I use IMR-4198 in my 204's with a 32 gr v-max with very good results. I've also had good luck with varget with 40 gr. v-max's. Whats your rifle got for a barrel twist? I've herd a lot of people having problems with the heavier bullets with a 1-12 twist. Also seating depth can change your accuracy as well.
