Reloading the
7mm Remington Magnum


      The 7mm Remington Magnum was introduced in 1962, and it's the most popular magnum rifle cartridge of all time.   This cartridge is loaded to 52,000 cup, and its recoil is similar to shooting a 30-06 with heavy bullets.   The recoil is much more managable than most of the larger magnums, and this is a very flat shooting cartridge.   It's easy to see why the 7mm Remington Magnum is so popular.   I have seen spectacular long range accuracy from shooters using 140 - 160 grain bullets, and this cartridge does well with standard or magnum primers.

      The main problem with handloading the 7mm Remington Magnum (like all belted magnum calibers) 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, and they 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 any belted magnum caliber.   Handloading the 7mm Remington Magnum 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 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 made only by Innovative Technologies, and it can be purchased from the homepage of our website.
