I recently got a 1000 of the plated Extreme bullets. I loaded some up using the data I use for Hornady XTP bullets. I noticed something very strange here: velocity was about 100 FPS less than the jacketed Hornady 158g XTP in my 4.2" SP101 and SIGNIFICANTLY slower in my Ruger LCR 357, about 150 FPS! I don't really know what's going on here with the velocity, but it was very consistent across about 10 shots each. I left my chronograph notebook at the cabin, so I don't have the exact numbers in front of me. I will update this post when I get back from the cabin next week. I ADDED CORRECT CHRONO READINGS
This is my load and chrono data (velocities for the Xtreme bullets are in bold):
158g Hornady XTP
158g Xtreme 357 HP
17g H110 (Max by Lyman, work your way up)
Magnum Primer
Heavy roll crimp
Ruger SP101 4.2": 1270 FPS / 1156 FPS
Ruger LCR 1.875": 1124 FPS / 970 FPS
-----
158g Hornady XTP
158g Xtreme 357 HP
8.4g Power Pistol
Standard Primer
Light Taper Crimp
Ruger SP101 4.2": 1198 FPS / 1070 FPS (These do about 1500 FPS in a rifle and shoot/load very nice)
Ruger LCR 1.875": 1100 FPS / 934 FPS
Now for the expansion tests:
I shot these into water only. I did it old school with a big pail. I used a contractors trash can and filled it with 30" of water. I only used the H110 loads from above. The XTP bullets were going 1270 FPS and the Xtreme Hollowpoints were going 1120 FPS. The XTP's performed beautifully, the Xtremes did something weird.
Average Retained Weight:
Xtreme HP: 135g (118g, 131g, 156g)
Hornady XTP: 137g (132g, 138g, 141g)
Average Expansion:
Xtreme HP: .41" (.41" + .38" + .44")
Hornady XTP: .53" (.54" + .51" + .55")
Conclusion: just like what Xtreme says, these bullets are not expanding bullets. They either lose their noses or fail to expand at all. I really have to get to the bottom of their velocity loss. I actually really like the Power Pistol Load I posed above for a mid-level plinker. Leading was very minimal, even with heavy crimps and very top-end magnum loads, this was a big bonus in my book.
I never tested the XTPs before and many people claim they tend to not open up. In my opinion, these bullets performed PERFECTLY and I will never shoot another jacketed bullet from my revolvers! They are clean, accurate, and now I now they expand really well.
I will buy more of these Xtreme bullets as soon as mine are gone. They are clean and accurate and I was hoping for expansion but definitely not expecting it. I would love to hear some velocity numbers from others that have loaded these vs. jacketed bullets.

I almost never have powder marks from the loads I shoot! I have a feeling this has something to do with the low velocities I was seeing. Any input? These are 158g Xtreme HPs with 17g H110, mag primers, and heavy roll crimp:
They are very accurate (at 10 yards) from my rifle:
And anyone can shoot revolvers better than me, but this is a good group for me (4.2" SP101):
10 shots over the power pistol:
Picture of the family:
After shooting revolvers all day, I tried out my new LCP...
You don't hold revolvers and autos the same way . I never do this while standing and shooting an auto, but since 99% of the shooting I do on a sandbag is with a revolver I hold autos like a revolver when shooting off a bag... I've done this before with a TCP... I knew it was going to happen too: notice the buffed edges on the rear of my LCP slide
