[QUOTE="Loner, post: 385024, member: 24560"] POLISHED AND LUBRICATED.... This level of friction would represent what one would expect with a polished chamber and a lightly oiled brass for Fire Forming. But one would not necessarily use a full 55,000 psi load for fire forming. Note that in the cases with Coefficient of Friction of from 0.01 to 0.10 the brass head contacts the bolt face at about 150 microseconds. The primer contacts the bolt face at about 50 microseconds. There was no firing pin or firing pin forces in the calculations. From the Varmint Al's article. [/QUOTE]
