.243 VihtaVuori Powder = Heavy Bullets

[ktm450]

H4831 is/has been out of stock forever. I am deep in the weeds on reloads for 103, 105, and 108 class bullets in a couple .243’s. VV powder is very easy to get and looks to be a good substitute on paper.

Does anyone have first-hand experience with VV160 or VV165 for heavy bullets in a .243?

Not first hand but in GRT N160 and N560 seem to be the better choices for a normal 243 (not AI) in terms of case fill and velocity.

N555 works good in my 6 creedmoor

Thanks. N555 seemed to have a burn rate close the R16 and 4350’s. N160 and N165 looked better for 100+ bullets? I appreciate the responses and will experiment with some.

Yea I’m sure they would work well. Yea I tried N555 because it was close to H4350 and R16. Both of those seem to be very popular for the 6 creed with heavier bullets.
