I have experienced no problems with 10mm brass resizing (returning to spec, if you prefer) or any case bulges on brass from either the HiPoint (my 1st 10mm) or the XDM Elite. Although I, too, don't reload any real higher velocity (AKA, "Defensive-type") ammo in anything but new or once-fired Starline cases.
Just lucky, I guess?
Cheers!
P.S. I am still amazed as to just how accurate that HiPoint 10mm has proven to be. All that weight seems to negate any negative recoil effects, and it has become my test mule for both 40 S&W & 10mm reloading. Reliability has been 100%, although I did clean, lubricate & polish the feed ramp prior to firing it for the 2st time. (EDIT: Although a typo, I did shoot it once before I polished the ramp.)
