Varget and N150
Varget is my personal favorite with the 190MK. Loaded to 2600 fps it is very accurate.

190 SMK's
Thanks for the reply. I did try Varget and it worked well. I used 43.2 Varget, BR2 primer and Lapua brass. However, it appears to be somewhat a hot load in my rifle so I may have to reduce the charge a bit. I was shooting at about 25 degrees F and was getting shiny extractor rub marks. What would you suggest for Varget and N150?
Thanks again, Steve

Varget ala 2208
2600 + very acurate, but lot to lot can be sometimes inconsistent.(1 to 1.5 gr.) in 308W but to be fair I may have it stored for some time also.

I second the N550 with the 190s. I tried a few different powders, loading till I got cratering, and got better velocity with N550 than with Varget or H4350. H4350 was not far behind the N550 load and gave lower ES/higher velocity than Varget

SteveB. My load is 49 gn of H4350 (actualy AR2209 which is identical powder but with a Hodgdon label). I have used up to 49.5gn with no problems, no sticky cases, but 49 was slightly more accurate.
You might ask how I fit this amount of powder into the case. You will have to use a fairly long narrow drop tube under a funnel and tap the powder pan on the funnel as you trickle it through, taking about 6 seconds or so to trickle it. This way will settle the powder lower in the case, try it if you havent already. I also went to Winchester cases which have slightly more volume than the Lapuas. My throat is a standard Palma chamber and BULLETS ARE MOLLIED.
Bullets were about 0.010" into the lands
49gn gave 2650 fps
49.5gns gave close to 2700fps in a 27" barrel SLIGHT primer cratering.
If I say that this load prefers PMC russian primers, people will poopoo it so I wont mention that.
