Home Forums Hunting & Shooting Express Rifles and Big Bores Only My .500 Jeffery Problem

If I could squeeze the .505 Gibbs from .640" base to .620" base diameter, then trim the rims down to .620"
and shorten the brass to 2.750" and size and fire-form in a .500 Jeffery chamber,
I would call it the .500 Jerry.

I got mixed up on the date I fired that Sterling Davenport .500 Jeffery.
It was in 2006, and it was actually 107 degrees F in the shade, outside OK City.
I have a record of all 5 shots I fired at 50-yard paper target, open sights,
3 with the fine bead in one hole,
then I flipped up the H&H-style "moon bead" and took a target hold on the top of that bead too, for the last two shots.
The bigger bead made those shots go lower and spread.
That must be the best iron-sight shooting I ever did,
and I recommend this load as an accuracy load to try in a .500 Jeffery:



That was for beginning to sight-in my fellow gunnutt's new rifle.

Here is the sort of beads used, though shown on another rifle:
