hey just an update on the vihtiv. N-320 use.
it is working great and with supcan also. . The stuff is a fast burner and some respect needs to be kept as it is pretty hot on the burn-chart. I was pretty leery of using it when it was recommended too me @ 1st, as I have enough years under my belt handloading to 'Know' the stuff is ' Fast '.
But I Been load working and shooting as normal & usual with my bolt 30-221 and all is good. it's great powder.
Also 1 Big plus+ as even though you use less on the load for subsonic Vel. it fills the case capacity better than like my normal powder I use, A#9 . with it's shape & size.
It has to be giving a much faster and complete burn using way less barrel length than other powders I use but still gives great results down the range from 50 to 200 yrd.
.
Adding: this. It is fast Powder and I saw fast results in Vel. Gain with small bump-ups past the 5.5 grn mark. Also saw some ' little'-fluff/burn just barely sneaking up and over the case mouth on the expansion and contraction of the fired Brass on inspection.
I Definitely Would NOT want to ever throw a Double-Load on accident or get to carried-away with the powder & I think it is a general rule that & ' not advised' to use this fast a burn-rate for 30-221/Whisper. But So Far, I LIKE IT.
.
also edit to add:
Not intended for AR semi and gas cycle is obviously a NoGo. But I think that the Bolt guys will be way happy for sure.
