I really like speer bullets. I use them in a .243win, 280rem, & 30-06. I like the spbt for the .243, and the mag-tip & grand slams for the 280 & 30-06.
One thing I have always wondered about is all the dislike for the newer version of the grand slam. Switching to a single lead core instead of 2 different ones is what everybody complains about. But now if you think about it, you have the same bullet as the mag-tip with the exception being, the grand slam has the heel lock, making it "better", maybe. Lots have said they like the mag-tip, but no longer like the GS. Makes no sense to me. I have only used the MT & GS on deer and a few bison for butcher with very good results. I Haven't tried them on elk, but plan to someday. I love the 7mm -160gr. magtip & grand slam, and the .308 - 180gr, mag-tip & grand slam. I AM ALWAYS ON THE LOOKOUT FOR THE 180GR. MAG-TIP, wish they wouldn't have discontinued them.
