Home Forums Reloading Big Game Rifles 358 Winchester Loads

One of my builds this semester is a short 358 for hunting in thick woods. How do you think this load will work in a 20" tube at, say, 25-50 yards?

I've tried the 51g of TAC with 200g TSX, but only got 2400 fps. If you can get the 2700 fps that should be a dandy load.

2450 out of a 19" tube with 48gr of TAC under the 200TTSX. Took several bears with that load, DRT. Don't know that an additional 2-300fps would have made any difference.

That load should work very well in your rifle. Can't imagine anything would not be DRT at that range. Heck of a good load for a 358!

52.0gr TAC with the 180 TTSX was clocking at 2500-fps or thereabouts from my Model 7KS....not super fast, but plenty accurate.

What distance and how well did the bullets open up? Everything I hear about the TTSX or TSX is the faster you run them the better they work. The higher velocity should get them to open up better at further distances then. I have only killed a Caribou and a elk and an antelope with TTSX's from my .338 WM. 225g running ~2800 fps. It did an ok job on the caribou at 400 yards, but shot placement was bad so had to shoot again. The elk at 70 yards and the antelope at 250 didn't need another.

Not to side track this thread but......

I have 200 WW 358 win cases I'm going to sell. 100 are virgin, 100 once fired. If anyone has interest before I list them, drop my a PM.

Bought them for my 338 Fed and decided to go with necked up 308 brass in my rifle.

I understand the high velocity theory with regard to the TTSX's. If I think I might have a shot over 150yds, I carry a Whelen, 300WSM, 270 or 6.5CM. So I'm not really concerned about the TTSX opening up at longer ranges. Shots at bears around here are always 40-50yds max. The TTSX performed as expected and didn't make a mess of the shoulders. Which is another reason why I like them.

Thank you

That is weird. I switched to the 300gr TSX in my muzzleloader this year for deer and noticed the same thing. They flip over backwards and die, but when I skinned them there was much less damage than I expected.

i started shooting the TTSX's a few years ago in a couple other calibers, noticed the same thing...they cut a mean hole you can see daylight through, good expansion, but less bloodshot meat...

Details on that?! Cartridge, bullet, velocity

Wowza.......

I'll guess a 358 cal. 200gr TTSX around 2700 fps, those are the holes I spoke of earlier, I've seen plenty, and they never fail to impress.

My BLR liked H4895, I didn’t try TAC in it.

My 700 also liked H4895, I didn’t measure velocity. I switched to TAC after re-reading MD’s article same accuracy between the two. I suspect higher velocity. Maybe when the merry little breezes blow from the south a while I can get some velocity readings. Snow is as high as 10’ in my yard/range.

There’s been a few different articles on the 358 in Handloader/Rifle over the years. None included the rifles I have/had. But MD’s article was with a Ruger 77, which is the rifle that seems the best fit for my rifles.
