While ballistically similar to the .45-70, the .450 Marlin was not developed from the .45-70. Rather, the .450 Marlin was developed from the wildcat .458×2″ American, which was based on the .458 Winchester Magnum. This places the .450 Marlin in the .458 Winchester family of cartridges, though it is more easily understood as a “modernized” .45-70. It is possible to handload the .45-70 to levels that can destroy older firearms such as the Trapdoor Springfield. The .Hornady 450 Marlin ammo offers the ballistics of such “hot” .45-70 loads without the risk of chambering in firearms that cannot handle its higher pressure.
The belt has been modified to prevent it from chambering in smaller-bore 7 mm Magnum or .338 Magnum rifles. The .45-70 and .450 Marlin cannot be cross-chambered, but rifles chambered for the American can be modified to fire the .450 Marlin.
Visually, the case resembles that of the .458 Winchester Magnum with a wider belt. The cartridge is most useful for hunting big game at short ranges, being accurate at ranges of 150 to 175 yards (137 to 160 m). The cartridge is capable of taking any large game animal in North America including large elk, brown bear, and moose.
One potential advantage of the .450 Marlin was its ability to chamber easily in bolt-action rifles, essentially becoming a “.45-70 bolt action” cartridge. This idea, however, was only utilized by one company: Steyr-Mannlicher. However, many companies such as E.R. Shaw Inc. and EABCO have helped numerous owners convert their existing bolt-action rifles to .450 Marlin, fulfilling the cartridge’s inspired purpose.

The Hornady LEVERevolution ammunition has revolutionized the lever action ammo. I do so much better downrange at 100yards now. With the heavy 300 grain bullets in the Marlin .450 anything over 100 yards was a wing and a prayer. Now with the new ballistic tip, I can get great groups out to 200 Yards.

I previously used the Hornady soft points which aren’t available anymore (wish they were). This round is more accurate than the originals from my E.R. Shaw rifle. They perform the same. The most recent harvest was a nice hog. It was only 50 yards and blew completely through leaving large holes on both sides. This pig went straight down but no bullet can guarantee that the animal won’t run. What it can guarantee is accuracy, deep penetration, and in this case, lots of blood to follow if it does run after the shot. I feel for those who can’t get these to cycle correctly in their level action rifles. Hornady should address that or offer the original load in addition to this one. I still think this an outstanding round if it works in your rifle.

I have bought and shot the 450 325 grain bullets and love them. I will buy them again next year.

Love this ammo. It makes my lever action Marlin a more accurate and interesting gun to hunt with.

This ammo loads amd functions flawlessly in my Marlin 450 Guide Gun, and extremely accurate and flat shooting with tremendous energy. Cycles smooth as butter. Anyone having an issue I suspect is trying to cycle this ammo in a 45/70.
