VihtaVouri Reloading Data tool

I have it on my fone and computer for nearly 10 years. Some data changed over the years but 2grs in 308win. Make sure you save a file or a download cause updates will lose info. On other forums some say their data is accurate within a degree (+/- fps).

It's a good guide for what powders they recommend for calibers. For quite a while, I've been using Alliant in nearly all the guns I reload for but have been experimenting with these powders more as Alliant powder becomes less available. Even these powders don't seem readily available where I'm at and it seems, if I buy a pound and like what I see, it might take a while before seeing it again. The frustration of reloading for me lately.

I'm currently only using N560 full time in my 300 prc, it lists a max load at 72.7 grains. I'm loaded at 75.1, not seeing pressure signs and GRT program shows it to be right at 65k psi. Another interesting this I noticed, which is a topic for another thread. The load I shoot was 2957 fps average over 2 bottles of powder. I picked up 2 new bottles and the same load with the powders from a different lot are 50 fps slower on average after 20 rounds. I never seen that much variance between lots of powders before.
 
I have not used it yet because it did not have my bullet in the database for 45/70 with the nosler ballistic silvertip but could use the sierra hollow point as a starting point. I can use it for the Hornady 350 grain round nose though.
