10mm magnum dies

Texas S&W Shooter · Dec 21, 2020

Getting into reloading and I dont know squat.
I've decided on a Dillon,not sure which one just yet,and I'm looking at dies.
Obviously the common dies are easy enough to find. I plan on reloading 10mm,.45 ACP,5.56,and 10mm. Mag since I mainly shoot these rounds.
Cant find anything as far as dies go for the 10mm Mag.
Can you use the 10mm dies for the Mag rounds? I know you can use the 10mm dies for .40.
Any info would be greatly appreciated.

I'm pretty sure you can use your 10/40 dies for that I use my Lee set up for 10 and .40. With little adjustments, I don't see why you couldn't use it... im sure one of the reloading veterans will chime in here....

Is this round the 10mm magnum rimmed or is this a normal 10mm loaded to higher pressures.
The actual 10 mm magnum is a cartridge all by itself and does not use the same dies as the 40S&W/10mm.

Its a stretched out auto case, so a normal case....

Didn’t know there was such a thing. I gotta look that one up. I may need one.

SOFMatchstaff · Dec 22, 2020

You can use the 40 or the 10mm dies, I load the 10mm Mag for my Coonan. Its basically a rim less 41 mag or 401 power mag as far as power goes. 180gr JHP , a bunch of BlueDot and off you go...

About a Dillon press, I have had mine since 1984. It started life as a RL450 and later upgraded to a RL550b. Any version of this press is still under warranty!

You can buy "Caliber Conversions" that includes the powder funnel, shell plate, and locater buttons. The die sets are sold separately. Just like the dies will do multiple cartridges, so will the shell plates.

Call Dillon at 1-800-223-4570 and get on their mailing list for the Blue Press (free monthly catalog).

Pretty much their equipment is warranted against everything except loss! (Their brand of dies are made with features to make progressive loading even easier. All the companies are radiusing the mouths, but Dillon dies can be maintained without removing from the press!

I have loaded very close to half a million rounds on my press and IF I do my job right never ha a problem! NO news radio or TV or family distractions while loading, and you will turn out ammo of the highest quality!

Yah, what Ivan said! Double, on the distracted reloading! That's no radio, TV, cell phone, wife(and/or girl friend), etc. Distracted reloading can be worst than distracted driving! I, also have a 550 and I think it is better than the higher end "reloading plants"! More versatile and less to change when changing calibers.

FWIW, an aside, and just a question; "Don't know squat..." and you're starting with progressive press? Yep, it's possible to learn reloading on a progressive reloading machine, but there are easier, better ways...

I equate that to learning to drive in a Toyota with auto trans vs learning in a Peterbilt with 13 speed trans and a split rear end...

Interesting observation.

IF you are a person that has trouble following instructions, reloading is not safe for you on any machine! BUT if you pay attentions to details, and are not interrupted, the Dillon 550 series is as good of press as any to learn on! (It does not have auto indexing, so while you set up and/or learn, you control when the next step happens)

A tip: NEVER stop in the middle of reloading a case! You will have difficulty remembering which step you are on.

A tip: Only have the components you are using in the round being loaded on the bench! Also attach a note to your powder measure what powder and how much it is set for.

A WARNING: Reloading will only save you money if you shoot more ammo then the machine and components cost! Initial costs are One Time expenses, but there are continued expenses! There are a number of reasons Police Departments and the Military don't have their personnel reload their own ammo!

Believe it was one (or all?) of the Fabulous Furry Freak Bros. who 1st coined the concept... ?

I will paraphrase it for the purposes of this forum:

"RELOADING EQUIPMENT (& COMPONENTS) will serve you better in times of no money than money will serve you in times of no RELOADING EQUIPMENT (& COMPONENTS)."

Especially when it comes to PRIMERS!

Cheers!

P.S. You saw it here, 1st...

You’ve got a Coonan in 10mm Mag? Sweet! I’d love to see pictures of it. Who did your custom work?

It's the actual 10mm Magnum round.
Going to use it in my reamed S&W 610.

I'm a retired machinist so this should come naturally.
Always been good with mechanical mechanisms and have a natural ability to figure them out.
Plus I love to tinker.

I started out running a turret lathe at age 20 in 85.
It's pretty much a progressive reloader on steroids with 6 stations on the turret and 4 on the tool post.

The main reason I want to reload is for times like this where ammo is hard to come by and expensive.
Plus since retiring I have a ton of time on my hands.
And we're getting ready to purchase some retirement acreage so I'll be able to shoot in my backyard which of means increased shooting sessions....like daily.

I dont do pictures, but you wouldn't be able to tell any how. I did all the figuring and fitting, and got Dans' permission to order barrels from Storm Lake when they were making the 357 bbls a long time ago. that was the easy part, the magazine was a frankinmag welded together and fitted as the 10 metermiller case body is fatter than the 357 mag would accept. I got with the "Old Cur" , Dans Magazine Guru, and got some un finished mag bodies that I played with. It was a fun project and worked great with the 28 lb spring. I just wish the brass had been made with a small primer pocket instead of the large pistol it comes with... I couldnt convince Dan that it was(is) a viable addition to the Coonan line, sigh....

Re original question, I think I’d I’d focus on the known calibers for which there is much information available. Starting your reloading quest on a sorta “hot rod” load isn’t the best idea...and definitely not on a progressive press. Just my opinion. Are there any specs a available for this 10mm? Guidelines regarding pressures based on specific powders and bullet weights?

That being said, I’ d love to try it out! Sounds like a fun round.

Be careful.

Merry Christmas

No worries.
I have a bunch of 10mm Mag rounds already. It's a simple matter to disassemble one and weigh the powder and bullet.
And there is some limited info on reloading the round.

jcelect · Dec 23, 2020

Start with 10MM loads from the book. Increase your load in small increments, watching for high pressure signs. I have hot rodded the 10MM round for pins and exceeded the max load from the books using different powders to find the best. All loads were in a 610 6 1/2" w/180 gr 38-40 hard lead. The 38-40 bullets allowed me to use a strong revolver crimp and coated bullets reduced the leading, immensely!
