Hi
I wonder if somebody has used these bullets or know if these bullets are realy bonded cor or they'll separate easily on impact on theboones ?

I cut open a speer hot cor 105g .243 bullet a couple of months ago. It was not bonded (soldered). You would think that it would be hard to keep molten lead from sticking to clean brass, I don't know their method, but they've managed to do it.

I haven't tried the bullets out on game yet, so can't comment there.

Speer's bullets marked "Hot Core" on the box (not ALL Speer bullets are Hot Core) supposedly have the lead cores poured in a molten state into the jacket cup, which is supposed to make them hang together better. The jacket would have to be really clean if any "bonding" were to happen, as Loren noted. They aren't chemically or mechanically bonded.

My experience with them on game has been limited to light-boned whitetails. I have never had a core/jacket separation with any of the Hot Cores I've used (6mm/105 Spitz; 264/140 Spitz; 270/130 Spitz; 284/145 FB Spitz; 308/150 & 165 Spitz), but, did have one with a 284/145 Boattail (their boattails aren't, or at least those weren't, the Hot Core design) on a close range (20 feet) shoulder shot. The muzzle velocity of that load was in the 2850 FPS range, so, who knows what would happen at 3300 FPS from an Ultra Mag or STW.

Speer's Mag-Tips have an excellent reputation for holding together, and the price is reasonable for a low end 'premium' bullet, unfortunately, they aren't available in all the calibers/weights I'd like.

i like 'em a whole bunch, at least those in .311 150-grain persuasion. killed four deer with a mosin-nagant m44 sporter and handloads using the speer at about 2,600 fps. one did lose the front of the lead after going through a foot of ribs and innards, then the offside shoulder joint of a big doe (150 pounds or so). the jacket, with lead base still seated, was just under the offside hide. the jacket was open to about 3/4ths inch diameter. they are very, very accurate, too at least in my experience with the .311 150-grainers and 8mm 200-grainers.

Danny. In the three deer I've shot with the 165 gr. Speer spitzer flat base Hot-core, I've recovered only one bullet. Two shots were broadside and the bullet passed clean though the mule deer. The third deer was facing me, uphill at a laser measured 250 yards, figure maybe 200 actual yards based on the slant range. Bullet entered the chest, angled up to hit the spine, went over and cut two ribs, and ended up against a back leg bone, breaking that bone. The recovered bullet retained 65 percent of it's weight.

As R-WEST observes, the Speer boattail (and any other conventional boattail as well) does not hold together as well as the flat-based bullets, due to the internal shape of the jacket cavity. Speer HotCor's are ample for most ungualtes.

I have just ordered 5 boxes of speer 180 gr .308 Round Nose bullets for my 30/06 for pigs this year and I am real keen to see how they do. I am hoping for them to hang together reasonably well but mushroom violently....am I hoping for to much

Ive shot numerous Mulies with Speer Hot cores and used 243 win, 7mm mag, 300 Savage, 30-06 and a 308 to do it. Lucky for me, the deer must have just assumed I was using premium bullets because they have all died on the spot.

I loaded up a whack for a few friends of mine in .303. One fellow shot a calf moose six times from the shoulder to the guts. All the bullets completely penetrated and left quarter sized holes through out. Not much bloodshot either.

Speer Hotcore?



I really wasn't thinking of taking things that far...

I kinda figured just striping his legs with a weed-eater would suffice.
