Never been a big hornady fan except for 44 mag bullets. Mainly cause thier support sucks after calling several years ago, try to get an idea of loads for 44 mags and they gave me bogus data that could have killed me, and told me rudely to buy the manual. So I said, screw em, and called Sierra. Was won over instantly. If Sierra ever stopped thier support line, they would go out of business. But anyway, thinking of trying them again. Are the SSTs, Spire points, and spire point boattails the same construction except the obvious polymer tip and boat tail and flat base? Are they are "interlocks".

Wonder why hornady has the wierd weights? 139gr, 154gr, etc.

My experence with interlocks hasn't been all that good...

If you don't drive "any" bullet too fast, "that" bullet will do well, but once they get up to magnum velocity and then hit bone, only the best bullets stick together well.

My experence has been, that when standard bullets are used as above, they expand too far for anything like an "interlock" to work... The jacket seperates from the core, and it's all over....

Yes, some do have good luck with them, but they either aren't hitting tough bone and or they aren't driveing them too fast... (or they have slowed down by the time they get to the target)

I like to carry a gun/load that will handle anything, or any shot that i can legally take. A bigger animial quartering away can take quite a bit of bullet for it to do a good job, i like something that will "at least" break the "off side" shoulder!!

It doesn't take much bullet to kill a deer cleanly on a broad side rib cage shot though, that is, "if that's the only shot" your ever going to make??

Ditto, what DM said about Hornadys. In magnum calibers they don't hold up . They are fine otherwise but still not as accurate as Noslers or Sierras.

Totally agree, but back to the orignal question. Are these bullets interlocks? Made for biggame? Or a better way, are they about the same function as a BT? Will one hold together better than another? Like the Sierra HPBT is supposed to have a tougher jacket than the Sierra SPBT.

BC I think they are made for medium game at best and it depends on what type of "Medium Game" I had miserable bullet failure on a Mule Deer I hit at about 250 yards with a 7MM 162 grain Hornady Spire point boattail out of a 26" barrelled 7 mag . Same hunt miserable performance on a Bull Elk still recovered him but the wound channels were nothing compared to what a Parttiton will do. Called Hornadys customer service and they told me it was designed for Big game and Elk would be no problem. Same deal on a Cow Elk with their 180 grain 30 caliber out of a 300 wthby..poorest blood trail ever seen on one. Shot was right at 330 yards ranged with a Bushnell rangefinder. Not meaning to offend anyone but this is my real life experience with these bullets..maybe they work better in STD calibers but I'll never use them again in a Magnum caliber and based on the performance of BT's and partitions in standard calibers probably no chance I would use them there either.

The interlocks are outstanding performers. They will outperform the Nosler and are very, very accurate. You want long range accuracy with exception nock down energy, the Hornady Interlocks are top of the line.

Could you explain? Are you saying they will not break up and penetrate further than a partition or accubond? I kinda doubt that.

Must be getting a special run of them from Hornady

One plus of them is they are almost as cheap as corelokts.

i've got about 300 of those bullets sitting around the house in 7mm . Everything from 139 grain SST's to 154 grain interlocks. Worst money I have spent on reloading components.
