358 Norma Magnum

[Baribal]

Well, Dave,

As you know, the .308 NM got an edge over the .300 WM prior the arrival of longer actions. With heavier bullets, the NM have very little to give over the WM... because of bullet seating depth and shank volume.
Also, with the .358 NM and 250 grainers, the velocity increase over the .338 WM is often a major difference.

Yes, I don't have an inkling of what the reference is to, and there's 20 inklings to a clue.

Sorry to confuse you Johnn... Here you go; small space, limited headroom, shire"ish" look = Hobbitt den (Lord of the Rings)... Bilbo is a hobbitt... a jest and nothing more... don't want you to burn-up any more inklings...

 

[Gatehouse]

Actually Johnn, if you put a magnet to those bullets you will find they are actually mild steel. Norma made a lot of those bullets in the past, as did RWS.

I have quite a few of them in several diameters for reloading.

Regards, Dave.

I had a box of them in .375 and while I never used them on game that I recall, shooting them into various mediums made me question their ability on big heavy bones. Seemed to expand pretty dramatically, often with core seperation. Of course, they were still 300 grains, so would probably tip over a moose.

That it is. Initially when I got my set-up arranged, with my 'needs' at the time it was more than adequate. With the numbers expansion in firearms and components over the years, the room has reached the point of saturation. It's like with my available gun safe space. A few years back, and just as a temporary measure, I bought an inexpensive Stack On, just to handle the overflow. Now, the overflow space is crammed full as well.
No, it's just that I'd never heard that term or expression before so it had me totally confused.

I have a rifle in this chambering - in fact it came from Whitehorse..........

........and I finally found some brass. But this brass had been cut to fit a .338 Win Mag. I am thinking I will re-size them, then shoot a fairly mild load in them, hoping the case will stretch somewhat. You guys that have loaded for this cartridge, any advice?

Doug

 

[Baribal]

A lot of people simply load and shoot reformed .338 WM.
You just have to back up a couple of grains.
When using .338 WM brass I do prefer to fireform them first, using about 10 gr of Bullseye or VV N310 topped up by slightly compressed COW.
Then it's just a matter of neck sizing and load.

Thanks much. I knew I could use .338 WM, but I load for fifty or so cartridges at any given time and HUGELY prefer to use correct headstamp where possible. So I got these Norma .358 NM brass, but they had been trimmed to .338 WM length. Any issues you can see for using them?

You & me both. Some items are a little difficult to find and about the only ones I fire form with an incorrect headstamp is using 30-30 brass to form into 219 DW.

 

[Baribal]

No, I don't see any possible issue from using them.

 

[Why not?]

Hi Doug!

I have used 338 Win Mag brass to make 358 NM for more than 40 years. One pass through the sizing die to neck it up, and you are ready to load.

Have never used anything other than full power loads, with the same bullet I hunt with, when firing for the first time. Actually forming the brass to 358 NM configuration takes very little pressure, so you get perfectly formed brass, the same velocity as with cases that are already formed, and there is little, if any, difference in accuracy.

Best,
Ted

PS: The fellow you bought the 358NM from passed away in his sleep last week. His celebration of life is this Saturday

Thanks Ted, these cases are .358 NM that had been trimmed and re-sized to .338 WM, so I guess I am good to go.

And thanks for the note about Ron. I was looking forward to meeting him this fall during the moose hunt at Keno City............
