I saw H-Varget for 29$ recently. I looked at the price of my old jar of Varget and it was 21$. It tends to be more expensive than other powders I see on shelf at reloader supply store. I am experimenting with 50gr SP, 55gr Blitz King, 60gr, 63gr and 69gr Match King Sierra bullets for my 1:9 twist 20in AR. I have used 26gr Varget to drop in them all, as my load data showed less than max for all loads. I am going the single-shot route for the 69gr MatchKings. So the powder has same amount of room as the shorter bullets.
On the FC brass, not sure how to get much more Varget in there. It was at the base of the neck with 26gr with no tamping.
