tyk Remington doesn't own the patent too Hevi-Shot. HS is owned by Environmetal. The original agreement was a 5 year exclusive which expired lastyear. Environmetal makes Hevi-13, Hevi-Steel and Dead Coyote etc... Since it is a patented mixture of metal (nickel, tungsten, iron and a few other "ingredients") it can't be duplicated without their consent. That is why everyone else is coming out with their "version" like Winchester with their Extended, Federal with their Heavyweight and now Rem with their "Wingmaster HD". Nitro Ammo company (Nitro Ray) used to have to get his Hevi-Shot from Remington, now it has to get it straight from the sourch which is Environmetal and since they now have the rights back too it (Remingtons exclusive included Environmetal as well) they can charge whatever they want. Nitro took a big price increase this year and I hear another 20% is possible next year.

If you like the Remington Hevi-Shot loads you better buy all of it you can find, because only what is "in the pipeline" the only stuff left. There will be no more built or shipped anymore!
