I am having trouble understanding how this bullet could cause more damage than one that expands? Is it due to the "cutting" X on the front and the spin of the bullet? Seems like it would just "pencil" through, but due to the front, that may be why the difference?

It also looks funky in how it would fly vs a spire point. Anyone tried these for accuracy and velocity drop off at long range?

Tx, the flutes cut into the nose of the bullet create a sort of "vortex" in tissue with higher fluid content. It's quite devastating to the internal organs as several hogs dropped by my .458 SOCOM will attest to

I know the 305 grain I loaded up for my .458 flew very well grouping right at 1 Inch. And that was with very little playing around with loads. I could probably get it even better. I have yet to have a chance to get out and shoot some of the 250's that Ron just tested for accuracy out of my .50 TC but I soon will. I'll test them at 150 yards with 100-120gr BH with MMP blacks more than likely. I also have some crush rib laying around that I could try as well.

I am not the best at explaining much - but the bullet works by collecting fluids and fluid like tissue in the flute of the bullet. The flute is wide at the top of the bullet and then narrows to very narrow channel at the end of the flute. The material is collected in the flute and compressed to a very tight stream (like what you can do with a nozzle on your hose). It is then forced through the flute and then up and out. The velocity and volume of the flute in the bullet determines the velocity and the force that the stream has on surrounding organs and tissue.

If you have ever seen a water cutting torch work that is in effect what the bullet is doing.



This picture shows the different XP's and you can see as the caliber increases in size so does the size of the flutes.



Hope this makes some sort of sense.

Ok, so we might just need it in a conical???

I think I understand the tissue damage, but it would also create some turbulence in the air using the same forces wouldn't it? So with those forces exerting on the air it is passing through how can it fly straight and why wouldn't that slow the bullet down faster?

Any reports on shoulder shots/heavy bone?

The entrance to the phonebook is a nice round, but larger than caliber hole, shown in the photo. Some of the other damage down lower is from previous bullet. The next photo shows the hole is now elongated. This is because the bullet tumbled, and ended up facing the wrong way when it stopped.

Yes, with the 305 grain one of the shots Thomas put on a hog that weighed in approximately 140 pounds was a dead broadside heart shot through the shoulders. Another was a quartering away heart shot. Both instances he said the heart was blown apart. Same caliber entrance and a slightly larger caliber exit at approximately 2 inches higher then the entrance. He said the shoulder meat on the entrance was bruised up a good bit around the entrance but the exit wasn't bad at all. Shot was approximately 85 yards on the broadside shoulder to shoulder and the quartering away was approximately 70 yards.

Tx, I am no aeronautical engineer so I really couldn't tell you why they still fly well but so far they seem to fly very well indeed. Now as far as a long range (past 150) goes I really couldn't say since I haven't shot them past 100 out of the AR yet. I will be testing the 250's out to 150 which is pretty much as far as I shoot a smoke pole anyway.

Now is they just made a Colorado legal bullet!

Seems to me that this would cause less meat loss due to trimming than a lead bullet?

Were I hunting Colorado - this what I would use in a heart beat... And I am going to use here in Idaho for our very early 'Green Field' Season.

Most of these like shown in the first picture work very well without knurling a few of them do need to be lightly knurled.

Wonder if this one would knurl up to be a conical?
