How do these differ from Hammer or Barnes in construction and/or design?

Barnes is not a turned bullet. I am not very familiar with Hammer outside they are turned. Ours is a turned one peice projectile with a cavity behind tip.

Ok, but I was looking for more terminal ballistic info. Are they designed to peel back and mushroom like a Barnes? Or fragment where the petals break off? What’s the real world min impact velocity for full expansion?

At above 2300fps, you will see front of bullet almost always blown off. Below that velocity you can see front staying attached. I recommend 2000fps on single feed bullets but customers dont always follow that advice. The pictures below were sent in by a customer.
7PRC
160GR Copper Rose Single Feed
3000MV
1120 Yards
1505 impact velocity
Two hits and both expander. One Exit 2.5-3" other 1.5-2"
Bullet performance can vary on impact medium

The petals come off at high velocity impacts, and stay together out further. Not sure where the stay on a come off distance is but the results are good.

What is a single feed bullet?

The wounds shown, and the one bullet recovered are indicative of yawing. There are other pictures where wounds look normal and 1”-2” wide.

Both bullets stayed face forward and expander.

What is a single feed bullet?

Super long projectiles that typically don't fit in a magazine therefore single feed

In these specific bullets, that is not what single feed means.

They are single feed because they have a thinner tip for lower impact speed upset. And the recoil collapses the nose in the magazine on the thinner construction.

So the difference isn’t dimension on the bullet, but thickness of the tip area. In these specific brand of bullet. The single feed and mag feed are dimensionally identical. Just thicker on the nose with the mag feeds which has a higher minimum impact velocity

Both bullets stayed face forward and expander.

Yawing bullet often have some expanded aspects.

This shows swiping (bending) of the petals to the right as viewed-









The wounds are also elongated.


This is as close to a positive evidence of yawing (tumbling) bullet as you can get (expanded front forward bullets do not make elongated, sideways bullets shaped wounds)







Furthermore, solid copper bullets that stay front forward do not create 4-8” diameter wounds.



@SMC_GUIDE you own, or are involved with McGuire- correct?

I am the owner of McGuire Ballistics. Our bullets do stay face forward and expand. After initial expansion they can destabilize and tumble but that is a byproduct.

Ok, thank you.

I answered the question that was asked- the large wounds that you are showing are from yawing projectiles- whether they expand first or not.
Yawing can and will create tremendous wounds-he issue is that yawing is the least reliable form of upset, and looking at threads from users on other forums, shows that the very good wound channel size shown here isn’t what happens consistently.

What is the percentage of your projectiles that yaw before exiting a deer (6-8”)? And, is that calibers/bullet specific?

What are you trying to say/show?

 

[SMC_GUIDE]

The bullets stay face forwardand expand. We have killed thousands of animals and we understand how they function. Thank you for your interest and I will be keeping this thread active as we get more reports in.

Your own pictures show that the bullets yaw. A video clip of synthetic clear gel at high impact velocity doesn’t show anything functional.

Furthermore, clearly the bullets do not yaw consistently by dozens of pictures from users on other forums. Yet, you post here ones that do (cherry picked examples?) and then when asked questions default to “we know how they work”?


About 60 seconds of looking at the McGuire thread. These are what standard monolithic wounds look like- not yawing projectiles, and narrow wound channels-


























These are not point forward wounds from a mono, yet are what you are posting.












I was, and am asking for technical information and clarity on expected behavior.
