Vihtavuori powders in 300 RUM

[jmden]

Petander, Thank you for bringing this to my attention. I had printed out VV's on-line reloading information last fall and that is the one that had the same data for 30-378 Wby and the 300 Lapua Mag. VV now has new (1/2004) reloading information. My mistake. Sorry guys.

Petander,

Are VV N100 powders temp insensitive as the Hodgdon extreme powders are supposed to be? I thought that they were and now I am reading some information that suggests they are not. Does anyone know?

Thank you,

Jon Denham

For the life of me I can't remember where I read it, but I read that it was the 500 series that wat temp insensitive like Hodgdon.

Jon,

I´ll do some freezer tests to find out about it.

I also posted the question in a brand new finnish sniper board, we will have answers sooner or later.
