We did a little Sellier & Bellot easter shootout earlier! Thank you for the Aseliike Remes to make it possible! This is the third and last part of the article series that will concentrate on the S&B Exergy factory cartridges. We already published the 6,5×55 and 308win tests and this will concentrate on the 9,3×62 caliber. The S&B Exergy Blue bullet test articles will follow right after these Exergy articles!
Exergy is the original copper made hunting bullet of the Sellier & Bellot. At their homepage , they are writing that the jacket material of the Exergy, is not available. But on the Exergy 30-06 cartridge page, they are mentioning that it is made of 100% Solid Copper. So we cannot be sure about the exact material, but we know that it is a lead free bullet with little round aluminium tip on the top of the bullet.
But, to the results!
Sellier & Bellot Exergy 250gr –9,3×62 Factory Cartridge
Test gun was a Blaser R8 rifle with the 480mm barrel. We measured the velocity ca. 5m from the muzzle and got a 714m/s (2343fps) impact velocity. Manufacturer promises the velocity of 745m/s (2444fps) to the factory load, from the 600mm barrel.
The slower impact velocity was achieved by reloading. If the velocity at the muzzle is 745m/s (2444fps) what manufacturer claims, the speed of 637m/s (2090fps) simulates the impact at the distance of 134 meters (ca. 146 yards).
The working style of the S&B Exergy bullet is to open in five petals and retain its high weight after the impact without losing the petals.
The harder hit, with the velocity of 714m/s (2343fps) wasn’t too harsh for the 250gr Exergy, like it was for the 6,5×55 and 308win versions. Bullet opened all-the-way to the bottom of the expansion cavity, and it did not lost a single of it’s five petals. Which can also be seen on the retained weight (99,4%).
9,3×62 is more close range caliber than the previous tested Exergy calibers, so it is possible, that cartridges are adjusted for the shorter shooting distances. Of course we did not achieve the velocity that manufacturer promises, because of our 120mm shorter barrel. That also can affect to the working of the bullet.
At the impact of the 637m/s (2090fps) the bullet worked great again, and kept all the petals intact as can be seen on the photo above. The retained weight was also again excellent. With this velocity, the bullet width was almost exact same than it was on the harder hit. Only clear difference can be seen on the lenght of the bullet. Also with this Exergy cartridge, we can expect bullet to open reliably even on slightly longer distances.
This S&B Exergy .366″ 250gr bullet is only available in factory cartridges.
Test targets were wetted newspapers. The bullet with impact speed of 714m/s (2343fps) penetrated 64cm (25,2″) of wet newspapers, and the bullet with impact speed of 637m/s (2090fps) penetrated 57cm (22,4″).
The wound channels can be seen below. Both are very classical example’s of the wound channels.
Factory cartridge with a good copper bullet! You can expect good working at the over 100m distances also. Low ballistic coefficient (G1: 0,348) affects the velocity quite fast at the greater distances. Not the bullet for the real long range hunting, but at the normal hunting distances you can expect very good results on big-game hunting!
