The new powders, RL-17 and Alliant Power-Pro 2000MR, have done wonders for the .308 case family of cartridges. I can't seem to find anything for the .358 though. Has anyone got some load data? Perhaps if someone has the "Quick Load" program they might run some recipes for the 225 bonded bullets as well as the 200 gr homogeneous bullets please and thanks.
Await you replies.
 
Not familiar with those powders, but please note that the 358 does not sue the 308 powders. It is a larger bore so uses powders a step faster. For example, you can use 3031 for a 200 gr bullet in 358 but the same weight bullet in 308 wants a much slower powder - say 4350.

That said, there might be other new generation powders well suited to the 358. I load mine with H335 because it works well, its cheap and meters perfectly.
 
I use IMR 4198 with the Hornady 250 grain, Rifle is a Ruger Frontier 16 1/2" barrel. Accuracy is sub MOA and very consistent.
 
For quite a long time I used 358W as my primary hunting cartridge. The best results with medium weight bullets 200gr-225gr was with "casefull" powders; TAC and AA2520 useing Win WLR primers and Win brass.
 
Out with my 358 hawkeye and a chrony yesterday, 225gr. Accubonds 46gr. Benchmark readings were- 2464,2451,2450 fps. Win LR 2.82 OAL Managed 1.5" group @ 100yd.
Nosler PT's 225gr. 46gr. Benchmark readings were- 2414, 2406, 2386. CCI BR 2.78 OAL.

The surprise of the day was the 250gr. Speer @ 2400 fps with H335 and Win LR mag cap. This load is my most accurate to date but a punishing and maybe 1/2 grain over Speers #14 book max.

I have heard MR-2000 is disappointing in the 358 from an Alaska forum. If true it is really is to bad I had high hopes of trying some after seeing some data with it and the 338 fed with a 225gr. @ something well over 2500 fps.

Tac I would love to try but can't find any around these parts and RL 17 would strike me as far to slow.

As for 200gr. homos I'm to cheap to bother. But have good luck with Hornady 200gr. SP and RL 7 getting 2560 -2570 fps with decent groups it's my deer option.
