I used the search function and the newest load information I found was over 6 years old. So, I thought I'd ask again and maybe get some updated information. I'm in the final stages of putting together an Interarms action with a 22" pac-nor barrel in 358 Win. I've been tracking down and finding only two different bullets for this new beast - Sierra GK 200 gr SP and Sierra GK 225 gr RN. Some of the powders I have that I've read about working for this include: Varget, I4064 and BLC-2. I also have I4350, I4831, H4831, RL-19. I've read about using W748 and TAC but the latter is like a hens-tooth around here and only occasionally have I seen any 748. What loads have y'all found for these two bullet weights?

The .358's advantages are not based on bleeding edge technology. It uses a decent weight bullet at decent velocity. All I am getting at is even 40 year old data is effective. With today's powder supply use what you can easily get. Use what is so popular it will be manufactured on a regular basis. Those would be Varget, IMR4895 or H4895, IMR4064 and 748. These are way too slow - I4350, I4831, H4831, RL-19. | |||

Bbear I think you have a couple things crossed. The 200 gr Sierra bullet is a round nose and the 225 gr Sierra is a Spitzer bullet. The 225 is a good bullet in the 358. There are several other good bullets on the market. The Barnes TSX 200 gr bullet is great. The 200 gr Hornady spire pt is excellent on deer. The 225 gr Nosler partition is great. The 250 gr Speer spire pt is also great for larger game. I would suggest you do a search on a couple loading web sites. There is lots of new data with newer powders out there. However you will find that some of the older powders such as IMR 3031, 4895 both IMR and H are very good choices. | |||

Bbear: My 22" bbl Ruger Hawkeye averages about 2450 fps (15 foot velocity) with W-W SUPER 200 gr. Silvertips. I've been able to equal that with the 200 gr. Hornady PSP and max. loads (from Hodgdon) of H4895, IMR4895, IMR4064, and Varget. I also got the same with my max. load of IMR3031: I couldn't get the max. load listed by Hodgdon into the case. Accuracy was best with IMR4895 and worst with IMR3031. I've only tried Varget with the 225 gr. Sierra PSPbt. The max. load chronographed at 2400 fps, but accuracy was better a grain below max., and only 20 fps slower. All of the max. loads with the above powders are compressed. Therefore, IMR4350, IMR and H4831, and RL19 will be too slow burning for optimum velocity, given the limited capacity of the .358 case. Varget is the slowest burning powder listed by Hodgdon. Good luck with your new rifle! Cheers, Al | |||

My favorite load was 49.2 grns of I4895 w/a nosler 225 grn partition out of a 20" BLR for 2425 fps Mike Legistine actu quod scripsi? Never under estimate the internet community's ability to reply to your post with their personal rant about their tangentially related, single occurrence issue.  What I have learned on AR, since 2001: 1. The proper answer to: Where is the best place in town to get a steak dinner? is…You should go to Mel's Diner and get the fried chicken. 2. Big game animals can tell the difference between .015 of an inch in diameter, 15 grains of bullet weight, and 150 fps. 3. There is a difference in the performance of two identical projectiles launched at the same velocity if they came from different cartridges. 4. While a double rifle is the perfect DGR, every 375HH bolt gun needs to be modified to carry at least 5 down. 5. While a floor plate and detachable box magazine both use a mechanical latch, only the floor plate latch is reliable. Disregard the fact that every modern military rifle uses a detachable box magazine. 6. The Remington 700 is unreliable regardless of the fact it is the basis of the USMC M40 sniper rifle for 40+ years with no changes to the receiver or extractor and is the choice of more military and law enforcement sniper units than any other rifle. 7. PF actions are not suitable for a DGR and it is irrelevant that the M1, M14, M16, & AK47 which were designed for hunting men that can shoot back are all PF actions. 8. 95 deg F in Africa is different than 95 deg F in TX or CA and that is why you must worry about ammunition temperature in Africa (even though most safaris take place in winter) but not in TX or in CA. 9. The size of a ding in a gun's finish doesn't matter, what matters is whether it’s a safe ding or not. 10. 1 in a row is a trend, 2 in a row is statistically significant, and 3 in a row is an irrefutable fact. 11. Never buy a WSM or RCM cartridge for a safari rifle or your go to rifle in the USA because if they lose your ammo you can't find replacement ammo but don't worry 280 Rem, 338-06, 35 Whelen, and all Weatherby cartridges abound in Africa and back country stores. 12. A well hit animal can run 75 yds. in the open and suddenly drop with no initial blood trail, but the one I shot from 200 yds. away that ran 10 yds. and disappeared into a thicket and was not found was lost because the bullet penciled thru. I am 100% certain of this even though I have no physical evidence. 13. A 300 Win Mag is a 500 yard elk cartridge but a 308 Win is not a 300 yard elk cartridge even though the same bullet is travelling at the same velocity at those respective distances. | |||

I used to own a Mod 70 with 20 inch barrel. I used Sierra GK 225 gr SPBT at 2350 fps using IMR 3031. Lethal on big red deer. John Barness has published some good loads with TAC. I think H322 is also a good powder for the 200 gr bullet. "When the wind stops....start rowing. When the wind starts, get the sail up quick." | |||

358 data abounds in reloading manuals. I can't imagine not being able to find a lot of it. SR4759 is about as dead on as one can get, in my opinion. I don't and never have owned a 358 but have two 9 X 57's and they are very, very similar. I use IMR-4064 the most and have had success with IMR-3031 also. DRSS: E. M. Reilley 500 BPE E.

When I first started looking at powders for the .358 Winchester, it became pretty clear that W748 was a very popular powder for use in this cartridge. I have found out why. While my rifle likes a variety of powders (typical of the .358, it seems), 748 is just a tiny bit better at producing great accuracy and consistent velocities in my rifle. While my load development is still a work in progress, I have settled on a slightly less than max load of 50 grains of W748 behind a Speer 220-grain Hot Core to hunt with this season. This gives me just a tad under 2400 fps and 3/4" accuracy out of the 19.5" barrel on my M-600 Remington. While I've only killed paper with it so far, reviews on the 220-grain Hot Core's performance on game at these lower velocities are excellent. | |||
