Last week I developed my first ever hand loads, both in .223. One for 69gr SMKs and one for 55gr V-max. As I was just starting out, I wanted a powder that would suit both bullets to keep things simple and keep costs down. I have a Lee manual which listed Varget as being suitable for both so thats what I went with and the results were very pleasing.
I'm now hearing that Varget is in extremely short supply so I'm looking for an alternative. My local RFD always has lots of Viht, which my Lee manual lists as suitable for the 69gr but doesn't list any Viht powders as being suitable for 55gr frangible. The thing I found odd is that it lists 3 different Viht powders in the 55gr jacketed section. Like I say, I'm only a novice but I don't understand why it makes such a massive difference whether it's frangible or not if they are both the same weight.
Does anyone use Viht with 55gr =V-max without any issues?
