10mm magnum dies

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!

So to be clear. Are you implying I shouldnt shoot 10mm Mag factory loads after having my S&W 610 reamed to accept 10mm Magnum?
My plan is to dissect 10mm Magnum rounds to get a base for reloading them.
And there is some info out there for the 10mm Mag.
 
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.

This doesn't sound like a good idea if you are trying to use this for load data. Are they factory loaded? Are these reloads where you know the exact powder and bullet type? I would follow a recipe instead of trying to back-end into something. Each power type is unique and what you may think is a FMJ bullet could be a thinly copper plated projectile, which will likely be loaded as if it is a non-jacketed lead bullet.

They're made by Double Tap.
From what I've been able to ascertain the numbers and powder type are available but in short supply since not many are out there in regards to the 10mm Mag.
There are plenty of burn rate charts available out there for pistol powders.
I plan on hitting double tap up for some info.
We'll see if they respond.

Oh...I'm not just going to go willy nilly loading rounds.
There will be much research before hand.

Interesting. I always thought those boutique ammo shops used a proprietary powder blend to get the exact burn rate they want. If they gave away their recipes, why would anyone buy their ammo? Having said that, the shooting community is often a very helpful bunch so nothing would surprise me. Keep us in the loop as to how they respond.

Good for you for getting into reloading and seeking advice from the experts (and non-experts like me.) It's a lot of fun and very satisfying.
 
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.
Excellent! I started running automatic screw machines in '65. I took Metal Shop for the last 4 years of high school and was a teacher's aid the last year. I worked as a machine operator/machinist (small runs of parts for various used including aircraft. ). I also taught/trained apprentices in Auto/Heavy Equipment Electronics. I stick to my original thoughts; It is much easier and "longer lasting" to start learning on a basic portion of the subject. I started the training with how a lead/acid battery works. The apprentice may have done "OK" if I started with digital, fly by wire safety systems on 27 ton cranes, but that's doubtful. It is much easier and much more informative/enduring to start learning reloading with a single stage press than learning to operate a reloading machine...

I dont see me having a problem with a progressive loader.
Setting it up wont be an issue.
You simply take it one station at a time.
Same as setting up a Warner and Swasey or a CNC that has a 50 tool carousel or more.
This is something I'm very familiar with as an operator and programer.
 
Nothing says you have to use a RL550 as a progressive, it works just fine as a single stage if you want to.

As for 10mm mag data, I started with the HI end of 10mm and the Low end of 41 mag and adjusted as needed, Blue Dot, 800X, wc820 all had potential.

Do you have the data?
And you're talking about the 10mm mag cartridge and not an overcharged 10mm?

Ended up with the RL550C with all the extras..final cost on the press was $851.92.
Picked up dies for .380ACP,.45ACP,and three sets of the 10mm so I can preset em and forget em for the .40 and the 10mm. Mag.
And of course a set of 5.56. I'll probably ad .270 and 30.06 at some point when we buy our new property. Also picked up 6 tool heads.

And of course all the basics I'll need to get started.
Case Lube,CV2001 case cleaner,case trimmer,powder scale and of course a reloading manual.
Already have a crapload of calipers from my machining days.

Grand total of $2653.

Of course now I'll need to find the elusive primers,powders,cases and bullets.

Congrats on your new equipment! Sounds absolutely Top Shelf!

Best of Luck!

P.S. Yes, you will...
