Really? I get the standard photobucket upgrade your account image. I guess as long as everybody else can see them I'm fine with it.

I can't see them on the thread but I can click on an individual pic, wade through some garbage and at least find it on photobucket. What a pain!

Yes. The pics don't show in the post itself. All I had to do was click on the photobucket icon once and the pics would come up.

Just read through the thread, holy smokes... Thank you for the testing Yorke, Steve, and everyone else. The information in this thread is enlightening and has opened up discussions on variables most wouldn't really consider. Definitely has me reconsidering twist rates for future rifles, and bullet selections as well. Testing like this at least gives us a baseline on what a bullet will perform like, although usually better when on game it certainly seems. I would love to see those new Match kings tested as well, I've heard good reports on game with the 183gr 7mm and 110gr 6mm.

Ditto on this. Thanks for the work and the detailed write-up.

The little bit of 230gr SMK testing I've seen so far is looking good fwiw. Frags like a Berger, even with the new nose design and pointing.

I have personally tested it at a muzzle velocity of 3200fps and at a range of 200 yards with an impact velocity of 2950fps. I ran it head to head with my beloved 230 Hybrid target and the 225 ELDM for comparison.
My intent was to simulate an elk shoulder with the setup being a half gallon of water followed by a 2x and then several more gallon jugs of water. It performed awesome showing Berger like fragmentation but still able to penetrate well. It performed just as well when I removed the board to simulate a softer, armpit shot. Again it fragmented impressively but penetrated deep as well.
I would not hesitate for a second to use this square on an elk shoulder or armpit at this range. The big test for me will be the slow speed impact test down in that 1500-1600fps range. I'm picking up some Trailboss today and hope to have that test complete in the next week.

Good info! Your reduced load to see "IF" it will expand at 1500' will be valid because it will expand easier at the same impact velocity, at distance, when fired from a full power load......rich

That was my thought too Rich. Not a perfect test without being fully stabilized but it should give me an idea. My SG should be around 1.42 out of this 9 twist at 1500'.
