Do the SST's typically like a lot of jump?
Was building loads for 7mm-08 with 139 SST. Anything close to 2.8" shot poorly. Best groups were .070 off at 2.75"
Next rifle getting the SST treatment is a 260 Rem with match chamber. Likes everything around 2.805-2.815, including 130 Accubond, 130 ELD-M and some others. Measurement to lands with the 130 SST gives COAL of 2.818. First groups at typical lengths were poor which got me to thinking about what the bullet likes. Interested to hear what others have learned about the SST.
