other than the sig cross and their speer firearms rated for/up to 80k, has anyone reloaded for tis cartridge in a firearm up to 65k yet? just bought some hybrid cases, dies and some 27cal projectiles for an upcoming ar barrel (plans on not going over the 65k mark). been using ql to runs numbers although i don't have all of the needed info to get safe results (case capacity, exact projectile(s) being used and known velocity). i haven't checked if xxlreloading or loaddata yet for possible numbers.
