I have run out of H4350 for my 22-250 shooting 77 to 80 grain loads. I have a batch of Nos. 77 CC that shoot well out of my 223, and would like to try a load workup in my 22-250 however, I can't find loading data for anything heavier than 70 gr on the Hogdon website, and my Nosler manual does not mention the powder I want to try, CFE223.

Anyone have QL and would be wiling to PM me a starting point and max point along with some ballpark velocities?

Lapua brass, BR2 primer, chamber is Match, barrel is 28 inch 8 twist, varmint.

Many thanks for any help.
