New N555 Powder from Vihtavuori -- H4350 Burn Range

[mike06]

I have two 8lb kegs shipping today. I am hoping it will at least match my H4350 loads in my 6.5 CM.
I like to buy powder in pairs of 8lb and I haven't been able to do that with H4350 for a long time. I have wanted to find second powder to have on the shelf. Hope this works.

I am going to send you a pm of my 6.5 CM 555 loads. do you have excel?

I was wondering how that N555 turned out? Or if you’d had time to burn any?

Sons CM didnt like it as much as H4350. Perhaps we just didnt hit the sweet spot

A few days after I bought the N555, I received notification that a big back (over a year old) order of H4350 was being shipped. I still gave the 555 a try but it was pretty slow and deviations bad. On top of that I was compressing powder .8 grains below VV days. 555 was easy to sell at break even. So I'm happy.

My son tested it in his 6.5 manbun (CM) and said rifle didnt shoot as good as H-4350 and Leverevolution
