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?
 
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.

Here is a pic of the Hornady reloading manual for 6 creedmoor and 105-110 bullet range.

I have no experience using VV powders. However they are listed in the Lee manual. The pictures below are from the manual.

Haven’t tested for accuracy but n565 gave me a full case and good velocity with 105 Matchburner.

Just shot a couple over the chrono to get a feel where it would be.
