@Technologist So what was the outcome? Photos? Story? Interested to hear how it turned out in the end.
My father and I went to a superb place near Bloemfontein. It was my first time hunting in South Africa, and it was amazing. The people were great too. Skilled, knowledgeable in their field and very friendly.
To me, this thread was a way to use the collective experience on the board to get a feeling for the maximum performance of my rifle. It is a beautiful, albeit worn, Sako L579 in .308 Win. the barrel is cut to 22.5 " and threaded. I've got a Swedish made suppressor from Stalon on it. It's quite light and manageable and very comfortable to shoot. ( I can't believe some PH:s go through their career standing next to the sticks when the shot goes off, not wearing ear protection! )This was the first time I killed anything with it (although I've obviously shot hundreds of practice shots first, and plenty more to develop a load).
I settled on the 165 gr Hornady interbond, because I've been satisfied with the interlock previously, but I figured that this hunt deserved a little extra in the bullet department.
I shot plenty of the smaller plains game species. Performance from the .308 was absolutely satisfactory. Nice exit wounds, lots of blood. I had good luck with my marksmanship as well. I believe the first three kills were with one shot hits to the heart of the game. The eland and the flakvaark were hit a little too far back, but I got the lungs none the less.
The eland was stalked in an area that alternated between bushy trees about 2-3 meters in height and open surfaces with red dirt. The stalk was very exciting, if a little short. We went for a culling eland cow, and I ended up shooting it from just about 200 meters. The group went off and she kept along for about 50 meters before she lost steam and piled up. Dead when we arrived.
As for the performance of the .308, this was ofcourse not a mature bull, but a decent cow, and the range was 200 m instead of 300 m, but I'll leave a report anyway.
The hit was far back, but to the lungs. Most of the bullet, including the base, stayed together, and was gathered by the good people in the buther shop at the far side of the animal (don't remember if it was in the shoulder or beneath the skin). As I remember it, part of the bullet had passed through (I believeI found a very small exit wound). The part that was gathered wasn't perfeectly mushroomed but it was decently expanded.
I'm very satisfied overall, but I think I'll give monolithic bullets a chance for the next time around. If it would have stayed together just a little bit more then it would have gone through, which I think is a good indication that you have some margin. If I ever end up taking that 300 meter shot at an eland bull, I suppose it would be advisable to not hit the shoulder bone.
The last day we stalked a beatiful eland bull that we never got a shot at. I'm just as happy, as I got plenty of other successful hunts during the week. To be honest, having one failed stalk in the bunch kind of proved to me that the others were "real". Hunting wise, it was an exceptionally successful week, at least by my standards. The whole experience was fantastic.
Thank you all for the advice!
