I have some 44mag brass thats about worn out only reloaded it 28 times (going to be 29 after I finish shooting the rest). It might make it to 30.
Did you discard your lady friends when you were younger after bedding them only 7 times?
If they weren't good. YES
But seriously I trim my brass once. After that its trash can time.
Which means I can get several firings or just a few depends on manufacture?
I've thrown away Remington brass in as few as 5 firings. I personally think it was a bad lot. This same lot was .010"-.020" over SAMMI max when I bought it new.
It all depends maybe MickinColo is running his loads at MAX and thats all he can get out of brass is 7 reloading.
Which is fine anything after 3 reloading for most calibers the brass is FREE anyway.
Unless youre talking brass for my 460WBY then after 1 reloading the brass is FREE.
