I would say that you found the ammo that you gun likes to eat.
I sure hope that is not the case since I can not get that ammo any more. I was shooting Federal 180 grain Nosler boat tails that I was able to buy for $18 for a box of 20 from MidwayUSA about a year ago because that loading was being discontinued by Federal and MidwayUSA was having a clearance sale on it. I still have five boxes left which will last a while since 20 rounds of .300 Weatherby Mag in one session at the range is pretty much the limit for my shoulder. I will try some other brands next time I go to the range and see if I can get equally good results.
