Grand Slam????

[Big joe]

I check into the reloading room frequently and love the info and various opinions. I have heard many of you talk about your favorite premium bullets but I rarely if ever, hear anyone mention the Speer Grand Slam. I'm curious about this bullet. The price is a little lower, technology sounds good. Have any of you tried the Grand Slam ??? If so... Let me know what you thought. By the way, I shoot a 243 Win, 270Win and a 300 Win Mag.

Thanks for your info in advance.
