If you size a lot each time you will not get 40 cycles IMHO.
Maybe fitted brass and tight (or tighter) necked chamber?
As an example, my 300 WM sized with a Redding neck bushing die (I now use a Lee Collett and anneal) and bumping the shoulder 1 thou every 4th re-load had me splitting necks (like a gas vent in the neck) between 7 and 10 reloads.
That said the fired brass was around .340 as I recall and the WW brass was quite thin. The bushing was a .330 or .331, so I was sizing quite a bit.
I've heard of 20 plus reloads in tight chambers.
