This morning i cooked wife breakfast, trimmed a tree, hauled the branches to the dump site, sold 9 bottles of Reloder 19, and somehow managed to catch a 120g Ballistic Tip fired from the 6.5 Bench Rest Magnum. The load was 38g of Norma URP powder. The capture was done by 4 milk jugs filled with water, backed up by a phone book stack.
The previous two pictures show how the horse bucked after the bullet impacted. The next picture is about 1/10 second after impact, and shows the front jug flying toward the rifle, which i thought peculiar. This jug was shredded, and ended up 20' or so closer to the rifle than it was initially.
After half second, the second jug in nearly on the ground.
The following picture was taken about one second after impact.

A look at Kennedy's head in the Abraham Zapruder film shows the same thing!
On another note, many bullets loose their core when shot into water, the common assumption is that the water either acts as a lube or that it gets behind the core and builds pressure.
Way cool. I shot the 120BT for a few seasons on deer. Although they are accurate, I was never happy with the wound channel. Not one exited on 4 deer, and left poor blood trails, not that it was a problem due to very little tracking required. I always got the same jacket/core separation that you showed, again not a problem with a dead deer, but not good if it goes thru your meat grinder. I switched to the 129SST, and they are bad to the bone. With the ogive being much more sleeker, you can seat them out a lot further to gain case capacity. And they are extremely accurate, fly unbelievably flat, and have exited from every angle and hit I have put them thru, including 2 scapula shots on 150lb deer. Same similar constructed bullet with two different attitudes. Shot from a 260Rem T/C Encore handgun. Have fun.

Thanks for the suggestion. Myself, i fully expected the 120g Ballistic Tip to shoot right through deer. If they don't, i won't use them anymore. Years ago we used this bullet out of a custom 6.5-06 on antelope, and it sure dropped them at all ranges. For me they will get first chance on deer this fall, but if they don't exit, they are done. Around here there are a bunch of 125g partition, that may get a chance. The 130g accubond looks good too, but they might be hard to find. The SST will get a chance, if the ballistic tip fails.
The reason for the jug coming towards the shooter in this case is because it is bouncing off the "backstop" of the second jug. It is exploding and moving in the direction of least resistance. Try shooting a lone jug and see what it does. It won't come back at you.
In the military, it is common to place an explosive device in the corner of a room as opposed in the center of a room. The blast is then focused, and forced, to go in one general direction and not 360 degrees. This more than doubles the efficiency of the blast and allows a higher velocity of the sharpnel

There is very little evidence from the picture of exactly what jug #2 did. It obviously wasn't impacted with the same force as jug #1. They were impacted within a nano second of each other and jug #2 was at least partially trapped, AND being forced to stand still as the 1st jug exerted pressure towards it.
Remember those swinging ball gadgets where there are like 5 balled dangling from strings? You raise one ball and allow it to impact the other 4. What happens? The ball on the opposite end moves and the other balls all stand still. This may not be apples to apples. However, just because jug #1 moved so much backwards doesn't imply that Jug #2 should do anything. It is in a completely different position, took way less energy, and the forces against it are not apples to apples.
Was this shot taken from a grassy knoll or from up on your deck?
Mr. Rate: That's how a conspiracy works. Them boys on the Grassy Knoll they were dead within three hours, buried in the d**ned desert, unmarked graves out past Terlingua. Nick Memphis: You know this for a fact? Mr. Rate: Still got the shovel...
Continuing the reloading of the 6.5 bench rest magnum, i did some reloading, and shooting yesterday, and some shooting and clocking today. The load was 120g ballistic tip, 38.2g of Norma URP, CCI 200 primer, and the brass was RP previously fired 6 times. Four shots were clocked at 2635 fps, 2635 fps, 2640 fps, and 2635 fps. The best group shot using this URP powder is an irregular triangular shaped 3 shots at 357 yard. Furthest corners were 2" center.
Yesterday, i filmed a pretzel jug filled with water being struck by the bullet from the load. This i did, because i have no more milk jugs, wasn't patient to wait for sister to drain one of hers, and to humor the JFK historian(s). Stills from the video follow.
