That is the result of impact with AR500 steel. In an animal impact, expansion would stop at the end of the hollow point. That bullet is expanded all the way at to the boattail.

The copper quality issue was limited to .338, .224, and .243 bullets, as it was only in 1/4" and 3/8 bars. I do think the results would be much more controlled at a more reasonable impact velocity. Only time we've ever seen crazy damage was from a guy running a light bullet in a RUM at 3700...

AB lists the G7 of the 177 HH at .237. I'm obviously probably biased, but doesn't shooting a heavier bullet with a lower b.c. to slow it down negate the whole purpose of the build? What's causing the ridiculous damage is velocity. Which was the purpose of the AM to begin with.

The only other difference is on the Super Bulldozer we drill the hollow point .025" deeper, just so that we can get the broach in another .025". The deeper you broach them, the better they open. Unfortunately you can only broach so deep. Once the chips start piling up at the back of the hole you...

I believe these are the 150gr, cause they're easier to stop. The 205gr may open a little more at low velocity due to the thinner ogive. But trying to get a 205 to stop in 2 gels could be a challenge.

The bullet fired at 1689 still exhibited 1.5 caliber expansion

This is about a perfect twist for that bullet.

Attached is what we like to see for high speed and low speed expansion. We try to keep the petals on if at all possible. This keeps the frontal diameter bigger, and transfers more energy, and causes more damage. This is a little bit less so in the Super Bulldozer line, as the ogives are longer...

That depends on a lot of things. Where do the petals go when they come off? What do they hit? How much damage is the small shank doing when it continues on? Keep in mind, animals are not made out of gel. For instance let's take the R.I.P. pistol bullet. It spits petals off about 3-4" into 10%...

Yorke, are these tests in 20% gel? We've tested them pretty extensively in game and in gel. I've found the 20% gel to be harder on bullets than game animals is. We usually run a 10% gel block in front to see how they're going to open and what the wound channel looks like, and a 20% behind it to...

150gr BD II from the TC Contender

More than just some time. Lol. This was about a 6 year project.

Here's a picture of the square with a little girly hand in it. The first pic those bullets are sub 6".

Wedge, the star is rotary broached in the lathe, so it is on center. Nothing is done outside the lathe. All one operation, for concentricity.

I assure you I'm watching this thread closely. And we're working hard on the tip alignment. Highdrum hit the nail on the head. The tapered hole in the new bullets does not align the tips as well as the old hollow point design did. We've made some strides in the last couple weeks. We're also...
