Interesting. I'm shooting the 85gr Sierra hollowpoints at ~2900 but they drop off very quickly past 250m. The 90gr TNT's haven't given me or shooting buddy particularly good accuracy. These could be well worth a shot. What length barrel are you shooting them out of?
Edit: I use a 20" Howa so have run the numbers in QuickLOAD. It's apparently not great at predicting Grendel loads, but assuming 2.260" OAL, it's predicting 1% compression and 2695fps with 34gr of CFE223, pressure quite low at 43.5K psi.
I think quick load is way off with that prediction mate
If you look online 65grendel.com mainly Obviously depending on powder change and oal etc
Most guys are getting 2800-2950 with cfe223 and 95vmax
