Reloading the
.458 Lott Magnum

      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.

Collet Resizing Die

"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.

      This ONE die and collet is universal and works on ALL of the popular belted magnum calibers including:  .257 Weatherby Magnum,  6.5 Remington Magnum,  .264 Winchester Magnum,  .270 Weatherby Magnum,  7 x 61 Sharpe & Hart,  7mm Remington Magnum,  7mm Weatherby Magnum,  7mm STW,  .300 H & H Magnum,  .300 Win Mag,  .300 Weatherby Magnum,  . 308 Norma Magnum,  8mm Remington Magnum,  .338 Winchester Magnum,   .340 Weatherby Magnum,  .350 Remington Magnum,  .358 Norma Magnum,  .375 H & H Magnum,  .416 Remington Magnum,  . 458 Winchester magnum,  .458 Lott and several wildcat cartridges.   There are no extra collets to buy when resizing any of these calibers.   This unique Belted Magnum Collet Resizing Die is only made by Innovative Technologies, and it's available from this website.
