Finally pulled the trigger on boolits for a couple of AR's. Bought an RCBS 55gr mold. My first from them. Cast them hot and fast as others have suggested. Plain ww dropped in water. Got the freechex maker and ran them thru a Lee .225 sizer to crimp the check. Used .011 thick flashing. Now all I need to do is lube and load. I'm going to use H4895 and hopefully work up a load that is accurate and will work the action.
