180gr Speer GS length

[Alaska]

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.

Midway says they are 1.16 in long.

JBM also lists 1.16".
