9.3 bullet test started. pics posted in #1

if that is the case how come that the bullet is destroyed ... not the problem of the expansion but the real problem of cohesion of the bullet. what i can say is the accubond does not like at all water ... which we know even our game are full of.

The bullet was not destroyed in the test. it remained intact but shed some lead fragments from the top, something any cup and core bullets do, including bonded bullets. It also went through both metal surfaces, without expanding at this low speed, which was expected..

ok whatever you want. the minimun expansion speed for the accubond is 1800 fps so it was still within the parameter and the bullet was seen in multiple parts not only one main part ... did you read what we found of the bullet in the test i did ... most of the bonded bullets i did tested stayed into the medium and show a big part remaining ... i cant say the same for the accubond or the ballistic tip ... even the prvi bullet stayed in better shape and inside the medium and it was at the time the cheapest available bullet. other testers in 9.3 has done the same kind of test and found out that the bullet was loosing a lot of material and not staying in one main kind.
it is a cup and core sold as a bonded ...

What is the difference between the Ballistic Tip® and the AccuBond®?

Externally, they look the same except for the tip colors, Ballistic Tip® bullets are color-coded by caliber while all AccuBond® bullets have white tips. Internally the Ballistic Tip® is not bonded and is designed for controlled expansion on medium game with approximately 50-60% weight retention. Conversely, the lead alloy core of the AccuBond® is bonded to the jacket. This bonding increases weight retention (65-70%) and slows expansion resulting in deeper penetration and enhanced bone-breaking potential in larger animals.

and now a test done with the ballistic tip for the 9.3x62:

i will post later some sectioned bullets for the 9.3 but not mine.

One think I didn't know about the Accubond and I was corrected by John Barness is that the front part of the bullet is not bonded, only the mid to rear part is.

And this is probably what explains that it shed some lead. This does not make it a failed bullet.

the bullet did not expand, lost most of his/her weight (cohesion) and flattened. the prvi/ppu bullet handled way more that stress without being a bonded bullet.

you can not call it a failure but fact are fact: in that test your bullet did not make it ...

in the sectioned bullet i did not see any difference between the ballistic tip and the accubond in 9.3. the results i have seen is showing a regular cup and core not a bonded bullet at all. we have seen here some bad results depsite good shooting placement on bison with accubon on 9,3 and .375 mostly and issues with high speed caliber like 338 rum and 340 wea with 225 grains accubond. so that bullet is certainly great for specific task but as of today there are better choices, just my opinion.

You are trying to confirm your preconceived idea from a test which goes against them my friend.

you know what i have no preconceived ideas i tested those bullets and the results are on page 1 post 1 ... the test i posted shown exactly the same: a bullet that smashed against a little sheet of metal, did not expand, shed a lot of his parts but use it as it works for you ... the result of the test i posted is not going against my idea ... i do not use them and they re not bonded despite your claim ... they re cup and core nothing wrong with that but do not expect them to be what they re not ... look up what the 270 grains speer bullet did in my test and what do you think about it? seems some people used them in real life with great satisfaction despite a low price. again just a plain cup and core bullet ...

You wouldn't be able to "see" the difference unless you tried to pull the lead core out of the copper jacket and it just fell out, it's bonded with some sort of chemical process. They definitely acted bonded in my 6.5 and .375 bullet test. That being said I've never used them on game.

Hot-Cor is not a bonded bullet. It is made with molten lead inside the brass. Those who claim it is bonded have misunderstood it. But you are the only person I know who claim that Accubond is not bonded. At this stage I think further discussion is a waste of time with all due respect.
 
It doesn't matter to me what any test with jugs of water says.
Real results are on game only, and the 250gr accubond has worked well for me. Many moose, elk and one G-bear when we had leh in northern BC for them. Most accurate bullet I've tried so far too.

that is right it was a bullet test on water and we all can say that the accubond did not like water in milk jugs ...

yes and i do remember that a non bonded bullet: the 270 grains hornady sp rp did better ... but you re right there is no way you can see the chemical bond. the design of the accubond is showing exactly the outcome you got and fair enough they may work on game but like you i never used them ...

No one that I know claims the Hot Cor is a bonded bullet, and Speer has always been very clear that the core is melted lead that has been injected into the cup.

Has anyone had any experience on game or water with the Lapua Naturallis 250gr bullets? I have to shoot factory ammo as I cant reload in my current housing and there is factory ammo availible. I have two boxes of hornady and one box of ooooold rws TUG ready for spring bear but thought Id ask here. There is a good video from lapua shooting the 9.3 through ballistics gel and a piece of plywood and it hold out and mushrooms nice. I did shoot the Hornady on a mule deer with my last husq and went through the brisket and busted the rear hip retireving the bullet from the skin by its hip, held together ok but bullet fragments through out as has been mentioned many times in this amazing thread. I would also like to thank the group for the amazing information preovided through these tests.

hello, im in contact with Erkki Seikkula sales and marketing manager of nammo group that is including lapua, berger and sk bullets and vithavuori and he has confirmed to me that the last generation of the naturalis so the 3rd will expand and keep his/her cohesion from 490m/s to 1000 m/s or 1607 fps to 3280 fps.

i got some of those bullets and will try them in the media at the same time i will do the 30. 200-240 grains bullet tests.

users in europe including scandinavia and finland are really happy on the results on moose and bear mostly but also roe and red and of course wild boar ... they found a way to get an expansion on a very long run.
