These work awsome for a .45colt, and might feed in a .45 auto, but I have never tried. Nice light bullets make for a light recoiling practice or cowboy action load. Round nose, flat point, sized at .452" and weighing 150 grains. $75 per 1000, I have 4000 available. I live in the Gorge, but can deliver to the Portland or Bend area if you are not in a hurry. I will ship but buyer pays. 5o3-7o3-2874 or email direct austensclassics at yahoo.com , but no spaces and @ instead of "at" The PM system seems to be unreliable lately so please call (NO texting) or email me Thanks and have a great day!
