Hi DrMikeI may have to reassess my work with the 358 Norma Magnum. I've been focused on 280 grain A-Frames and 275 grain Woodleigh PPs. They do pack a punch on both ends of the rifle.
I did my homework, and I came to the conclusion that with all the factors considered, the 358 Norma Magnum is one heck of a cartridge. Therefore, I bought an older M-77 Ruger in 338WM, and am in the process to put a new stainless 24-inch barrel on with a #5 Bull Sporter contour. Although research indicated a 26-inch barrel would be better for this rifle, I just can not see myself walking in the bush with such a long barrel. The 24-inch will just work perfectly for me in hunting circumstances. My plan is to use this rifle for larger and dangerous game in North America, as well as larger plains and dangerous game in Africa in countries where the 375 caliber is not the minimum. As I see it, the 358 NM has the same performances as the 375 H&H, but only sacrifices a tiny bit on bullet diameter, however, shoots flatter over longer ranges. Therefore the NM can be seen as an excellent all-around caliber to have, from the prairies of NA up to Alaska, and from the bushveld of Africa to the plains and semi-desert areas of Africa. I also plan to use the Swift 280 grain A-frame and Woodleigh's 275 - 310 grain bullets and feel those are the bullets it will outperform other 35 cal.'s as well as some a little bigger.
