I am very happy to hear that gunner500 is in training with his .505 Gibbs.
145 grains of Retumbo behind that slug will harden his shoulder enough to make
his .458 WM+ into a maiden's caress by comparison.
A maiden perfect for caressing any buffalo and plains game.
Keep up the good work gunner500.
His .505 Gibbs ammo:
FN brass solid, X-Barnes Banded Solid, was .509" diameter, now suitable for .505 Gibbs.
