No nothing at all. Not in flight anyway.


Read every single page of the above link.

After reading the oracle no longer a Padawan will you be..........

As has been stated, bullets do not tumble in flight. High velocity rounds such as M193 and M855 will yaw (turn sideways) upon striking flesh and typically break at the cannelure or fragment creating multiple wound channels.
Opinions vary, of course.

Bullets do tumble in Flight!!!!!!!!
Here is a picture of some ss109 ammo I loaded.
All loaded bullets wieghed and were within 1 gr.
Shot at 25 yards.
As you can see most bullets hit good, the others? Tumbled?
That fast, so soon out of the barrel?
What could I have done wrong in my reloading?
No other bullets I have loaded have done this.
I did not rig this picture.

Wish it was joke, I was prdatr and had quit a few posts but got new comp and e mail so new nick now.
Again no other bullet I have loaded has done this. MB is fine, no witnes marks from bullet hit.
All I think it can be is the bullet itself. I bought 500 ss109 bullets for cheap and think that maybe the core shifted when pulled???? Putting the bullet out of ballance????????
Bullets look to be in great shape. Here is the a pic of my rifle.

if that wasn't staged, its the weirdest target i have ever seen. it must be a problem with some of the bullets. it looks like about 10 rounds shot a two inch group and 5 keystoned all over the target.

Bullets can tumble in flight, I have seen targets like the one shown above, and I have shot some 38 specials that did that, it's interesting to go look at the target and see that part of the bullets went through the target sideways, just like shown above.

ok, but when the question is asked, it's usually about whether they should or not.

Can and Supposed to are very diff :)

Tumbling in flight is really bad!

I understand that the bullet may tumble in flight, but how did those in prdatr1's photo, above, tumble precisely and consistently 90 degrees from the direction of flight at 25 yards?

This photo from the Ammo Oracle appears to show an expected variety of impact angles.

If you look at the photo posted by prdatr1, it clearly shows holes of bullets going through the target sideways at different angles, note that the sideways holes vary in length, which indicates that they didn't impact the target at 90 degrees, but at various angles while tumbling.

I occasionally get a bullet strike or two per magazine that are elongated like these when shooting the remanufactured ammo from Maine Cartridge Co. I attribute it to very low quality (out of balance) projectiles. I have only been shooting current rifle a few weeks, but so far only this brand of ammo has done this. I have not seen this with any milspec ammo; IMI M193, XM193, Q3131A.
