This past weekend my son took a doe using his AR chambered in 6.8 SPCII. The shot came at about 65 yds.
The load he used was the Nosler 110 gr. Accubond over a healthy charge of AA2200 powder for a velocity of around 2,500-2,600 fps.

The deer was quartering toward him and the bullet went in at the front of the left shoulder. The bullet hit the leg bone and shattered it. Parts of the bullet came out just behind the right shoulder.

The pic shows the only piece of the bullet that we recovered. The bullet blew-up the leg bone but obviously came apart too.

Was the performance of this bullet a fluke or is the AB not as tough as we are lead to believe? My son uses an ARP barrel which is rifled with 5R rifling and is designed to be more gentle on bullets than conventional rifling.





I was considering using this bullet in the .270 Winny but now I'm rethinking this idea.

Interesting. Please forward the info to Nosler.

I've killed several black bear with the 260 grain Nosler from my 375 H&H, only recovering one bullet. The others all exited.

The bullet I recovered was fired into a good sized bear from about 10-15 feet, and it was in the off-side skin in pretty good shape. The Accubond is designed to have similar performance to the Partition, so it does tend to lose some weight.

That is why I use A-Frames.

Hi Buffalogun :) At the end of the hunt / day you have
meat and this bullet hit some solid bone, other wise its
a .277 110 gr that would have mushroomed & exited !
   Stay safe Joe

I'm with Joe. Not many bullets would hold together after hitting a leg bone at that speed & range.

A 130 grain bullet would be my choice in a .270 Win.

When you hit big solid leg bone at high
velocity with a bullet that has a soft
lead core and a soft thin copper jacket
that is open at the nose and has no center
cross bracing it's going to come apart.

It's just physics man.

If you want to shoot a jacketed lead core
bullet (best cost/performance/availability
balance) then what you could do to improve
results is get a bullet with a crosswise
center bracing built into the jacket
preferably with the lower section having a
thicker jacket. As was mentioned
previously that would be a partition
bullet (although that is not the only
bullet available that uses a cross bracing
like that, there are others sold under
other brands and names).

Your other option is to go with a
monolithic solid. Hard-cast-lead (soft
pointed?), Copper Solids, and Guilding
Metal Solids are your most available
options. The cast lead has no jacket and
we all know that changes things which
requires adaptations. The copper and
guilding metal solids both suffer from the
lower density of those materials compared
to lead.

If cost weren't a factor a lot of us would
be shooting bullets that were guilding
metal jacketed and nosed with a
plastic/rubber tip and tungsten core
insert bonded inside at just the right
spot to give perfect center of balance and
provide even better sectional density then
lead core bullets. But those would be
darn expensive bullets !!!

Don`t overthink it, the bullet killed the deer so it did it`s job. If this was a Rem Core-lokt or Win PP you could say well its a cheap bullet. When a "premium bullet" doesn`t perform like it should its OMG!.... What happened. Every situation is different but dead is dead

Well, I sent the picture to Nosler with a description of
the event and there has been no reply!

Okay.

Hey, congrats on the deer. Sorry you're unhappy with the bullet performance. Seems okay to me.

Am thinking that if you truly want the bullet to hang together completely, go for the Swift A-Frame, or one of the no-lead, copper or gilding metal bullets like the Barnes TSX, or Nosler E-Tip.

I dunno, I actually prefer a bullet that fragments on deer. Likely why my favorite deer bullets have been Nosler Ballistic Tips, and the Berger VLD.

There are so many bullet choices now, there's something for everyone!

Regards, Guy

The sectional density of a 110 grain .277 is pretty low, my guess is it peeled back all the way and that piece of lead popped out but the majority of the bullet exited.
For comparison my wife used a .270 Win with a 110 grain Hornady V-max loaded up to a chronographed 3450 fps on 1 antelope and 2 deer. The antelope was a perfect behind the shoulder hit a rib going in and on exit. big exit hole and death was quick.

The doe she shot was the same.
The other deer was a buck that she hit high in the shoulder. It dropped like a rock. bullet didn`t exit and there was a lot of damage. Had the local guy process it into sausage and salami so I don`t know what happened to the bullet, probably disintegrated.
One might ask why use a varmit bullet on big game....I was given 200 of them and thay turned out to be very accurate out of my wifes Featherweight model 70. I don`t recommend this bullet for big game but they worked
