Comparing SST & Deep Curl?
This morning what i wished to do was shoot from sticks. Two rifle came along. The Knight Disc Elite 45 shooting 200g SST, 120g BH, Harvester sabot, W209 primer. The Omega Dream Season shooting 300g Deep Curl, 100g BH, crush rib sabot, W209 primer. Dream season has iron sights, the Elite has optic sights.
First thing was to set a powder jug filled with water on a stump, but whilst walking out to 120 yard, the jug was blown/slipped off the stump. Rather than walk back to the jug, just went ahead and shot at the bottom, which was facing. Shooting off the sticks with the dream season, the jug was just so barely 'winged', which allowed the water to drain, and left the jug a 'dry' target.
The ruint jug was partially filled with rocks, so it would sit on the stump, and a move was made to 220 yard. Shooting off the bipod at 220 yard iron sights turned out to be futile. However, using the bipod, and standing, the scoped rifle hit, and knocked the 'dry' jug over.
Returning to 120 yard, the jug was once again set on the stump with some rocks in it for ballast. After the Omega was loaded, the jug fell/blew off the stump again, and couldn't be seen because it fell behind the stump. A walk back to the jug was necessary, and the jug was carefully set on the stump. Upon returning out to 120 yard, the bipod was utilized, and whilst standing, the 'dry' jug was plunked with a deep curl.
The hole at the upper right was made by the 200g SST, from 220 yard, and the lower hole was made by the 300g Deep Curl from 120 yard.
First photo below shows the exit side, and the entrance hole viewed back through the exit hole. These holes were punched by the 200g SST.
The following photo shows both the exit, and the entrance holes punched by the 300g Deep Curl, taken from the exit side.
Note the SST is traveling faster when impacting the jug, from 220 yard, than the Deep Curl, when impacting the jug from 120 yard.

Right now, i am feeling kinda stoopid. The reason i started this thread is because i was surprised how the Deep Curl showed signs of expansion, whereas the SST obviously did not. Josmund' question woke me up. What i now believe happened, is the Deep Curl hit one of them rock i put in the bottom of the jug for ballast, and the fragments made the ragged larger exit hole. Why i didn't see this initially, i just don't know.
This morning when i reexamined the jug, there appears to be a fine dust inside there, and also there are smallish dents in the plastic. So, it appears the bullet hit a rock, after it entered the jug. One more test is necessary, but right now it appear, this thread is a waste of time and energy.

This Thread is about nothing! The dummy that initiated the thread thought that the Deep Curl bullet expanded better than the SST bullet. The same jug was shot today using the same Deep Curl bullet, and the same distance, and the same powder load. Notice the 3 Deep Curl exit holes.
Evidently the reason for the large exit hole yesterday was because the bullet hit the rocks that were placed in the bottom of the jug by the dummy, so the wind didn't blow the jug down. Why the dummy didn't make a connection between the ballast and the large exit hole, is an unanswered mystery.
