Reloading 10mm

[Ugly Dwarf]

Ahh... the spacer goes between the lock ring of the die and the press. I was envisioning something that went between the shell plate and the die... and that would be problematic with a progressive press.

You still need remove the die each time you change, but (assuming you use RCBS style lock rings with a set screw) you can screw the die back in with good repeatability.

Very interesting. I will keep these in mind if I start reloading .40S&W.

I noted the RCBS manual linked only lists these for .357 Mag/.38 Special and .44 Mag/Special. Perhaps it's dated and they need to update the list to include 10mm/.40S&W. If / when the time comes, I'm sure a quick call to RCBS will get me the appropriate part number.

Yeah, you've got the idea. They work pretty good. In addition to the issues you've listed, I've noticed that when I use them (for .38/.357), they only really work as advertised if you're using the same projectile, and if you want to maintain a similar seating depth. If you switch projectiles, seating depth and OAL are going to change...

So, if you do end up getting a spacer, make sure you buy bullets that are decent projectiles for both .40 and 10mm loads. Otherwise, you're going to have to recalibrate the die anyway...

Is it just me, or is the RCBS website one of the worst websites on earth?

I can't find anything easily on there! It's all just links to PDFs that aren't really searchable because they're set up in "image" format. I wish they'd re-vamp their site...

You should just forgo the 10mm auto and get the 610 and have it converted to 10mm magnum. I just purchased 500 pieces of starline brass in 10mm magnum and am sending my cylinder out soon for the conversion (about 120 dollars). I should be able to get the 180's up to 1600 fps with the 6 inch barrel. I will be close to 44 mag territory.

Reloading for 10mm is the only way to go. Glock talk has a forum specifically dedicated to reloading the 10mm. Order some Starline brass, wait a few months for it to come in and rock out.

Wow! That is sweet! This is perfect since I don't have a revolver yet.. any other revolvers that shoot both 10mm/40SW?

Ruger Made a black hawk called the "BUCKEYE" It has 2 cylenders 38/40, and 10mm/40 sw It has been discontuned ,but they do show up from time to time,on gun broker. I am not sure if it is legal to ship it here though.

As for expencive ... 13.6 cents for a new starline brass, 3.5 for a primer. A few cents for some blue dot. Maybee 1cent for the bullet I make. If you find your brass ,you are shooting for less then .08 the 2nd time.
