Best Vihtavuori powders for 300 PRC.

[MichalS]

Gentelmen, I'm starting my adventure with 300 PRC and need your hepl. Most US load data are based on Hodgdon powders and I'm wondering which VV powders should I try for 185/200/225 gr class bullets? I need extreme accuracy to be competitive... If you have any pet loads that would be very helpfull.

Best regards,

Michał

Viht 165/568 , to 170/570 . Looking at the web page to get speed it’s the N 5 series that gives the best performance. 
Possibly choose what your local supplier has in stock.

N568 seems made for your calibre, N 570 will give a little extra speed. Fill a case to the start of the neck taper and weigh that and see if it fits in with the reloading data. Most of my best loads are around this point, no matter what powders I try .

I use 80g of N570 with 230g Berger OTM's.  However... I just picked this as a "mild" load while running in the barrel but during that process was i was getting good groups at 900 and 1000 yards, so have just decided to skip any load development and stuck with it.

No info for Berger bullets but this seems to be near top end of hornady 230 A- tip load according to viht web . 79.5 for hornady 230 bullet or 80.6 of n570 for 220 Berger. High 2800s fps
