Re: 168 gn SMK 300WM Powder
I am using H-4350 with 190SMKs and there is still some airspace - it would be a very good pick fore the 168's.
Max for H-4350 would be around 74gr at 3300 fps.
77gr of H-4831 would also get you 3300 fps.
The "H" powders burn very clean and have good temperature stability.
