not a WT, but I did whack a mature mule deer at 438 yards with my 243 load 3 weeks ago. the 95 NBT is impressive. also killed a cow elk at 535ish a few years back. I've killed a few WT with this as well, but not sure on the yardage, all under 200 yards and they just dropped there. hope this helps.
Beware of any old man in a profession where one usually dies young.
