Re: Where to next??? OAL or powder type?
Berger's are a different animal, it requires a different approach. First you need to do a pressure test at the max COAL you can run in your rifle(mag box if you don't have an extended or don't want a single shot), work up slow look for signs of pressure. When you reach the book mag load stop.
Next you need to load up for a 24 round seating depth test, 4 groups of 6 rounds fired at a range of 200 meters or more. This test gets you close as you will see one of the groups will be much better than the other 3. You will need 4 different seating depths that can be found in the article I have linked in my signature line.
Now the accubonds are a little simpler, you will need to do a ladder test, I suggest 3 rounds at ever charge weight from min to max. You again will see a pattern some loads will be better than others. Seating depth will not matter much with these bullets, if you get a load close to what your looking for you can try switch primers.
Remember with all these loads we are looking for a balance, if you have a chronograph use it in your load testing. Fire all the loads over it, we are looking for the lowest ES, SD we can get!
