The Berger MEF 30gr. hollow point is fast and accurate with little deformation in my experience. You might try some out on some freezer burned meat or wet phone books and see how they do for you. I run them in reduced loads, so I don't know if they would perform different in your AR or not. I saw nice wound channeling in a thawed out turkey roast at a distance of 50yds with no signs of blow out. I later shot a gray fox with a passthrough and had no damage, but I did have a tough tracking job as I had a less than ideal hit. Entry and exit were about .22 caliber sized with no tearing.
