prickett - ESPC with HF red, did the dry powder with HF white on 308 boolits. Red comes out looking like post 53. White looks almost as good. I've left them cooking as long as an hour @400F & below, then WD (even checked) works fine. I don't get the dark color you did. I'm doing the HF specified cook then drop the temp 25-50F for the rest of the time. When I recook (got interrupted on a batch and they AC before I got to them) I drop down to 375F. Seems like recooking above 425-450 gets them a little sticky. I'm doing HiTek for pistol now but may use the dry HF Red for my daughter - so the SIL won't shoot all her ammo.
