issues with 9,3x62 Norma Vulkan - EU wild boar

Hi!
I own a 56cm barrel 9,3x62 rifle, bolt action, and usually shoot 70-150 male boars in selective culling, 0-150m.

I'm frequently experiecing "full jacket effect" when shooting in the chest, usually avoiding front leg bone not to waste meat with lead and bone splinters.
Resulting in good placement often to heart and big arteries but long difficult searches.

Tried PPU 286 with better expansion but negligible accuracy at 100m

someone suggested geco soft point.
any advice?

Hi Frances, generally speaking, heart shots will produce a dead run. I do not know why hunters keep perpetuating the myth that heart shots are fast killing. The results you have obtained speak for themselves. So before discussing ammunition, if you can, try adjusting (experimenting) your aim higher. Also, broadside shots should be kept close to the shoulder due to the way the lungs taper in pigs. In order to cause the most damage / bleeding, the point of aim should be at the rear line of the foreleg and not 50mm behind the leg etc. And yes, you will lose some meat but you will find the pig.

More on this subject can be found here in an article I wrote for Norma some time ago: https://www.norma-ammunition.com/en-us/norma-academy/dedicated-hunting/ammunition/effective-game-killing-part-2

Regarding your Vulkan load. First check to make sure it is the Vulkan and not the Oryx. Assuming it is the Oryx:

If the wound is 9.5 to 10mm (proportionate to caliber wound), then the bullet is indeed behaving like an FMJ and signals a problem with manufacturing.

If the wound is 15 to 25mm in diameter, it may instead tell us that the bullet has expanded but is not delivering a great deal of hydraulic force. There could be two reasons for this, not enough target resistance (local pigs are too small or lean / low shot placement) or velocity is too low in your rifle (noting also that the Vulkan loses speed very quickly). In either case, an increase in velocity (hand loading) may help increase target resistance and promote hydraulic force.

It is of the utmost importance that you study the wound carefully and not make assumptions based on conditioned learning. Forget what all others say and what you have learned and really look at the wound as if it was the first time. If the wound is say 40mm in diameter, then it shows that the bullet has expanded and done as much as it can do at that impact velocity. If game are still running, the options are - change shot placement and / or increase wounding via another bullet design (or cartridge e.g. .30-06 165gr SST Superformance @ 3000fps).

If you want to, you could try the Geco plastic tipped bullet. This has weaker construction than most and generates a large wound via increased hydraulic force (particles encountering water) as well as direct mechanical action.

Another option, is to hollow point the Vulkan slightly (use a wide bit), thereby weakening the copper mouth of the projectile so that it has no choice but to deform immediately.

Otherwise, the only way to really increase speed of killing, especially when shot placement is difficult due to running game, is to lift velocity considerably while using a weight shedding bullet.

OK, I hope that helps. All the best.

Vulkan 232 original ammunition, not reloaded.
every shot placement that doesn t hit spine or foreleg or full shoulder results in dead runs.
worst ammo, worst caliber ever used.
There is no expansion: enter/ exit wound is even difficult to find with minimum external bleeding.

I m trying to have the best stopping power i can have, after some dangerous charges after 300/30-06 SST 180gr close shots.

Re: issues with 9,3x62 Norma Vulkan - EU wild boar
Hi Frances, yes as I wrote on this website, one of the issues with the 9.3 bore is that it is becoming harder each year to find bullets that dump energy on medium sized game.

I think at this stage, it would be best if you make contact with me by email and share photos so that I can properly investigate and offer more accurate help. I have a great deal of experience hunting boar and have guided clients on boar hunts over many years as well as keeping our own pigs. I am sure we can work through this.
