[QUOTE="rammac, post: 2043940, member: 27761"] There is a big difference between using lubricant on a case that is filled with a reduced load for fireforming and lubricating a case that is loaded with a full load. The reason a lubed case will give a good indication of the condition of the bolt face is because the case head is being pushed in to the bolt with far more pressure. Read my post more carefully, I said that it's safer and has less potential for damaging the rifle, that's a fact. You can look at the bolt face and see if there are finish problems and you can actually measure dimensions to see if it is out of spec, you don't need to stress the bolt/lugs/receiver to find those issues. Simply reducing the shoulder bump IS safer and less of a risk, that's an undeniable fact. And since there is an easy way to test the theory why not do it the easier and safer way? Your assuming that the increased bolt pressure of a reduced load is comparable to the increased bolt pressure of a full load, that's not even reasonable logic. I agree that rifle wont explode (assuming that rifle is in good condition) the first time you use a lubricated case but it certainly does stress everything much more than the designer's specifications (using a full power load, not a light load). Like all metal, hard impacts create stresses and those stresses accumulate over time. Eventually those stresses will fracture the metal. When a rifle experiences stresses that are above their design parameters it simply accelerates the time to failure. When that failure occurs I can't guess but it will be sooner than when it would have happened if you never overstressed the metal. I just don't recommend doing things that hasten the failure of firearms. [/QUOTE]
