Heavy 450 Marlin Ammo - 430gr. LBT-LFN (1,900 fps/M.E. 3,446 ft. lbs.) - 20 Round Box


This 450 Marlin ammunition is safe and is designed for use in ANY/ALL 450 Marlin firearms in normal operating condition.

We always use factory stock firearms to determine our published velocities, so you get true, actual field velocities with our ammo -- not exaggerated long laboratory test barrel velocities.

1.     Item 22A (430gr. Hard Cast Penetrator)

  • 1901 fps Marlin 22 inch barrel
  • 1860 fps Marlin 18.5 inch barrel

2.     Item 22B (405gr. JFN Expander)

  • 1974 fps Marlin 22 inch barrel
  • 1930 fps Marlin 18.5 inch barrel 

3.     Item 22C (500gr. FMJ-FN Barnes Buster Penetrator)

  • 1600 fps Marlin 22 inch barrel
  • 1558 fps Marlin 18.5 inch barrel


You'll note that these 450 Marlin loads are generating slightly lower velocities than their 45-70 counterparts. This is because the 450 Marlin brass (as made by Hornady) has a heavier web  and as such the powder capacity was lessened, so the amount of propellant we can fit into the case is slightly less than with Starline 45-70 brass.

Item 22A -- utilizes a flat nosed hard cast non-expanding bullet that will penetrate 5 to 6 straight line feet in muscle and bone.

Item 22B -- utilizes a bullet that expands to an inch or more at our velocities and hence penetration is limited to about two feet in flesh and bone. This is the single most effective hog and black bear load ever devised in 450 Marlin. I won't use it on animals weighing over 800 lbs as it won't give adequate penetration at bad angles for animals for animals over 800 lbs. If you'll limit yourself to broadside (double lung) and CNS hits, this load will work on animals up to 2,000 lbs.

Item 22C -- utilizes a FMJ-FN bullet designed to penetrate 5 to 6 feet in flesh and bone.
