At my last range session, I got exactly the same accuracy with 300 grain Hornady XTP hollow points as I did with Sierra 300 grain jacketed soft points (which have a flat lead nose).
The load was 100 grains Triple 7 with a Harvester crush rib sabot.
A fifty-yard five shot group of the Hornadys measured 1 5/8" center to center and chronographed at 1747 fps (average for 5 shots).
A fifty-yard five shot group of the Sierras also measured 1 5/8" and chronographed at 1737 fps.
A fifty-yard five shot group of 250 grain Speer Gold Dot hollow points measured 2 1/8" and chronographed at 1850 fps.
