Home Forums Reloading Big Game Rifles 358 Winchester Loads

Hey Guys looking for some help. Got my custom 358 win done and I just got the barrel broken in.

The rife showed an immediate preference for the Wisconsin Cartridge Load Speer 180 gr flat nose at 2600 fps over the Hornaday 200 grain factory load at about 2450 fps.

I have Nosler 225 partitions, Speer 220's and 180's, Hornaday 200 gr Spire points on hand.

The rifle is a modern 700 with HS Bottom Metal and Magazine. I can run that bullet out to about 2.85 or so C.O.A.L the barrel is a Douglas premium 1-12 twist 22"

Since it showed a preference right away for the Speer profile, I m inclined to go right after a good stout load with that 220 grain bullet.

I have Varget, 3031, and 4064 on hand, but I can track down other powders fairly easily. Since its such a short bullet I feel I can get away without over compressing a load.

Any help is appreciated. Thanks again!

TAC

51grs with a 200gr TSX gives about 2700fps from a 22" tube.

Will the Barnes open up at 250 - 300 yards. I 've had issues in the past with the tsx not opening in smaller calibers.

How compressed is that load and I m assuming that's a max load since its way over Ramshots loading data.

If I reduced 15% and worked up would that be ok?

Also what was the COAL ON that load?

Sorry for all the additional questions.

I've not used it at 300 yards. Sub your 200gr Hornday in.

I got it from an article that John Barsness did. He used 52grs of TAC for 200gr bullets. If you look at TAC data for the 338 Federal, you'll see they get about 2700fps with 200gr bullets, so it stands to reason that you can sling like weight bullets at least as fast, if not faster from the 358, which is 51grs for me.

Not compressed in the least.

I just ordered the back issue that has that article in it. Hope to have it soon enough. I'm wondering if the TTSX could be used in place of the TSX?

What would also be nice is if Nosler got off their butts and got the .35 cal 200 grain Accubond out again. One can only hope

It's a good article. I've had zero problems switching between TSX and TTSX.

The 225gr Partition is another good bullet for the 358

47.5grs of 3031 and a 220 Speer runs 2440fps from my 22" barreled Hawkeye and is right at 1".


I shoot the 200gr Hornady with 47grs H4895 at 2500fps mainly.

While not a .358 my .35 Whelen likes 225gr. Nosler or Sierra bullets over a moderate charge of IMR 4064. This load should do well in the .358 too.

That's a good load about .5 grains under max right for the 220?

That 200 gr Hornady load sounds darn close to Hornadys factory 358 load. I think they print 2475 on the box!



My concern with the bigger bullets and 4064 is I will run right out of room in the case and have a fairly compressed load? Maybe not. I like 4064 I'll have to explore it thanks!

You'll like TAC more.

I m going to go find some. I was working the calculator and if I go with a 225 grain Nosler Partition and get it moving out of the rifle at or around 2450 fps everything in the world is right.

It would still be running at 1800 fps and 1600 fps energy at 350 yards.

That's exactly what I m looking for right there.

I will add that if for some reason I get to 2550 fps its the same numbers at 400 yards!

I m assuming that Tac data will fall into play here!

48 gr RL-10 sparked by a CCI-250 primer under a 200 gr TTSX goes 2700 fps in Hornady brass at 2.800" in my Ruger all weather hawkeye.

It fires absolute consistent sub inch three shot groups at 100 yards, I wouldn't have concern of bullet expansion out to 400 yards or until velocities fall below 1800 fps, hunting elevations would dictate max yardage.

Since IN now allows 6mm and .30 cal cartridges for deer hunting, I'm not using my 358 Hoosier much. I've got some of the 200 gain Accubonds if somebody needs them, PM me.

And around 46 grains of TAC and a 200 grain bullet works great in that rifle....

I will take them PM sent

I use 51 grs of TAC with Seirra 220 shoots awesome groups and hits like a hammer! Mines a HOWA 1500 .243 rebored to 358 with Timmey trigger 3 groove rifling! Taking it on the 24hourcampfire annual hog hunt next month! TAC is the best in this cartridge I found!

I've had some bullet failures from the Hornady 200 gr SP on deer! They explode ruining lots of meat! That's why I went to the 220!

yeah I think there's and overwhelming amount of support for Tac. I located some about an hour away. Time for a road trip!

I got 2 8lb jugs just in case! Great in 223 too.

+1 on TAC. I use 51 grns in my BLR and shot a medium doe at about 200 yards with the 200 Hornady SP. A pass through that broke the opposite shoulder coming out. I'd like to try the TTSX but haven't yet.

I've shot a lot of IMR 4064 in it and it's a great powder, very accurate but it won't give the velocity TAC will. I used 48.5 and shot this group with the 200 Sierra, maybe 2400-2450 fps.

That's damn good shooting from a BLR!
