Hi everyone,

Does anyone know whether these bullets are hard or soft? Do they work best at 7x57 velocities or 7mm RM velocities? I've got a bunch of them and was thinking about using them in a 7mm IMHSA at 2300 fps or so on hogs, does, etc., but am a little concerned about adequate bullet expansion.

Thanks

Well I have shot the 145gr & 160gr & find them soft. Best used, IMO, in the 7-08 & 7x57, not magnums. At 2000fps impact vel, they should still give you some decent expansion.

I have used the 160 a lot and find it an excellent bullet in both my 7x57 and 7MM RM.

I have used the 145gr Hot Core for many deer over several decades from a 280 and a 7Mag at about 3050 fps. Never saw anything but excellent performance.

I've never lost a Deer to a Speer 145gr Hot-Cor from a 7mmRemMag. Have used a good number of boxes of those bullets on Deer and just never had a problem. Have had a few different 7mmRemMags and the muzzle Velocity varied from 3000-3100fps depending on the rifle and which Powder I was using.

I prefer to Enter the on-side shoulder and have it make an Exit through the off-side shoulder. Very few make it any distance that requires Tracking with that placement.

Also used the Speer 145gr SPBT at longer distances in the same rifles and never had a problem with them either.

Nothing wrong with the 160gr Mag Tip or Grand Slam either, especially if you have an opportunity for a HUGE Trophy Buck.

Good Hunting and clean 1-shot Kills.
