How many times?

does anyone know how many times a person can safely reload the .300 win-mag?...i do a full case resize after every fireing (heard this wasnt the best thing to do with this calliber) but brass is fairly inexpensive..the next time i reload it will be the 4th time the brass has been fully resized...my loads i've been using are a 2.5 grains less than max...should i start thinking about getting new brass?

I generally used to load belted magnums 4-5 times when full length sizing. I got really spooked when I found out about case separation just above the belt.
The way to extend that of course is to neck size only and that way the case will headspace on the shoulder not the belt. A collet type die helps even more. Also, loading down a bit never hurts. You still need to take a long thin caliper of some kind and see if you are getting a weak band there. Even just lightly running a dental pick up the side would tell you. It should remain smooth up the side. A weak case will give a slight indentation. Anyways that's just something to look for. I've always found that to be more of the problem than thin necks and splits there. -Good luck
I limit my hunting loads to no more than 5 reloads after which, if everything still seems fine, I give the brass a rest and use it for lower powered target and range work. With rifles like my early Mannlicher that, despite it's incredible workmanship, has a design that handles gas leaks not well at all, I limit my shooting, in the woods OR at the range, to 3 to 5 reloads and I check for separation religiously. One face full of hot gas is enough for me.
Good luck.
