Do SST's like a lot of jump?

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.

I am sure some dedicated SST shooters will jump in to help you out... Each rifle is different though so the only way to tell what yours will like is to do some testing...

I’ve shot some 95 grain SST’s in my 243 that shot well with jump. It was quite a bit but I’m not sure exactly how much.

Not knowing if you’re shooting a BR or hunting rifle but in my mag fed 7/08 I couldn’t get 139s to shoot but the 154 SST are another story. About .035 off because of mag restrictions seems to work for them.

Just a hunting rifle. Read today that the secant ogive prefers to be either jammed or way off by .040-.120. Pretty surprised but now I know.
