H4350 or H4831SC for lowest SD and ES ?

[zipollini]

Haven't been able to find any H4350 locally for a while for my 6XC loading so I had to switch to the H4831SC. Normally use 39.5g of H4350 or 45.2g of the H4831SC to reach 3000MV. My SD with the H4831SC is around 4-5 and ES around 10-12.

Just curious - Do people find that the H4350 produces a lower SD and ES than the H4831SC ?

As a side note powder valley has 1# containers of h4350 in stock last I looked. Great people to deal with.

Low ES is not just the powder. It is the combination of cartridge, bullet, powder and primer. And that's given that you have done everyting else right and stick with one lot of all components.
