Tested a few hollow points in 18" of wet newspaper using #7.
165gr rangert I pulled from 40cal bullet expanded to .830
140gr barnes tac-xp expanded to .780
165gr GS to .700 at the pedals(bullet just starting to lose jacket)
165gr GD went the distance but stopped at the bottom. .640
155gr xtp which was loaded a little warmer was .720 and held together in good shape.

Is that the barnes and the golden saber in the second pic? Those golden saber petals look like they could cut some meat up.

barnes and ranger t. And yes they would cut some meat. In the past when I loaded then faster, it shed its jacket, but still looked like it would do alot of damage. The GS was the next deepest penetrater behind the GD.

How deep did the 155XTP penetrate? How hot did you load it and with which powder?

Thanks

Tex I tried to keep it at around 1300fps. Accurate arms data for max of #7 is 12.7gr for over 1300fps. I cut it back to 12.5gr using wolf standard LP primers. It penetrated almost as much as the 165gr. ranger did and expanded well. They'll shed their jackets too at too high of speed. Here's a pic of the mushroomed 165gr GS with 12gr of #7. I cut back a little more on the ranger though. You take these bullets any faster and most will shed jackets(the barnes and gold dot will fold pedals behind them). This is just a soaked newspaper test though. I just did it for fun, not to help me decide anything. I did want to see what the 140gr barnes bullet will do at 10mm velocity.(11.8gr #7) I tried to go a little over 12gr but I think it started compressing the long*** hollowpoint. 11.8gr is pretty accurate too and pretty expensive.

Thanks for the info. I measured
Some 155 XTP's on Friday 1335ft/sec avg std dev of 11.3 10 rounds using 10.2 Power Pistol CCI300 primers 1.255 OAL and these were accurate. With no pressure issues. There is room to go up a little so I reduced OAL to 1.252 and used CCI350 LPM and a tad more crimp. I am looking for 1350 ft/sec
Was unsure of expansion. With your info I will now be using them for carry.

I loaded some(155gr) with powerpistol at 10gr. with Fed GM155M primers but havent shot them yet. From what I've been reading a magnum primer doesnt help powerpistol for some reason,velocity wise:dunno:. But the accuracy and expansion of the #7 load did surprise me. The last time I tested XTP's (with powerpistol),I must have driven them too fast and they shed jackets but still penetrated alright. I believe they were 180gr though. Not that this is a bad thing.:cool:

Nice pictures. Thanks for posting them! It is always cool to see the business end of our efferts. Those Black Talons, errrr, Rangers always look mean in their full exansion - especially in 45 caliber.

Thought I'd jump in with some additional data points on the 155 gr XTP. Backing off a few tenths from Hornady max, Blue Dot pushed that projectile to 1400 fps with a CCI 300 primer. I don't have it in front of me, but the SD was low. Accuracy was fine too through a G20.

That was a cold weather test, so it would probably pick up few more fps at standard temps. I have not tested that particular projectile in any sort of media, but I suspect that jacket separation would be an issue at that velocity.
