blood was out of his mouth. His lung were a mess when we gutted him out.
