I load the 143 ELD-X and 147 ELD-M to jump 0.030 to the lands on my 6.5 Creedmoor measured by my Hornady OAL tool. I picked up some 129 grain SSTs and decided to load them to the Hornady manual recommended COL of 2.670 which is quite a bit of jump. On my Tikka the jump if loaded to the manual suggested COL is .252.

Have you all found the SSTs to be jump "tolerant" or do they prefer to be a certain distance from the lands?
 
I seat them to the cannelure in 30-06, they work fine there for me. The 150 SST is my A-Bolt's favorite bullet and I've never actually measured the lands for it because there's never been a need to mess with seating depth. Knocking on 3000FPS with Hodgdon Superperformance from a 22" barrel and they fit the mag so I never changed anything.
