I am going to start with Broz's load as starting point.
Yes, my first 30-378 was a factory accumark with a 10 twist. The next one had a 30" HS preciaion barrel and it also was a 10 twist. Many people stoot the 210 Bergers from an 11 but I prefer the 10.
That load has worked well in many rifles and many of them accumarks. A little bedding of the front lug area and a barrel free float will help your rifle too. The load is plenty soft and velocity from a 26" barrel will be about 3050. Like I said, not a sreamer and there is room to hop it up, but my accuracy,ES and case life was so good I was not about to go for more velocity I didn't really need. Believe me that load has taken lots of game. Including the Elk below that is holding up my accumark..
