My Custom 9.3x62 Journey

Photo included was provided by Dayne Horrigan - Scrub Bull hunted with 250gr Atomic 29 Monolithic bullet.
After reading about these bullets in the ‘9.3x62 Journal’, following Dayne Horrigan’s fantastic adventures in Cape York up north, I have recently trialled Atomic 29 monometal copper projectiles made in Australia.
The Oz Atomic 29 250gn bullets seem to perform on par with Woodleigh 286gn bullets. I use these bullets for heavy hoofed game like Water Buffalo and Scrub bulls (feral cattle) with great effect.
Like the similar Barnes X bullets (which I have not used) I have found the 250gn Atomic 29 bullets very reliable penetrators on heavy game at all practical ranges.
The additional benefit of these bullets is the flatter trajectory due to 800m/s (2624Fps) starting velocity. I have been told by the manufacturer of Atomic 29, Cameron Strachan, that these bullets will reliably expand at longer ranges, which until recently, has been restrictive for the Barnes X bullets.
*Cartridge Comparisons
338 Win Mag
Hunting scrub bulls and donkeys, I have used my 9.3x62 in tandem with my Sako AV .338 Wi******er Magnum. As you know, preference is a personal thing, I found that the r***es were quite close in weight, however the .338WM exhibited significantly more muzzle blast and felt recoil, which more than offset the advantage of slightly flatter trajectory out to 300m.
The cartridges performed similarly when using Woodleigh projectiles (.338 Win Mag 250gn vs 9.3 286gn) however, the 9.3 may bump them a bit harder in close. Consequently the .338WM has been moved on.
*308 Norma Magnum
When comparing the 9.3x62 to a .308 Norma Magnum on a recent hunting trip with a friend, the comparison had very negative outcomes for the .308 Norma as the bulls always took several back up shots to anchor them. These shots were taken 0-100m mostly on moving bulls using 220gn Woodleigh bullets which were penetrating adequately however, the impact reaction and the follow up run, took them hundreds of metres away. I thought the 300 Magnum class cartridge was insufficient for this sized animal in all but perfect shooting situations.
*416 Taylor
In addition, I use my ’98 .416 Taylor on water buffalo and scrub bulls occasionally. I find the .416 Taylor generally more decisive, however my lighter 9.3x62 supports the old 9.3 vs .375 H&H argument, as it [9.3] handles more fluently for quick, running shots.
At 0.5 kg lighter, it is less of a burden to carry all day.
