Well, I figured I'd post an update on what I found. I bought a box of
Nosler Ballistic Tip 165 and
Barnes Vortex 168gr TTSX. Now, just a reminder: I shoot a Rem 700 5R Milspec, so not your average hunting barrel with very different rifling than normal. I have tried Federal Sierra Match Kings and they do not shoot great.
The Nosler was the worst ammo I have ever shot. So much so that I thought it may have been me and had my buddy who is ex Marine Force Recon (Spec Ops): scout sniper trained. The result: 2 shots 8" apart one at 1:30 and the other at 7:30. This confirmed the results I was seeing and I know have half a box of the most expensive ammo that is only good for making noise.
On to the Barnes. At 100 the Barnes was more accurate in azimuth but still a lot more elevation in my groups than I would like. It performed better for my next groups at 200 and I am plenty confident in my range to be able to hit an elk out to at least 400 but the performance I am seeing would not make me want go past 500.
The funny thing is the my box of mil surplus 147gr M80 FMJ rounds are far more accurate. I am easily sub-MOA with them. I would be very interested to break out a chrono and compare the velocities to each other and the specs on the box. I know that the only way that I am going to get the performance I want is by hand loading, but I didn't expect such poor performance out of such a high end load as the Nosler.
