I have used the same 30 06 on six trips to Africa for plains game from Steinbok to Eland and Giraffe. Using 180 gr Accubond in Namibia and 200 or 220 grain partitions in Limpopo on Giraffe and Zebra cull. Over 100 animals and no reason for me to consider any thing that the 06 has not been more than adequate for. I don’t like recoil that a Magnum produces for what ever advantage using one over the 30 06 brings. I own 7Rem mag, 300 mag and lastly a 300 Wby mag( my second and definitely my last)..
