I was really happy with the accuracy of my 257Wby Accumark using the 100gr TSX. Had very tight groups and velocity was 3608fps. I tried 6 tenths of a grain more of RL-22, changed my OAL to 3.171" and my load was moving on average 3672fps and no primer or brass sign and no marks on bottom of brass. Of course I did not figure it would be over Max. since it is a publish load.
Here is the group at .512"
I have adjusted to 2 1/2" at 100yds. Well, I think I am ready to go to hunt with Jerry who I will see Sunday evening and Monday we start.
