I thought I'd post these here as well as over on my bullet testing thread. Codyadams was generous enough to send me some 250gr SB II and 270gr SB I bullets to test in my ballistic gel. Both bullets were fired from an 18" 338/375 Ruger specialty pistol, so muzzle velocities are very similar to what you'd get from a 24" 338 Win Mag. I shot the 250gr using the same load that I use for both the 260gr Hammer Hunter and the 250gr SMK and ended up with a muzzle velocity of 2645fps. I haven't shot enough bullets in the 270gr range to have a good baseline load for that weight, so I just went with the same charge that I use with the 285gr ELDm bullets. This was obviously a low charge for the 270 and I ended up with a muzzle velocity of 2440fps, much lower than I was expecting. These are the Badland bullets compared to the others I tested. Left to right: 225 TTSX, 250 SB II, 260 Hammer Hunter, 270 SB, 285 ELDm.
Here are the still photos of the impacts.
250gr SB II impact velocity 2445fps
270gr SB I impact velocity
2245fps
The 250gr SB II penetrated 24.5", which actually surprised me, I expected more. The 270gr SB went 37", even at the low impact velocity.
Recovered bullets with the weight of the shank and all petals recovered:
Here's an interesting picture and I'm not sure what to make of it. The first 270gr bullet I fired exited the side of the block, so I fired a second one into the gel later on to get a recovered bullet. I just shot it into a block that I'd already fired a 285gr ELDm into. The glowing spot you see in the gel block here is actually the bullet tip from the Buldozer.
I'm not sure what caused this, but it's a pretty cool shot either way.
I'll have the full videos of the bullet tests from this trip posted up tomorrow night. The full video will include impacts at full and reduced speed of all 5 bullets I tested on this trip out (225gr TTSX, 250gr SB II, 260gr HH, 270gr SB, 285gr ELDm)
