i just picked a up a custom .358 Norma mag built off of a 1903 Springfield, and am looking for some good loads, that are safe in this older action. will probably use 225's most of the time, gun store work at had the discontiuned nosler 225 bt's on clearance for $16a box, so i cleaned them out  270 win, it's the cartridge that makes me punch infants!!! | ||

Assuming you have a "high number" Springfield which did not have the heat treating problem of some "low number" Springfields, it is as strong as any modern turnbolt, and much stronger than the failure point of the cartridge brass. Any load that the brass tolerates for multiple reloadings is safe in your Springfield. The .358 Norma is a sleeper cartridge that didn't get the attention it deserved, probably because of the slim selection .35 caliber bullets for many years. That has changed now, and there are a number of good .35's available. The case is virtually identical to the .338 Winchester case. If you don't have readily available loading data, use .338 data for the same weight bullet as a starting point and work up from there. The larger bore of the .358 will produce lower pressures with the same charge as the .338, therefore interpolation of data in this manner is a dependable way to start. | |||

Excellent post!!! You should find reloading data for the .358 Norma anywhere data is published.....it's well documented! The Hornady manual also has data. It's an enormously powerful cartridge that I wouldn't hesitate to use to kill cape buffalo (assuming the right bullet) and it was legal where I was hunting.....possibly one of the best choices for big bears, moose, Eland, .....but like the .375 H&H, it's a lot more power than often required. /////////////////////////////////////////////////////////////////////////// "Socialism is a philosophy of failure, the creed of ignorance, and the gospel of envy, its inherent virtue is the equal sharing of misery."

i know the action is a Rock Island, not sure of the numbers, but was built by one of the best custom smiths in Canada, and used for years, so i'll assume it's a good one. this is gonna be my elk and moose rifle, might even try downloading it with the speer 180 fp's intended for the 35 rem, and use it on deer. i'll put up a picture when i have more time, it's a beaut! 270 win, it's the cartridge that makes me punch infants!!! | |||

Some of the Springfield fans here on AR can give you the serial number that's considered the changeover from "low" to "high" numbers. Not all low number receivers are a problem, but my understanding is that they were heat treated by hand, depending on the experience of the individual workman to determine just how much to give them. The outcome was overtreatment on some, resulting in very hard but brittle receivers. So, if it is above the "magic" number, not to worry. If it is below that number, then it might be wise to have the receiver hardness tested. My understanding is that knowledgable metalsmiths can re-heat treat the receiver, but I'm now trying to tell you a lot more than I know. It should make you a great elk and moose gun. I would use the same 225 BTip for deer. It will shoot flatter and its terminal performance will be just fine, even on the lighter stuff. | |||

Kevin I have usually used the 250 gr bullets in my old 358 with a near max charge of IMR 4350.The lighter bullets would not hold together. You may want to try 4320 or 4895 with the 225 partitions | |||

Kevin 303: This is a timely post for me as well. I just found a Husqvarna 1651 in .358 Norma, and am trying to figure out how I want to load for it. If they will shoot well in my rifle, I am thinking of the 225-grain Barnes TSX or the 225-grain Nosler partition. Dave One morning I shot an elephant in my pajamas.
