4451 loads vs H4350 Loads, how do they compare?

[XTR]

How do the charge weights compare to H4350 in the same loading?

Just looking at what I can fit in a "reference" case it looks like it's a bit more bulky. (slightly more volume for less weight)

Yes...my findings in 6.5 Creedmoor cases. I could not get enough volume with at least 5% or more compression of the charge to get within 30fps of my 'low node' H4350 load with 141 Cauterucio's at 0.012" off lands using Lapua small primer cases (Palma converts). I abandoned it for that case. It also had more carbon fouling as evident on patches.

In a 6mm Creedmoor pushing a 95gr Sierra TMK 2grs more powder than H4350 still was less than H4350. I abandoned it and decided to eat the awful high price for a LB H4350 .
