[QUOTE="Chopaka81, post: 269395, member: 9217"] There are those who will get their shorts in a knot over what I am going to tell you, but this is the technique I have used for many years in developing MAX loads. I use a 1.0" micrometer capable of measuring to .0001" accurately - with an emphasis on accurately. Noting the local temperature (matching that to those encountered during hunting conditions) I increase the powder charge until I measure 0.001" case head expansion. At that point I declare that to be the MAX load for that rifle/reload combo. I then reduce the powder charge 1.0grs and use that as my hunting load. Case life is not long when you use this approach, I have had limited success in extending case life by annealing the brass. I will give you a far warning - this practice is largely opposed by many "Average Joe" reloaders. I guess what I am trying to say here is, closely monitor the case head expansion of your brass as you approach the powders charges listed in the "other reloading manuals." [/QUOTE]
