The ones I have coming, are the spbt, which I believe are NOT the Hot Cores. I'm told that the two fly different, and one is a flat base, I believe, the flat base, is the Hot Cores.That 7mm Speer 145 gr Hot Core is a good deer bullet if you keep the impact velocity under 2900 fps. Had a friend that was using it in a 7mm Rem mag and running it full throttle. Deer would run off a ways and not leave much if any blood trail often when shot inside 200 yards. He noticed that when the yardage got a little over 200 yards deer dropped and those that did not did not go very far and there was a good blood trail because the bullet exited. He decided to load his 7 mag down and found great accuracy right around 2950 fps. Where he was hunting this was plenty of velocity because his max shots would be around 350 yards on a power line cut through a little stand of pines that was between two soybean fields in east NC. He did not have many runners after doing this.
Back in 1980 I used some Speer 150 gr BT Hot Core in a 30-06 for deer and it was an extremely accurate and deadly bullet. The ONLY local place I could get them quit handling them and started using the more popular Sierra 165 BTHP. It was also a great deer bullet so I just switched to it.
I believe they're basically a fusion. Federal owns Speer and the "bonding" process is the same for both bullets. I just ordered some 140 gold dot for my creedmoors. Lets see if they perform as good as they say.I'm wanting to try them in my creedmoor, love to get some for my 7mag for elk but they don't make them in .284 cal
