Home Forums Hunting & Shooting Ask The Gunwriters Short 30 caliber belted magnum ?

.

The Dillon Precision Super 1050 progressive machine will handle 30-06 length cartridges, but nothing any longer than that.

The original 300 Winchester Magnum has a brass length and overall cartridge length longer than the 30-06, so it won't work in the Super 1050 press.

Was thinking of using the 308 Norma Magnum, but it too is longer than the 30-06.

Assume the 30-338 Winchester Magnum wildcat will fill the bill as matching the 30-06 brass and loaded cartridge length.

Any other recommendations for a 30 caliber short belted magnum ?

.

Why does it need to be belted?

.

Well, for one, I'm from the "belted generation".

Second, I've got lots of new belted brass cases, and having brass in these days of shortages has some merit.

.

Not a Gunwriter and it may be a stupid question, but shouldn't the limiting factor be the length of the cartridge rather than the case? Pretty sure the .300 WM is the same as the -06.

Always thought a 30 Newton was a sexy caliber....but, I don't know if anyone would have brass, etc....nice round though.

Give the 308 Norma Mag. a try. It is a under rated cartridge and quite unusual. Plus when you are around snobs who don't like magnums you can always say you're hunting with a 308 Norma and very few will know it is a belted magnum !

How about a .30 Cal on the .350 Rem Mag case?

I don't believe you are correct. .300 Win Mag case length is longer than '06 case length but the overall cartridge lengths should be the same at 3.340". That was the whole point of the "original short mags" ... to fit them in an '06-length action instead of requiring an H&H length action.

From the 9th edition of the Hornady manual...


Cartridge ............ Max Brass ..... Max COL

30-06 ..................... 2.494 ........ 3.340
308 Norma Mag ....... 2.559 ........ 3.345
300 Win Mag ........... 2.620 ........ 3.340
338 Win Mag ........... 2.500 ........ 3.340
30/338 Win Mag ...... 2.500 .........3.340


The 30/338 Win Mag is not in the Hornady manual. I am just assuming that the wildcat 30-338 Win Mag will match the factory 338 Win Mag.

I do not know if the brass length is a deciding factor in the Super 1050 or if it is only the COL.

You'd be better off loading rifle on a Dillon 650. The 1050 brings nothing extra to the table and had a few shortcomings for loading rifle. OAL variance for one thing, and you cannot properly resized and load rifle on the same toolhead unless you are using a Lee Collet die. The cases have to be lubed, and then it needs to be removed before you lube.

Actually a Dillon 550 is likely a better choice.

.

You are right about the 650 being a great machine for rifle loading, as is the 550 too.

I have Dillon 550, 650, and 1050 machines and like them all.

Have gotten a shell plate for belted magnums for the Super 1050.

Cannot let it go to waste.

Getting some custom parts for the Dillons takes a little looking.

As a side note, the 650 is great for 375 H&H and for 460 Weatherby too.

.

There is some merit to a 30/350 Rem Mag cartridge.

I have a Montana action which was made for the 6.5 mm Rem Mag and 350 Rem Mag cartridges.

It could handle a 30/350 Rem Mag.

But not sure that it would not have much more oomp-ah than a 30-06.

.

Real magnums wear belts.

A .300/.350 Remington Ackley Improved would be very close to the .300 WSM.

Call Dillon, you'll have your answer in moments. I'd bet you can do a .300 Win Mag on a 1050.


(Of course I have been wrong before...)

308 Norma would be cool, and given the Dillon PROBLEM, you NEED a new rifle.

Good to hear from you Hammer, my 30-338 is a long throated and long barreled M70 PF. The guy that built it, did it around 1 bullet the 180 gr NBT a long while back before the current crop of wonder bullets. Cases are a 1 stroke deal with new 338 brass in a full length 308 Norma Mag die, I have the Wilson dies for it but no little arbor press. He cut the throat so those NBT's are seated out at 3.55" yeah they work and feed well in a 3.6" Win box sans any block. When seated at that length the base of the boattail is even with the neck/ shoulder juncture, no bullet encroachment on powder space. With a Dillion you'd have to slide the rd out of the seating station and seat it on a single stage to avoid your length problem. Like it? yeah I do, 3150 fps with the 180's and only have to neck size. 338 Win brass is 1/3 as expensive as Norma 308 brass when you can find it . my 30-338 is faster than either 300 Wins I have or the 03 custom 308 Norma mag because they all have 24" carbine barrels and the 30-338 has a full 30" tube, inexpensive extra velocity.Sorry, but I don't advocate deep seating bullets when you want performance because of short magazine length.Can't see taking 2 steps back for a small gain or none at all.

Thanks for the information on the 30-338 Win Mag.

Hammer your welcome, I don't have a newer Sierra manual but the older ones and the latest I have #5 has pretty good data on the 30-338. Trim to length is 2.490 and their test gun had a fairly std chamber not requiring more than a 3.3" seating depth for their bullet lineup. That might well give you what you want for OAL and Dillon reloading use. Good luck on your project. Magnum Man

That has been done. It is identical to the 30-06.
