358 win mag

I'm anticipating 2700 fps with 200gr TTSX
This calibre isn't very popular these days with very few factory rifels chambered in this calibre
However, it's fun to own and shoot, simply necking up 308 brass for approx. 3500 lbs muzzle energy
 
You are talking about .358 Win... NOT WIN Mag... the .358 Win is a necked up .308 case... 2600 with a 200 would be hot... you won't get 2700... IME.

yes, 2700 will be attaianable, but I'm afraid for the primer pockets being enlarged and no good for reloading.
Even though I wasnt getting stiff bolt lift, deeply cratered primers, or even shiny cases at the bottom....at 2600, my primer pockets were enlarged and discarded. That was with TAC POWDER and using Lapua 260 brass. I'll be using 308 brass next go-around. AND, yeah its 358WIN for the readers sake.
I GOTTA go make some money

The fact that you are developing obviously excessive pressure at 2600fps , should tell you that 2700fps isn't likely going to be obtainable with reasonable pressures.f:P:

Here is the reply from a Ramshot Tech, when asked for a load to use in a Ruger 77 in 358win.

We suggest the following.
Caliber: .358 Winchester.
Barrel length: 24”
Powder: Ramshot – X-Terminator®. (1st Choice)
Bullet weight: 225 grains.
Start load: 41.0 grains (ca 2100 Fps)
Maximum load: 44.5 grains (ca 2400 Fps).

Powder: Ramshot – TAC®.
Bullet weight: 225 grains.
Start load: 41.4 grains (ca 2050 Fps)
Maximum load: 46.0 grains (ca 2400 Fps) LD ca 106%.
NOTES:
It’ important to note that SAFETY is our prime concern therefore we strongly recommend.
1. ALWAYS BEGIN LOADING AT THE RECOMMENDED MINIMUM “START” LOAD and develop loads in 2% increments towards the MAXIMUM load.
2. If possible, measure the velocity and correlate with our data.

You are enlarging primer pockets after a single shot with brass designed for 60,000psi so you are probably a good amount above that already. Most high pressure brass can handle 65,000psi or so (270 Win levels) before things get bad and enlarged primer pockets after one shot is considered bad. You might be at 70,000psi or something. The rifle itself would have been proof tested above the 358 Win max pressure of 52,000cup so you are probably proof testing the rifle every shot currently. That generally isn't regarded as too safe or good for the rifle.

Yes, it can do 2700fps, it can probably do 2800fps, maybe 2900fps, but not at pressures meant to be used in the rifle or cartridge. Something will fail catastrophically eventually as your brass is already failing not-catastrophically.

The fact that you couldn't even get the name of the cartridge correct, quite an important thing when trying to communicate with others, leads me to question your experience level as well.
 
We can only hope that he does his shooting alone so that he doesn't endanger anyone else, as he attempts to live up to his username.

Lol...

Meetyourmaker... having repeatedly called the cartridge a .358 "Win Mag", I have to believe that you have very little experience... I wouldn't be surprised if your subsequent load post was a "cut & paste" from some other website. I got my M77's to 2700 with compressed Varget and 200 SP's and was forced to back off due to pressure signs... I load my 77's to 2625 and my BLR'S to 2500... with strong cases and easy action movement... if you want more than what the cartridge offers then go with a different cartridge, the .35 Whelen and .350 RM will both give you what you are looking for.

:agree:
 
You aren't being bullied, you're being given advice that what you're doing isn't safe. Sure, it isn't worded in the most polite way but that's because most people have seen posts like yours over and over again and are just getting tired of answering them. You can keep doing what you're doing, everyone so far as advised against it in one way or another. If you insist on pushing the round way past the rated pressure, your rifle might not explode and kill you, modern rifles are designed to not do this, but eventually something may fail catastrophically.

People can't provide information such as load data, unless they know what cartridge you are referring to, and you kept referring to the 358win mag, which doesn't even exist. Then you go on to tell everyone that to reach 2600fps, the primer pockets of your Lapua brass are so badly enlarged that you had to scrap the brass, yet you are talking about reaching 2700fps. In order to expand those primer pockets enough to require scrapping after one firing, you are likely producing at least 75,000 to 80,000psi. And yet you want to gain another 100fps. You aren't being bullied, you are being given advice that could prevent you, or someone else from being injured due to you apparently not realizing just how dangerous it could be to keep increasing the powder charge in an attempt to reach 2700fps.

When you attach sarcasim to supposedly helpful information - well, it just doesn't resinate with the crowd and belittles your intelligence on the subject.

The information in your posts makes your lack of knowledge on the subject very evident, to the point that I doubt that anyone is taking your posts very seriously.
 
I have a Savage 99 in 358 win . with 100 new brass and lots of leads to load up
I'm loading 200 grain Hornady Interlock SP with 46.0 grains of IMR 4895

Sarcasm - definition; A form of irony in which apparent praise conceals another, scornful meaning. For example, a sarcastic remark directed at a person who consistently arrives fifteen minutes late for appointments might be, “Oh, you've arrived exactly on time!”

Ergo... I was not using sarcasm... I was being direct... and you are asking for assistance, then disregarding the informed advice offered and answering your own question with information contested by other (more) experienced handloaders...

If you don't want an answer or already have the answer you are satisfied with, then don't ask the question.

JMO... good luck.

Calm down, Friend. These rats are just trying to save your bacon....and that of anyone near you when you are shooting your handloads.

You should stop talking and heed the offered valuable information and experience that have been forwarded to you here by folks who actually know what they are talking about. If you think the response contains sarcasm it because you are arguing with the very people you came here to for advise.

Listen and learn young grasshopper. Your attitude won't get you far here or anywhere else for that matter.
