Curious to WHO is issuing the warnings on the Vihtavuori powders?
It's just something I have seen on forms like this one. They say, "double based powders cause faster throat erosion" and then they mention VV powders.
For myself I have not noticed any problems and I use VV and various ball powders.
Still, I have seen this quite a bit, so I am asking this question. What is your experience?
