The .458 Lott Magnum was
formally introduced as a factory round by Ruger and Hornady in 2003. The case is .300" longer than the .458
Winchester Magnum. Rifles chambered for the .458 Lott can also safely fire .458 Winchester ammo, and it is an
easy job to convert a .458 Win. Mag. chamber to the .458 Lott. However, the .458 Lott requires a longer action to
cycle through a repeater. The .458 Lott was designed by a well known gunsmith by the name of Jacque P. Lott,
for hunting the largest, most dangerous game animals in the world. This cartridge falls between the popular
.458 Win. Mag. and the .460 Weatrherby Mag. The .458 Lott can deliver a 500 grain bullet at 2300 fps from a 22"
barrel, giving it more velocity than the .458 Winchester.
Reloading die adjustments are critical due to the thin case neck. If the crimping and
seating screw adjustments are not set exactly on the bullet cannelure, the case can easily be crushed in loading.
It's best to crimp these cases with a separate operation.
The main problem with handloading the .458 Lott is case expansion that occurs at the
pressure ring "just above" the belt. Conventional resizing dies can't properly resize any belted magnum
case in this area. These cases soon develop a slight "bulge" around the case (usually after just 2 or 3 firings).
When that happens, these cases will begin to stick in your chamber or they will fail
to chamber at all. This is a very common symptom when reloading belted magnum calibers.
Handloading the .458 Lott with our Belted Magnum Collet Resizing Die will increase the
life of your cases and insure a perfect fit in your chamber.
"Finally a resizing die that works on belted magnum cases."
This unique collet resizing die
solves this common reloading problem and has several patented features. The top of the die serves as a case width
gauge to show when "complete" case resizing is required. This resizing die is used to eliminate the case
"bulge" after using your full length or neck sizing die. This die insures that your belted handloads will always
chamber properly. Now your cases are able to last for up to 20 firings, even when using hot loads.
This resizing die uses a collet that fits over the cartridge case, until it bottoms against the belt. The case is
then pressed into the sizing die. The collet allows your case to go farther into the
die where it only reduces the area "just above" the belt.
