Home Forums Hunting & Shooting Express Rifles and Big Bores Only The great 458 Winchester. Everyone should own one at least once

Sir Tony,
A triple for me too, to Sir Jerry's health.

Here is the rest of the poop on Geraldine aka Geri:
The Leupold QR mounts were loose, and the rearmost screw was stripped.
This will be fixed by J-B WELD of some steel Weaver bases onto Geraldine.
The rear bridge base holes as present will not allow enlargement of the 6x48 to 8x40.
Since Sir Jerry was getting by with only 3 of his 4 base screws working,
I think the J-B WELD and 4 new 6x48 screws will do.
Geri will be solidly sighted.

The set of Leupold QR bases and low rings weighed 5.013 ounces total for front and rear.
Removing these and replacing with a set of steel Weaver bases only (1.711 ounces for the pair) gives a rifle weight of 8# 2- or 3-ounces.
Removing the naval bronze from the bore, now spotless-clean,
made the weight of rifle with scope bases only = 8 pounds and 2 ounces.
That is what my scales say now, and I am sticking to it, heh-heh-heh.

Squeaky-clean bore was lubed with an oily patch (BreakFree CLP) and slugged with a .50-cal. soft lead ball.
Bore was uniformly tight throughout to my feel.
Six grooves
0.458" groove diameter
0.450" bore diameter
1:14" twist.

A SPECIAL THROAT WAS FOUND !
It is non-SAAMI, making it a ".458 WinMag Special."
It is more than twice as long as a SAAMI .458 Lott throat.









Overall Geri is quite SPECIAL.
She is superbly balanced and rugged as it gets.
I expect her to be speedy and accurate.
I like the old Winchester XTR-type rear sight.
Good with peep.
