I have a couple questions regarding my brand new Starline 45-70 cases. I will be loading them with 405gr .459 diam. hard cast bullets to moderate loads of approx. 1400-1500fps. They will be shot out of my H&R Buff. Class. w/32" barrel. 1) How many times approx. can I expect to be able to reload using this same brass...3,4,5 or more? 2) Will it help to prolong their life by annealing the case mouths after x-amount of reloading them? I will be using a seperate mouth expander die but I of course will not be expanding the mouths any more than I have to. I know working the case mouths like this can cause some stressing over time....but how much time? I have some experience loading 45LC with some pretty heavy loads and I do flare the case mouths.....I haven't noticed any cracking or splitting at the case mouth so far after reloading them 4 or 5 times. My objective is to get as much life out of these 45-70 cases as humanly possible, they ARE expensive and I'm not made of money! Part of my background is technical (electro-mechanical) if that helps with your response. Please advise, thank-you, David.
