I'm not sure of the laws regarding home loading ammunition in Africa so this could be a no go from the start? But are there any members here who shoot cast bullets in their big game rifles? I think it's quite a big thing in the USA? I don't suppose it's the best idea for really tough, dangerous game but for plains game it would work? But is it a common thing? It's certainly a good way to keep ammunition costs sensible on less important quarry and targets. I've priced 500gr Lott ammo at approximately 85p per round, factory ammo is maybe five times that and just a basic jacketed bullet costs about the same as the whole cast load. When you look at all the animals killed with the .45-70, it seems like a good approach. Big game rounds look to be very easy to adapt to shoot cast. They have weight and don't need huge velocity, so fairly soft lead bullets should shoot well. Apparently the throat on the .458 Mag is a bit long to magazine feed cast bullets well but the Lott is better suited? I'm hoping that's the case!
