Here is Big News for hand-loaders now using Hodgdon H4350 and Alliant Reloder 16. Vihtavuori just announced N555, an advanced new powder in the same relative burn range as H4350/RL16. Along with having a suitable burn rate for popular accuracy cartridges such as 6.5 Creedmoor and .284 Winchester, Vihtavuori’s new N555 is formulated for “clean burning characteristics and insensitivity in extreme weather conditions”. Complementing its temp stability, N555 includes an anti-fouling agent to keep barrels cleaner. In addition, Vihtavuori claims that N555’s “unmatched lot-to-lot consistency also eliminates costly range time re-developing your favorite loads”.

When can you try new N555? Vihtavuori says American retailers should have N555 in May of 2020.
