I would also expect a sabotted 260gr WW lead bullet moving faster to react in a different manner in different media. Considering his method for checking hardness with a center punch, that might be a variable too. Not all WW lead is the same hardness. Difference in the metaplat <sp> size is another variable. Corey's 260s looked like they did pretty good and that wide metaplat should really transfer some energy.

you can push saboted boolits harder then conical. so comparing .452 boolit using an sabot to an full bore, water test to an wet newspaper test. you'll should think you would get two different results.

Corey, thanks for confirming... Bet you did not know you were using simple physics to come to that conclusion. I reamember I hated Physics in school and an I made a point of telling the teachers, what would you ever use it for in real life???? I hate it when a teacher might be right...

I am not quite sure what is being discussed here. I believe we are saying that using different media to test bullets, will end in different results. I agree; that is obvious. Shooting bullets into phone books, is much harder on any bullet, than shooting them into jugs filled with water.
I hope it is not being inferred that we cannot compare different types of bullets. This final jug test using a conicical instead of a sabot, resulted in what i believe is a valid comparison between bullets. The conical was given what we thought was the same amount of energy as the sabot bullets, when it was sent on it's way, and this resulted in quite a bullet performance. What i didn't realize was the conical did not weigh 460g, and thus actually had less energy than all the other 300g bullets tested.
What happened in these test is, all the 300g bullet, and the concical bullet carried about the same energy into the water jugs, and this allows for a direct comparison of these bullet. This test comparing sabot bullet, and conical bullet was instructive to me, and i believe valid.
The one bullet that got a raw deal here was the 200g SST. It was tested at the same speed as the 300g bullets, and thus carried much less energy into the jugs. I obviously didn't put enough thought into testing this 200g bullet. However, it still managed to convince me to give it a try this next season, on prairie deer.

Ron, your comparisons are fine. At least as good as you can make them. The last part of this thread is more about the 260gr bullets into sand compared to your 460gr test into a different media and other variables.
Most of us, including yourself understands this difference in expansion and how the bullets performed. Your videos help even more when broke down frame by frame. They help give an idea of how the energy is being transferred.
