I have had good success with 60 grain V-Max's and 23.4 grains of varget.
I also have some 69 SMK's with the same charge of varget that i haven't tried yet, the V-Max's are definitely a good bullet, just wish they made them a little heavier.
I'm using a 1/8 twist 16" RRA Varmint, so wont be able to get max velocity out of them but as long as there accurate thats all i care about
