    I recall the 500 gr .458 bullet was significantly shorter than other bullets available at the time such as Winchester & Hornady, due to the denser core; making them a better bullet for the 458 Win mag because the result was more powder space. But by the time I got a 458 Speer had discontinued manufacture and now I have moved on to the 404.

    I shot the 165 grain Grand Slams in my .309 JDJ Contender at a nominal 2,400 fps. No problem with deer sized game up to my Red Hartebeest at 300 yards.

    The old Speer manual showed a 100 FPS advantage over the lead cored soft point. The highest velocity load showed a max speed of 2239 with the lead core being 2120. These are all in a 458 win mag.
