I would load 200 grain bullets and keep my shots under 200 yards. It's capable of further distance, but the trajectory will be like a rainbow.
I am constantly amused/bemused/confused when people make "bush gun" statements like that. It makes me wonder if they have ever actually owned a .358, and if they have, if they bothered to look into what it was capable of.
The wife is using 180 grain Barnes bullets for the moment, but they are no longer in production. Suffice it to say that a 180 grain bullet exiting the bore at 2900 fps will shoot with a 30/06 using the same weight bullet to at least 300 yards, and nobody ever complained about "ranbow trajectories" in 30/06's using 180 grain bullets. Nor has the 180 grain, smaller diameter, .30 caliber bullet been criticized for not being heavy enough.
Hmmmm... odd how that works....
If she does use up these last four boxes of bullets in this lifetime, then we'll have to move on to the heavier 200 grain bullets, I suppose.
Will that make the .358 Win into a short range, sub 200 yard rifle? Not hardly. All rifles are individuals, of course, but loading data for 200 yard bullets in the .358 show it will shoot to point of aim at just under 300 yards without rising further above line of sight than +4". That is minute of deer, never mind minute of elk or moose, folks.
One reason the .358 Winchester never caught on was the unending proliferation of myths that claimed it was a nice little "bush gun" cartridge but unsuitable for anything over 200 yards.
The .358 Winchester is a fantastic little cartridge that packs a punch far beyond its' size, with remarkably little recoil (certainly less recoil than .30 caliber rifles firing identical bullet weights with approximately the same velocity). I am more of a .358 Norma guy myself, but the fact of the matter is the .358 Winchester is more than sufficient for 99% of the big game hunting in Canada. I would not feel handicapped if forced to use a .358 Winchester for the remainder of my days on this mortal coil.
And for the reloader, particularly the one also willing to cast bullets, it has unmatched versatility and ease of loading. Actually, if you're only going to stick with factory loads, then you have perhaps found the one weak spot of the .358 Winchester.
I have yet to meet a person who owned a .358 Winchester and didn't think they had a wonderful hunting rifle.
