Now that I feel like the Noslers are listening I pulled this up from some of my bullet testing. Before anyone decides this is a bunch of nonsense I urge you to try the experiments for yourself. It is beyind eye opening that this bullet works so well. I will post a picture (after I take it) of one of these bullets that actualy saved a hunters life that was charged by a bear. He stopped the bear 6' from doing him bodily harm. More on that later. reflex264


Test overview from .416 vs. .450 5/17/07

In this test I decided to use the toughest media I know of which is dry vinyl coated paper. It will generally destroy bullets and penetration is very limited. The two rifles are as different as they can possibly be. The .450 marlin guide gun is a lightweight short barreled lever action. The .416 Rigby a Ruger #1 Tropical SS/ laminate. Typically the .416 makes its living by generating around 5000flbs of muzzle energy.
First off many would consider this a David and Goliath test but nothing could be farther from the truth. The fact of the matter is when fired into dampened media the .458 Nosler 300gr PP generally out penetrates bullets that weigh more than it does even when fired at slower speeds. This has been proven over and over. In my previous testing I discovered that as media tensile strength rises the bullets of similar construction generating more kinetic energy did have an advantage so to my way of thinking pitting a rifle generating around 3000flbs against one generating around 5000ftlbs would help to establish if the 300gr Nosler was truly as good as it acted in softer medias.
The method used for determining penetration and wound channel score was as follows. After the shot the media was examined to determine the position of the bullet and that stack of media would be removed to that point and placed back flat on the surface of the ballistic buffalo and measured. The wound channel observations were made in layers to determine how quick expansion started, peaked and subsided. Since the dry media wouldn't hold the shape of the wound channel like the damp media no true wound volume could be established but reason able description of the damage could be easily observed.
The bullets were removed, measured and weighed. General observations were made on the condition of the bullets. All of the results are free from bias.

I happen to love my marlin 1895 in 45/70. I have generaly used it with a 350 grain hornady bullet.
I have yet to take a game animal with that rifle, but it is a very near MOA load at 100 yards.
Probably not as good a bear bullet as a Partition but I would feel pret well armed if i had to stake my life on that load.
I get about 1950 to 2000. I think I can get a little more, but for my purpose you would not gain much.
But it sure is a fun.

Great report and very impressive test results. Thank you for your time and effort to conduct your test and sharing your results with us.

I sure hope Nosler decides to keep the 458 cal 300 gr PP, its too good a bullet.
