Hello Haggis01,
The 220 gr round nose .30-06 is one of the best Limpopo PG choices, in one old man's opinion.
However, I do not have experience with Sako brand ammunition specifically.
Once I spent 30 days in Limpopo, with Hannes Swanepoel Safaris and my constant companion was a Brno ZKK in .30-06 / 220 gr Hornady round nose softs (had a few solids as well but did not fire them).
The .30 of any sort is not my idea of the best eland caliber, and I did not shoot an eland with it but, had I done so, I expect it would've worked just fine.
In the Lowveld I shot several blou wildebees cows and one bull, plus a fine black wildebees bull (in the Highveld) with that load, plus impala and similar lesser fauna.
The point?
Knowing what I know about Sako products, I expect that the Sako bullet is at least as good as the Hornady, perhaps better/tougher.
If I ever decided to use a .30-06 in Limpopo again, I would once more choose the 220 grain bullet.
It is a classic African bullet weight in that cartridge, and I do not see how you can go wrong with it, Sako brand or otherwise.
You must keep well,
Velo Dog.
