I use N-133 for a 223 Rem. chambered Tikka. What everyone
said, fast, clean, and very consistent(reads accurate).
I use N-140 in my 22-250 Rem. chambered Howa Varminter.
Same as N-133. Fast clean, and consistent...Very consistent.
I use N-160 in my 6mm Rem. chambered custom barrel on a
Savage 16 action. What can I say. Again fast, clean, and
makes itty bitty groups...Even with Barnes Tipped Triple Shock
bullets, which can be challenging to find accurate loads for.
I load with a number of different powders, and Vihtavuori
doesn't always yield the best grouping loads, but on average
it is in the same league as Benchmark for accuracy and Varget
for speed. I usually start with a Vihtavuori powder, and if
a bullet/cartridge doesn't yield acceptable groups, I go
to Hodgdon, Alliant, IMR, or Winchester powders.
Yes it is a little more expensive, and availability is always
a concern. I just shop around for the powders I use, and
when I find it at a decent price, I stock up.
