I am having a .300 RUM built on a Rem 700 long action. The rifle is being built by a gentleman of great reputation and will have a 5 contour Lilja barrel, non-fluted, 27 inches long plus a muzzle brake.
He will develop a load for the rifle which will probably consist of: Remington brass, Federal 215 magnum primer, some unknown amount of Reloader 25 (I would guess in excess of 95 grains), and a 180 grain bullet--not sure which one, but it will have a BC of .511. He full-length resizes each time.
I asked him how many loadings I could expect with hot loads from the brass and he said he limits himself to 2X loadings.
Three questions:
First: How does that assessment compare to the experiences of other experts out there. Is two loadings about the most I should expect?
Second: How can I tell by inspection or measurement of the brass--at any point in its life--whether it might have one more loading left in it? I know of course to inspect for head expansion, cracks, dents, etc. but what--beyond that could be done?
Third: If a person backed off to approximately factory loadings, what kind of brass life should one expect from magnum cartridges.
I appreciate the input--all of my past reloading many years ago was with .223, .308, .270, and .30/06 and of course I got pretty good brass life out of those cartridges.
