I have a similar delima.
I built a 30 nosler and received it 4 weeks prior to a cow elk hunt. I banged my head against the wall for 3 weeks trying go get the new fed TLR 200 to shoot. I worked extensively and couldn't eliminate fliers. This is from a known good Smith with all top shelf build components and optics.
I loaded some 215 bergers knowing I could make them shoot with little to no load development. As expected I loaded 3 groups of 3 at -.030 off and those 3 different charge weights averaged a heavy .5 at 200. Good enough, I loaded 20 of the best group and left town the next day very confident to 300 yards which I knew was more than needed for a Texas cow elk hunt. I killed the cow at 180 and a pure shoulder shot dropped her like a rock. Interior was mush, 4 broken ribs on the outbound but I couldn't find the bullet and no exit. Again it DUMPED her!
This weekend I killed a 150ish pound white tail at 265 yards with a rock solid quartering to shot. That deer ran about 50 yards with of course no blood trail in some thick and nasty brush. I found the base and core exactly where expected in between the last two ribs in the muscle, not quite making it to the skin. Additionally, the outbound shoulder was destroyed into 3 pieces and swollen to twice it's size due to internal hemroraging. I go through all this to say it's spectacularly accurate with very high bc and nasty terminal performance but had it been 30 minutes later I would have been blindly looking in the dark for that deer.
The 215 berger recovered weighed 77 grains pictured below. It's disappointing as imo is about the perfect bullet for the 300 wm or 30 nosler.
I also had similar results shooting a doe last year at 375 from a 65 creed with a 143eld-x. It exploded on entry with a rib cage hole you could squeeze a fist into. She was dead on the spot but not good for a pure rib hit at around 2200 fps.
Having said all that, I'm planning to load the 200 nos accubond as it won't destroy deer and is extremely reliable on elk which is the goal.
