.....As mentioned the Speer 9.3 270gr seems to let them slip readily.
As posted above, this Speer 9.3 didn't slip.

....still work.
As much as I am a great fan of Speer Hot Cor bullets, there's no denying that Hornady still has a good bullet as well.
I think there was a thread here recently, concerned about problems with the Hornady Interlocks
Here's one taken form a moose my good friend shot this fall.

225 gr in .338 Winchester Magnum, 2800 fps muzzle velocity, one shot at 45 yd, DRT, retained weight 198 gr.

Yes Mike, In my own opinion Hornady did lower their standards on IL by saving on copper and antimony in order to increase the sales of their IB bullets and bottom line. I had bad experiences with new IL too. The bean counters at work once again. I also milled down the various H bullets and found thinner jackets and less evident interlocks inside the jackets (worn dies?).... about lead cores having less antimony I am not sure but lead prices being so much cheaper than tin and antimony there is only one way to realize the savings....My 2c.I think that you missed the point though, they didn't do this prior to the change, and the bullet has obviously been changed. I never expected 100% weight retention, but I would hope that the core would stay with the lead most of the time.Mike
I was one of the people that took part in the previous thread that everyone seems to be alluding to on this thread, so I find it appropriate to chime in here. I have used the 180gr hornady interlock for years in the 30-06, and up until this season it seemed to do very well; holding together, and generally exiting through the off side. Prior to buying a large quantaty of the bullets with the ID ring taken off (the current manufacture) I called hornady, and asked if anything else in the bullet had been changed at that time. The person over the phone said that only the ID ring had been changed, and I took his word for it. I didn't take a elk last year, only taking a very large whitetail, and paying no attention to how the bullet performed. Upon taking my elk this year, I noticed that neither of my bullets exited (different from previous experience), and neither bullet retained it's core. I had a buddy shoot a whitetail this year with new manufacture interlocks in a 30-06 as well, and he got the same results. I happened to have an old manufacture 180gr interlock around the house, so I took both the old manufacture interlock, and one of new maunufacture and found obvious differences in the 2 bullets. First and foremost, when I halved the old bullet, the core stuck to the jacket.........the new one poped out even before I had it totally seperated. The jacket is visably thinner up front on the new bullet; so much so that the expansion grooves seemed to be only token markes on the new one vs the deep grooves that where on the old, and the cannular was ovviously shallower on the new bullet. I sent the two sectioned bullets, one of the failed bullets (core only), and an unfired new manufacture bullet off to hornady as per my post failure discussion with a hornady tech, back to hornady.........I have not recieved a reply. I know nothing about the current manufacture bullets of other diameters, but the current manufacture 180gr interlock has definitely changed, and not for the better in my oppinion. I have now moved to the 168gr barnes TTSX for hunting; having to accept the inflated cost.

Looks exactly like bullets recovered from snow, either that or the impact velocity was under 1500 fps and shot into something soft?????
Perhaps you just might be overthinking stuff. I took two bulls, one with a .444 Marlin and another with a .338WM. Both dropped stone cold dead, one at 90 yds, the other at 384 yds. Both Interlocks saw complete separation of the cup and cone, but at the end of the day, I was weighing meat, not lead retention. Perhaps you might think that Hornady gets innodated with such calls as yours. My question would be "did the animal drop dead?" Should your answer be "yes" but....but....., then the last thing that you'd hear would be "click".![]()
At the risk of over thinking the problem, to my way of thinking a bullet that fails to hold together or one that doesn't retain its weight fails. If I can make a bullet fail, I won't use it on game because it doesn't meet my requirement of having a reasonable expectation of killing the game with a single shot from any target angle within the range limitations of the cartridge and shooter. If the core separates from the jacket, or if the core breaks, straight line penetration is compromised and the resulting wound channel is shallow or erratic. There are so many good bullets out there, I don't need to use a marginal one in the field, although they are affordable for practice.
I wanted a 220 gr load for my .30/06 and the 220 Hornady was one I tried. Based on my observation of seeing these bullets break up in snow banks, I concluded the cores are too hard and brittle and the jackets are too thin. There is no reason not to use pure lead in a jacketed bullet. Pure lead flows nicely on impact and isn't prone to breakage. There are many ways to keep the core and jacket from separating, a tapered jacket can be used to control the length of expansion, the core can be bonded, or some sort of mechanical locking devise can keep the jacket and core joined, but bonding is the only solution if the alloy core is hard. In the end I chose the 240 gr Woodleigh for my rifle which has the characteristics I prefer and I load 180 gr TSXs in my wife's rifle whose 1:12 twist won't stabilize the long 240 gr slug.
It appears that my issue has made it over to 24 hour campfire. Someone actually stated that the bullet failed because it hit the animal in the wrong spot..........hhhmmm??? To be absolutely cristal clear, I used to recommend Hornady Interlocks to others, because they used to hold together quite nicely; it doesn't appear that the 180gr interlock does so any more.......I no longer recomend them My plan is to keep the ones that I have, because I will soon be recieving another 30-06 that I plan to do a lot of plinking with. At this time I have not as of yet heard from Hornady regarding the package that I sent.
