Qagmire, Try H4831sc for the 190's as I feel varget is a little fast burning for that weight of bullet. You'll get better velocity with this powder and bullet combo. I'm using 48 grains of it which is not even close to listed max load. I don't feel I need to load this bullet to hot that's what magnums are for. So here's the load: Berger 190vld, I'm using once fired federal brass(doesn't really matter what you use) 48 grains of h4831sc, federal gm 210 primers. I use a vld deburring tool on the necks. I'm seating these bullets slighltly into the lands. I'm getting 5 shot groups in the .2's and .3's with a ruger vt .308.
