Vihtavuori n130 & n135 temperature sensitivity

[Matt L]

I've searched the forums, but can't find a real answer. This would be used in a 223 shooting 50gr to 55gr varmint bullets and 204 shooting 32gr to 40gr varmint bullets as well. Temperature range is from 35 f to 70 f spring time shooting ground squirrels in Nv.. 5000 to 6000 elevation.

Based on QuickLoad app data for that temperature range:

.223 . . .
N130 is ~ 1.286 fps per degree
N135 is ~ 1.829 fps per degree

.204 . . .
N130 is ~ 1.714 fps per degree
N135 is ~ 2.286 fps per degree
