Ok Guys need some help my source here in the City sold out of the N550, but do have the N150. My question is what's the difference between these two powders, and would the N150 work with the 150grn bullets?
I tried to tell you about this yesterday, but nobody will listen.
You wont get quite as much speed with the VVN150 as you will with the VVN550 but as a more than adequate trade-off you will get about twice the number of shots before re-barrel time, as an added bonus VVN150 is also cheaper adding to the bargain!!!

p.s. the biggest difference between these two powder's is that 150 is a single base powder and 550 is a double base, the double base has a higher flame temp and for some reason VihtaVuori's flame temp exceeds other manufacturers that also use a double formula.
