Rhino Solid Shank – .458″ – 300gr – Bullet test

The .458″ Rhino bullet test this time! The Rhino Solid Shank!

Rhino bullets are designed in South Africa. They wanted to design a “no-nonsense bullet” which would be suited to the harsh African conditions. By the manufacturer, the Rhino Bullets have been designed and constructed to stand up to anything you throw at them, and yet retain the accuracy required by a benchrest shooter. More information about the Rhino bullets, you can found on their homapage: https://rhinobullets.co.za

We want to thank you the P&H EsVo Group Oy for possibility to test the Rhino bullets in our Hard-Hitting Shooting Lab. You can found Rhino bullets on their online shop at https://www.esvo.fi

But to the results!

Rhino Solid Shank .458″ 300gr bullet.


This bullet is one of the so called “Scandinavian edition”-bullets. Testing was made by reloading the bullets to the .458 Winchester Magnum & .458 SOCOM cartridges. We measured the impact velocities ca. 5m from the muzzle. The fastest impact velocity was 724m/s (2375fps), the second fastest was 617m/s (2024fps) and the lowest impact velocity was 574m/s (1883fps).

In addition to these three impact velocities, we also tested this bullet with the velocity of 538m/s (1765fps). The bullet fully penetrated the 120cm (47,2″) of wet paper, a big water jug and a two inch thick wood. The hole at the wood was the size of the caliber, so the bullet did not expand at all. Unluckily, we did not find the bullet at the rear terrain.

We do not know the ballistic coefficient of this bullet, but it MIGHT be somewhere around 0,225 (G1). So if the velocity at the muzzle is 724m/s (2375fps), the impact velocity of 617m/s (2024fps) simulates the impact at the distance of 88 meters (96 yards). The impact velocity of 574m/s (1883fps) simulates the impact at the distance of 126 meters (137 yards).

The impact velocity of 538m/s (1765fps) simulates the impact at the distance of 160 meters (174 yards). At this distance, the bullet would not have expanded at all.


Rhino Solid Shank is specifically designed for hunting. It has a copper jacket with lead core. The lead is bonded to the copper jacket and the bottom half of the bullet is solid copper. It is designed to form four mushroom petals that produce a large but controlled wound channel.

This bullet is made for the .45-70Gov caliber, so we wanted to test it with little wider velocity range, because there is also older trapdoor- and lever action rifles available for this caliber.

This bullet will start expanding somewhere between 538m/s (1765fps) and 574m/s (1883fps) like the test is showing. This is little tougher bullet than some of the competitors, and that is good to keep in mind, if someone is reloading this bullet for trapdoor- or lever action rifles. We believe that this bullet can take even more beating, than what we pushed it on this test. With the impact speed of 724m/s (2375fps), the retained weight was still almost 100%, even if the expansion was quite extreme.

The amount of expanding on the tested bullets was at the good level. Width of the all three expanded bullets are on the same level (1,8x), even though the impact velocities varies almost 150m/s (492fps).

Retained weights of the bullets was almost 100% and of course at the excellent level.


Test targets were wet newspapers. The bullets penetrated as follows:

  • With impact velocity of 724m/s (2375fps), penetration 63cm (24,8″).
  • With impact velocity of 617m/s (2024fps), penetration 45cm (17,7″).
  • With impact velocity of 574m/s (1883fps), penetration 46cm (18,1″).

The wound channels can be seen below. The harder impact of faster bullet can easily be seen from the cavitation. At this case, the fastest bullet penetrated the most.


The bullet that I could use at the moose hunting in Finland with a modern 45-70gov, .450 Marlin or .458winmag rifle. Those would definetely do the job with this bullet. You can expect nice expansion and exellent retained weights when the velocity range is ok.

Like we wrote previously, this is little tougher 300gr bullet, than some of the competitors. Our opinion is, that you should keep in mind the impact velocity range, when reloading this bullet. How much velocity you can achieve with trapdoor rifle for example? What will be the working distance area of the bullet?
