155gr SOST?

[Tspeis]

It's been rumored for some time now that a 155gr 7.62x51mm SOST round is being developed for 16" guns. Anyone have info worth sharing? Thanks.

That is correct, as most folks are running the 16" 7.62x51mm rifles and the 155 gr is a better match than the 130 gr for the uses and distances currently being encountered OCONUS.

Is the bullet construction basicalky the same as the 130? I know the 130 lacks performance at distance, but seems to be a fine bullet up close. I've only had a chance to take 1 hog with it, but I was impressed. What distance is the 130 grain loading good to out of the 13" barrel, vs the 155?

I would also like to know the answers to these questions, especially the velocity thresholds for these bullets.

Doc, I assume you're talking about the SCAR primarily?

[DocGKR]

FN SCAR Mk17 is one platform, but there are other 7.62x51mm 16" barrel systems in service, like the SR25 EMC and LaRue OBR.

Considering loading some 130gr SOST rds in a 9" bbl... that said would the 155gr bullets be more benefical? Wondering the terminal ballistics of each round (both 130gr & 155gr rounds) out of the various length bbls... Any info or recommendations DocGKR?
This would be for the 300 BLK of course.

[DocGKR]

The SOST rounds are for .308 velocities and will not be optimum at the lower MV of the .300BLK.
