trail the only Speer bullets Ipersonally used werea few 110HPs and 150Spitzers in my 30/06 many, manymoons ago and they worked great! I know from experience as well that the GrandSlam is a quality bullet that will do anything a Nosler Partition will do. I have heard much praise of the HotCors as well but can't speak for them personally.

Good luck,
RA
