45-70 Magnum - Lever Gun Ammo
300 gr. Jacketed Hollow Point @ 2,350 fps/M.E. 3,678 ft lbs
20 Round Box



Our 45-70 ammunition is externally identical to SAAMI spec 45-70 ammo, but internally it generates FAR more power and pressure. So, our 45-70 ammo will fit into ANY 45-70 firearm but is not safe in every 45-70 firearm. 

Its use should be limited to the following firearms:

All Marlin 1895 (1895 Marlins are all model 336 actions, chambered in 45-70) iterations made since 1972, all Browning 1885 and 1886 copies, Rossi Rio Grande, New England Arms Handi Rifle, T/C Encore, ALL falling block actions made of modern steel such as Ruger #1 and #3, Shiloh, Christian and Pedersoli Sharps, Henry Lever Action Rifles, all Winchester 1886 iterations made since 1915, CVA Centerfire Rifles and all Siamese Mauser bolt actions.

Never use this ammo in ANY original or reproduced "Trap Door" action as the design is far too weak.

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

Many a Grizzly Bear, Cape Buffalo, Bison and other dangerous game have fallen to our 45-70 loads since we began 45-70 production 1999. Below is an idea of what type of game these loads were designed for.

Item 8A -- for game where 5 to 6 feet of straight line non-expanded penetration is needed.

Item 8B -- the bullet utilized expands to an inch or more in diameter 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 45-70. I don't use it on animals weighing more than 800 lbs as it won't give adequate penetration at bad angles for animals larger than 800 lbs. If you'll limit yourself to broadside (double lung) and CNS hits, this load will work on 2,000 lb animals.

Item 8C -- The bullet we utilize in this load is very tough and gives only a small to moderately sized mushroom (about .60 cal) and because of the smallish mushroom, it penetrates very deep -- about 4 feet in muscles and bone and as such is a great bullet for use on dangerous game and on smaller game too as it does expand some. This load is the most versatile of our 45-70 loads.

Item 8D -- This bullet is a solid and won't mushroom and thus will penetrate 5 to 6 feet in muscle and bone.

Item 8E -- the bullet utilized in this load will expand radically and will penetrate only about 18 to 24 inches in muscle and bone and was designed for use on animals weighing no more than 400 lbs. At 2350 fps it is very fast and flat shooting. (For a 45-70)

The absolute best high pressure load manufacturer in the business. The 8E load does well for me; it is fast, accurate and is a perfect match for my Henry .45-70 H010. Four rounds at 75 yards within 1.5 inches using my Vortex rifle scope mounted on a picatinny rail (Marlin 336 type); in which my drilled and tapped receiver was ready for regarding such an application. I have other 8x loads I will try; just haven't gotten around to them yet. If you want the best; it is worth every penny for these rounds from a elite manufacturer.

Update from my last review on these rounds in January of 2018. I shot these rounds through a chronograph about a week ago. I was shocked at the numbers.! They produced 2,493 FPS average out of my ultra Hunter handi rifle with 24" ss heavy barrel scoped with 3x9x40 slug hunter Nikon. That is so fast for 45-70 ammo !!! Superior product from buffalo bore

I use this round on deer in va it is devastating head on chest shot turned all intels to mush. Good black bear round too.

Second shot, second kill. Can't recommend this round enough.

Just took my first buffalo bore deer. Item 8E. "Expand radically" is being humble. Let's just call it a self-gutting round. Deer is dead, I am happy. Goddamn.

Hello, buffalo bore comrades. I wrote a review back in 2011 on 405jfn, which is still posted. Since then I switched to the 300gr jacked hollow point. Well, this ammo shoots 1/4" groups at 50yds out of my handi rifle with a 24" stainless barrel and receiver, and thumb hole in the stock. These groups are unreal for big bore ammo. This is a credit to the precision and consistency in which the staff at Buffalo Bore produce their ammo. Well as per performance, a few weeks ago I had 1st opportunity to use those 300gr jacked hollow points on a whitetail deer. I was 35 feet up in my summit climber hunting in Mississippi, and a deer showed up right before dark at about 30yds, I put the hammer down, the deer laid down as soon the hammer dropped! !.didnt realize that when I shot I blasted a limb off about the size of large man's thumb, and the 300gr still hit its target. A week later I took an 80yd shot on a good bodied 7pt buck. I was was in a box stand elevated on a hill. When I shot he stumbled then made his way off the food plot. Found the blood trail, massive blood trail he only went about 25 yds, it was a KO! Both deer had about quarter size entry and exit, but when I rolled back the hide, there was fist-size damage throughout!!. The fact is, when I'm in my stand, I'm am so confident and in command with Buffalo Bore Ammo, I would never consider using any other ammo!!

Been using for the last 6-7 years on whitetails with excellent results in my 1895 guide as well as pedersoli double rifle
Just made the switch to a scope on the marlin due to old eyes and looking forward to seeing groups and range i can squeeze out of this ammo

I can't speak for on game performance as of yet, but this ammo shoots sub MOA out of my Marlin 1895 GBL at 100 yards! ABSOLUTELY INCREDIBLE!

Ruger #1 African, Found the recoil to be mild for the amount of energy the round produces. Very accurate. Four large Russian Boars, one buff, six deer, all one shot animals. Very good round. Highly recommend it. Will give it a workout in Africa next year.
Eddie Martin on 11/07/2010 06:01pm
I shoot these in a Handi-rifle and recoil and muzzle blast are unreal. These bullets are very accurate and deadly.I have taken deer out to 200 yards.The 300 gr. h.p. is a monster ! Thanks Buffalo Bore.

yup. they work. I got new floaters in my eyes. need a heavier gun.
Derek Chaisson on 07/09/2009 03:19pm
In October of 08' I first tried these rounds. I was first impressed with the accuracy at the range and even more so with the two whitetails I took in the first weekend. Both were outside of 100 yards and didn't take a step.
