Front sight adjustment on the Kimber.
It seems really unlikely Kimber would deliver a rifle with iron sights that cannot be regulated. I personally have never shot a Caprivi, but they generally have a good reputation...
Is it possible that the point discussed with
bruce moulds earlier could help you
bpcr?
On a DG rifle you are not supposed to just see the top of the front sight flush with the bottom of the rear sight V (like on a handgun - left illustration), and you are not supposed to take a 6 o'clock aim (like on a handgun, or an AR - center illustration),
you want to have the entire front bead loosely resting and fully visible in the rear V, and covering the spot you aim at (right illustration).
You would not be the first
bpcr, nor would you be the last, to line up the front sight "pistol style" or to take a 6 o'clock aim with a DG rifle, and it would really not be your fault if nobody explained it to you, which is the value of this forum ;-)
Think more in term of shotgun sight picture when using a DG rifle: cover the target with the front bead.
CZ Safari Magnum .458 Win Mag converted to .458 Lott
There might be a hint in this statement ;-)
I do not know who did the Win to Lott conversion on your CZ, but it takes more than just pushing a reamer into the chamber. Because the .458 Win Mag is (so) short, it is a notorious finicky feeder in non-tuned .375 H&H length actions. To feed well the .458 Win Mag, the .375 H&H length feeding rails must be adjusted. This geometry is particular to the Win Mag. So, if you have a well feeding Win Mag, opening the chamber to Lott length without modifying the feed ramp/rails is a classic mistake resulting in temperamental feeding of the Lott... Nothing that a good gunsmith cannot address, but there IS a point when it is a lot more difficult to add material to the ramp/rails than it was to remove it...
Which one do you think will do the best job with less problems?
Classic question impossible to answer ;-)
Define "best job"... 25 yd elephant: the double .500 NE; 100 yd buffalo: one of the .458 Lott; 50 yd leopard or lion: let us be tolerant here and create a niche for the .458 Win but truth be told I am not sure why one would own a .458 Win when also owning a .458 Lott, especially since the Lott can fire perfectly well the Win ammo...
The 50 year old .458 Win ammo issues (compressed loads agglomerating in the heat and failing to fully ignite) have been resolved a looooooonnng time ago, but legends die hard, so there are folks out there who dislike the Win Mag. Truth be told it is a fine cartridge, but truth be further told the Lott is better in every respect ... except recoil, which may (?) be why the Win still has a following, not to mention the gezillions rifles so chambered that have not been opened up to Lott...
I hope this helps...
