Hi, I will be hunting a blue wildebeest this season in bushveld conditions.
I have the following ammo available at present to choose from:
Norma Oryx 165gr
Sako Gamehead 165gr
Sako Powerhead II 168gr
Sierra gameking 165gr
Federal fusion 165gr
I was considering the Norma Oryx or Sako Powerhead. Will these be suitable?
The other option I was considering is to get Barnes TTSX 150gr.

Of those you list I'd go with Norma Oryx 165 but on the other hand I've got a buddy that swears by Federal Fusion.

If I could expand the options slightly I'd choose Norma Oryx 180 grain as my first option. Personally I like them better than "equivalent" bullets from other manufacturers. It is a relatively "blunt" bullet so stabilises better than many others in a .308 standard 1:12 twist and very easily in a 1:10 twist that eg the 308 Howas come with.

I wouldn't go lighter than 165 grains on Blue Wildebeest in bushveld conditions. I'm not saying it can't be done, I just would prefer not to.

My opinion, I'm sure you will hear other opinions from other members.

Thank you. I used the Norma last season and it worked well in my Howa.

Have a look at the 180gr Oryx performance in a wetpack. The 165gr should perform on par with the 180gr as speed will be up a bit. That is a big mushroom, adequate penetration and the bullet held together.

Thanks, I had a look at the thread. I seen the comparison between the ammo he tested, very informative.
I am leaning towards the Oryx as I had success with it last year.

I would not fault any of the mentioned ammunition, nor would I chop and change my ammo - one rifle, one bullet type, weight - use it. For the.308, use a 165 or 168 gr bullet of of reasonable construction and learn it well, know where it shoots and you will kill Eland to Duiker with correct shot placement.
I do not like premium bullets for the .308 because they tend to be too tough for .308 velocities. I actually question even bonded bullets of 168 gr being used in the .308

Thanks Treeman. My rifle likes 165gr, they work well so I normally use them. The Federal, Norma and Sako I haven't had any issues with. Seems to love Federal though, but I haven't used it for hunting. I have used Norma and Sako.

The Federals work, that is why they still in production so many years later with no real horror warning posts out there, no absolute warnings to avoid them either.
Its a .308, not a thoroughbred tropical parrot that needs a special diet, correct temperature and specific humidity, it is an feral cat that might do a bit better with some cares, but will flourish regardless.
If you were looking for an interesting, fun to learn, be a scientist weapon to reload for, you have bought the wrong caliber.
Use the bullet that groups best and if possible that shoots very well even a grain before and after best load, u know like, shoots a good group with 3 test loads. Try avoid a bullet that shoots real shit with every load except one specific load tiny sweet spot. This will insure that you have good results hot or cold days, in the sun or at night, even inland and on the coast.
My .204 seems to shoot very well at the range down at the coast, but the groups open up inland ?

I ended up using the Barnes Vortx 168gr. Worked well. Wildebeest was shot at 146m broadside, entered from the left shoulder and found under the skin on the opposite shoulder. Wildebeest was found approximately 30m from where it was shot.

A very well deformed bullet, uniform yet ragged. Not that I am a expert, but from bullet recovery, to bullet form it seems almost perfect choice. The only thing wrong is that the bullet was recovered, I want an exit wound, its almost a must.
Please post the images you sent me, they make for good viewing.

The Barnes seems to have performed well.

From my limited experience with this type of bullet, I have found that going lighter often gives better performance.  Retained weight is still close to 100%, but bullet stays mushroom forward and penetrates straighter, often exiting.  This is likely due to better gyroscopic stabilisation of the shorter bullet and higher impact velocity giving faster and more even expansion.

Just an empirical observation.

THIS IS INTERESTING INDEED. The gyroscopic stabilization part !!!!! I knew this, but did not know I knew this. Gerrie Schultz from GS Custom taught me this 20 years ago but I did not click, it is why he always sold lighter bullets than that which could be stabilized. IE he recommended 110 gr bullets for the .270 Win because of what you just said, even though he made 130 gr bullets that would also be accurate. That Gerrie Schultz was a very very clever. VERY !

When he (GS) started turning his original copper expanding bullets (those with the smooth shanks), I obtained some 130gn 308" bullets to test on warthog.  At the time I was culling a lot of them.  They performed well.  Better than I expected for such a light bullet.  Most exited on broadside shots, even when encountering bone.

Then I figured, if the 130gn bullets worked so well, the 150gn version should work even better.  So I odered a pack and loaded them.  The pigs still died, but the bullets did not exit.  Most of them also swapped ends inside the pigs, ending with the base forward.  When I finally met him, GS explained to me the issues with stability and maintaining a straight path through the animal.  Obviously, he had done his test already.

I fear a lot of the current crop of copper expanding bullet makers lack in practical experience with their own bullets in the field and most reloaders just want to stay with a familiar bullet weight when changing from lead core to mono copper.

Does such a lighter, faster bullet cause more bruising, or less?
