Great Article: I truly appreciate the info. I have a number of .303's and go & no go gauges. I find that brass life is extended greatly if I only neck resize. But it is hard to do since I like shooting them all so I usually end up full length resizing. Had a number of case head separations in all my
.303's but it is no big deal. Most of the time I am only aware of it when I eject the case and then scope my target.
Thanks
Bill
