[QUOTE="Fiftydriver, post: 175463, member: 10"] Catshooter, Using oil definately helped, especially with the smaller cases but when we tested this die on my 7mm AM and 277 AM, both based on the Lapua case, nothing worked well. Water only resulted in a slightly rounded shoulder. Oil produced a bit more shoulder puch but not much, still would need to load with a fireforming load before going to full pressure loadings. We tested light oil as well as heavy oil. Did not make any differnece that I could see. If you could hook one of these dies up to a closed curcuit hydralic system they may work very well but for the heavy cases, they simply do not work. Plus, the fact you have to wash the cases with thinner to get the oil out is a pain in the rear. Drying cases is enough if a pain but oil inside the cases is not my idea of a good thing. Just my personal opinion. For me and my wildcats, I simply formed up a fireforming jig that screws into an old Rem 721 receiver. Works great. I have stubs for anything up to my 338 AM so all I need to do is change forming barrels. Much easier for me anyway. In my testing, oil did not make enough difference to change my mind on the function of these dies on lapua class wildcats. Kirby Allen(50) [/QUOTE]
