Vihtavouri powders and the 7mm rem mag ?

[CzyHorse]

GRT puts a 160gr Partition at 3047fps over 68.7 grains of N560. 95.5% load density, 100% propellant burned when loaded to 3.340 COAL. 3298 foot/pounds of energy at the muzzle. I would start around 65 and work up.

I am quite certain that load would lock my 700 up. I stopped at 65 grains of N560 behind the 160 Partition.
Case head expansion was .0018" and the case head was marked with the ejector circle. As I stated, be
careful!! I would be starting at 63 grains of N560. Dave.

Gordon's Reloading Tool is based out of Europe and uses CIP where North America uses SAMMI.
GRT shows some pretty high Max pressures for some cartridges, eg. 357mag @ 43,511psi, 444Marlin @ 51,488psi, AFAIK a 357Mag is 36,000psi and the 444Marlin is 42,000psi.
With published load data, GRT has been fairly accurate for me in predicting muzzle velocity when I'm using a powder the program has a high confidence in/more user reports.

True - this load I mentioned is going to run right around 62kpsi. Important to start low and work up! My max is not Eagleye's max, for sure. My Tikka loves the speed.

well it looks like there is no VV N165 anywhere out there at retail.
Managed to find a source I can drive to that has a decent stock of IMR 4451 and IMR4955 so I put a few pounds of each on hold till I can make it there to pick it up.
Gonna have to work up some new loads I guess.
