Vihtavuori Powders

[Out Back]

Could anyone tell me if

the Vihtavuori Powders Are Temperature Sensitive or not................Looking at either VV135 or VV540 for my 17 Remington

Following.....have been curious too......but I am looking at the N570

My experience with N550 has been very even from 40F-90F. Above and below that SD's climbed. This is based on a max charge, uncompressed in a 7BR with 168gn pills.

I run N570 in my 6.5 Sherman. I am in southern Manitoba so in winter I can shoot in -20 to -30 and in fall I shoot in 70-80 degrees. It has worked good for me out to just over 900 yds. I also get good velocity with it.

I also run N 570 in My Sherman so far I have not seen any changes from 0 dec C to +20 so far so good I guess I the test will be in fall when we go from +15 to -15 over night .
