Sir Jerry had a load for Geraldine with Trophy Bonded Sledgehammer Solid 500-grainer, single-fed,
may have been a bit longer than 3.340" COL, but still fit nicely in Geraldine's shorter-than-SAAMI throat.
2325 fps and no signs of pressure with his .458 WM+ load in this rifle.

The shorter-than-SAAMI throat and minimum groove diameter (0.458") of this ".458 WM Special"
might explain Geraldine's speediness and accuracy,
though one might guess pressure might be over 60,000 psi,
might even be as high as the MAP of the SAAMI .458 Lott, heh-heh-heh.

So any comparison of 1:14"-twist Geri to 1:10"-Freki will have to bear in mind the throat difference too.
More than one variable !
Better to compare both Geri and Freki to the Cabela's Super Grade .458 WinMag of all SAAMI standards.
