What do you guys think of the petals breaking off of Barnes type bullets? (or GMX) Would that keep you from shooting them? If a new bullet came out with a similar design but improved, but the petals broke off after going through the vitals, like in the offside hide, would you shoot them, or not shoot them just because the petals broke off?

Here are some specs to think about
.30 cal
195gr.
B.C.  .670
weight retention 65% from 2600fps up, 99% 2600 and under.
These would generally be of the long range hunting variety.

As long as the petals where cutting as they went through the vitals I would definately use them.  You have to think of it in the design aspect, they opened and cut as they were suppose to when they where suppose to, doesn't matter if after the games dead and the bullet has past through the petals break off.

I think that is a reasonable compromise for a bullet with such high BC.
 
Still 65% weight retention is pretty good for 2600+ impact velocity, provided the bullet still produces a good wound channel.

With a BC of .670 it would be worth a try.  When you think about it the Nosler Partition and Accubond essentially do the same thing.  The Partition loses the front part and the "stem" or "shank" of the bullet continues on to penetrate and usually exit.  The same on the Accubond, it is designed to expand and lose the front part of the lead and the front part of the jacket is supposed to fold down against the shaft and it continues to penetrate and usually exit.
 
You would be accomplishing the same thing with essentially the same weight retention as the Partition and Accubond.  That's good company there.
 
There are a couple of other factors.  The "killing power" if you will, is really a function of the size of the wound channel.  But the length of the wound channel becomes reduced if the frontal area of the bullet is too large.  BC is a function of the relationship of frontal area to weight so a bullet like the Scirrocco or A-Frame have greatly reduced BC after expanding and attempting to penetrate inside a game animal.  Thus reducing penetration.
 
If the bullet expanded greatly for even a moderate linear distance inside the game it would produce a wide wound channel and then if it lost the petals and continued penetrating to exit, that would be good stuff, best of all worlds.

Expansion has been running in the .570-.630" when the petals stay on. This is for a .308 bullet.

I like the wound channel on the 220 gr Nosler Partition
 
 
Losing the petals may be a calling card rather than a detriment.

  Just wondering.  If the bullet had 4 petals and lost 1 or at worst 2,could that affect straight penetration and depth?

I think it woudl depend on how fast the bullet was still moving.  Probably has the same affects as if it hit bone and deflected.

I generally choose a bullet firstly on accuracy out of my barrel. No good I cannot hit what I am aiming for. I tossed out 200gr Nossler Part for that reason.
Secondly I want some expansion or "bullet fail". I tossed out some locally made bullets for that reason. They were accurate but sliced through game like a surgical blade.
 
So sounds like this bullet could work for me. Big Smile

With a BC of .670, I know a few shooters at the range that would be wetting themselves to try them!   LOL!!!!
