Checking the measurements on some ammo I was reloading this afternoon and found that a new box of SST bullets had a difference of 10thou of an inch on the ogive to the old box. In this case it meant the new ones were 10thou further away from the lands. For those that seat close to the lands and the reverse happened this could prove dangerous so if you use them I would recommend checking for each new batch of bullets.
Mine were .264 cal (6.5x55) 140GR.
Anyone else found this or other differences?
