I have some commercial cast bullets (.476, 355 gr. GC) alloy unknown, at 22 BHN that I would like to get down to the 12-15 BHN range. My plan is to remove the lube and heat them in the oven to 400°, hold 30 minutes and then turn the oven off and let them come to room temperature in the oven.
What do you folks think, will this accomplish the goal? Any input welcome.
