Both myself and
River Rat on here have used the 358 Norma Mag for the past 30+ years. While certainly not for the faint of heart, it is a very fine big game cartridge. You very quickly realize that there is quite a difference between a 250 gr bullet at 2500 (edited to correct velocity) and one at over 2800 fps, which is easily obtainable in the Nine Norma.
Garry's rifle is built on an '03 Springfield, weighs right at eight pounds all up with scope sling and mag full of ammo. It has more than 2000 round down the barrel, and still shoots under an inch at 100 yd. IIRC, neither of us have ever lost an animal with this cartridge.
I have sold two 358 Normas to guys on this board. Both of them have been very pleased with their rifles. I have often wondered why more guys don't rechamber or rebarrel to this truly great round.
