7828 and 7828SC in .416

[manykids]

I'm preparing a batch of. 416 Weatherby rounds and am going to use 300 gn TSX over 119 gn of RE19. It's been nearly ten years since I ran the last batch and don't recall if I crimped the bullets, I'm thinking it isn't necessary, what is the recommendation from the members here?  My supplies of RE19 and RE22 is becoming limited but I have several pounds of 7828 and 7828SC on hand and I've heard good things about it in smaller bore calibers.  I wonder if anyone here has experience with it in their .416 rifle.

Niether powder is in the Barnes manual !  You might check with the powder maker.

7828 would be my 6th or 7th choice in the 416.

My Nosler book says that I.M.R. 7828 is the most accurate powder tested,115grain with a 400 grain bullet.
