I need to run thru the calculator to see if it will Stabilize in a 1:12 twist
180gr Speer Grandslam Length .308 Dia ?
 
Wish I could help, thought I still had some but came up empty. I have a 180 gr Mag Tip which measures 1.28" and I remember the Grand Slam being only a tiny bit longer, at least the old 2 core version was.
 
I'm no help for this. I see Mag-Tip, Hot Cor, spitzer, but no Grand Slam. Used to use them quite a bit, but haven't used them in a long time, now.
