Excellent rifles to bring to Africa , Limpopo province, South Africa, hunting the bushveld is special, mostly walk/stalk hunts, no long distance shots needed ...heavy for caliber bullets is the way to go...In 1944, the Swedish army switched from 156 gr RN to 139 gr Spitzers. They were getting a skosh over 2500 fps out of their 26" barrels with the Spitzers.
At 762 mps with a 250M zero, you're going to be somewhere around 12 cm high at 100M. If you're hunting the Karoo or the eastern cape mountains, that's probably fine.
Predicted MV for 40.5 gr S365 is 2554 fps, pressure at 42k psi. I expect measured MV will be below 2500.
I said before I wouldn't chase velocity, I still stand by that, but there's also nothing wrong with working up a ladder, start at 40 gr and move up in half grain increments until you get a sticky bolt lift.
My hunting load is 160 gr Woodleigh PPSN, MV 2380 fps (this is what I'm bringing to Limpopo next month, along with my 9.3x62). Both that and my ELD-X 143 loads are exceptionally accurate, so I just didn't bother trying to get any faster than that.
My aim is to shoot good groupings at 300 meters/hitting a 200mm steel gong in the center with small groups.
This will enable me to shoot out to 250-300 meters at a Springbuck in the Kalahari or Karoo regions. When getting these results I will be content.
