Note: This thread was originally posted by me December 2011 and lost in the Great Fiasco. I now present it again in its entirety.

So I just reloaded all my loose 7.5x55 Swiss brass. Let's start from the beginning.

Here's my bench, made from 2x6 cutoffs and a couple of 2x4's. 30"tall x 4' long x 2' wide, screwed together, glued, reinforced and sealed with a couple of coats of polyurethane.

Nevermind the RCBS Lubesizer on the end. It's for sizing and lubing cast lead bullets, which we aren't going to cover in any detail here. Casting is a while 'nother can of worms.

TOOLS YOU NEED FOR RELOADING:
>Lee Challenger Breech Lock Single Stage Press Anniversary Kit
About $90. Comes with press, powder measure, powder scale, priming arms and primer holders, case lube, plus a slew of small infrequently used tools.
>Your choice of dies
$30-$80. Lee makes cheap good quality dies, but in the case of 7.5 Swiss, they size the brass to the GP11 ammo dimensions, rather than to the size of K31 chambers which is larger and accounts for case expansion. My Redding dies came highly recommended. Lee dies work great for .357 Mag.
>Powder, bullets and primers
Powder has a median price of $25/lb in small containers, but pistol powder and bulk powder and MUCH cheaper. There's also pulldown and foreign mfg powders for those looking for super-economy.
$30-$40/1000. Primers pretty much have to bought new. There are Small Pistol, Small Rifle, Large Pistol, Large Rifle, #209 and magnum versions of all. Large pistol and rifle are the same size, but the rifle primers are harder and thicker to account for the increased chamber pressures. #209's are used for shotshells.
Bullets are all up to you. I haven't reloaded a single jacketed bullet yet. Every one of them has been a homemade cast lead boolit. Even buying cast lead is a minor fraction of the price of new jacketed.

As you can see, getting started is not expensive at all.

I clean my brass in a cheap Harbor Freight tumbler using polish-treated walnut shell media.

The trick with the cheap Harbor Freight tumbler is to adjust the motor to tighten the belt as soon as you get it. The most common complaint is broken belts, but I've run mine on the original belt for over 200 hours now.

You don't need a case lube pad ($4 used) but it comes in handy. Case lube is water-based. Oil-based lubes do not have the correct properties for this, and using WD-40 will only get a case stuck in the dies that has to be removed at the factory, if ever. A tube of case lube ships with the Lee kit and is a year-or-longer supply.

I only reload .357 Mag and 7.5 Swiss for the moment, so my powder selection is limited.
When reloading, especially with cast, chamber pressure is the most important consideration. Without a minimum pressure, the case will fail to seal the chamber and you'll get gas blow-back through the action. Too high and gun goes kaboom. Pistol powders burn fastest, followed by magnum pistols, then small rifle powders, then magnum rifle powders. In fact, the powder used in .50 BMG burns so slow that it's known to often fail to ignite in smaller cases with standard primers.

Unique is an all-purpose fast burning pistol powder that's useful for reduced loads in magnum handgun cartridges and rifles.
2400 is slower, and useful for magnum handgun loads as well as reduced power rifle loads.
H110 is specifically for .357 and .44 maximum loads. It's also so damned fine that it leaks from the Lee powder measure. NEVER USE H110 FOR REDUCED LOADS.
H4895 is a mid-range range rifle powder. A 4895 analog is what the Russians used for 7.62x54 and what most .30-06's, .308's and similar cartridges are loaded with.

A full powder burn rate chart can be found here: http://www.hodgdon.com/burn-rate.html

The faster a powder burns, the less it takes to hit a certain chamber pressure. While I can shoot 20 grains of 2400 all day long, 20 grains of Unique would kaboom.

Right now I'm using H4895. It's an extruded stick-type powder with a green-gold color. I'm trying to work up a high velocity cast load.

The Lee powder measure is a volumetric measure that is adjusted by unscrewing the black plastic plug in the aluminum pipe. It's graduated in 1/100cc if you have a density chart, but trial-and-error is just as easy.

Drop a load, weigh it out and adjust the plug as necessary to get to your goal. In this case, I want to try 36 grains of H4895, which should give me an estimated velocity of 2300 fps. Not quite full power, but getting close. To go any faster without losing accuracy requires an even slower-burning powder. I can't be certain of velocity without a good chronograph, but that's an educated guess based on known .308 Win and .30-06 data.

There are several powder styles around.
Unique is a flake powder with a large surface area compared to mass.

One more thought on powder:

A double charge is a very real danger when reloading reduced power loads. If I were putting my usual 15 grains of Unique or 16 grains of 2400, an accidental double charge would mean a bolt flying back into my eye. With 36 grains of H4895, a double charge would overflow the case, so visual inspection is sufficient. With the faster powders, I take a tire pressure gauge, pull the stem out, and run it down into every case looking for a double charge. Vigilance is key when trying to save money.

The bullets I'm using today are from a custom mold I had made specifically for K31's. 180gr flat nose, with the nose tapering to be a bore rider in the front, an extra-large lube groove and then gas checked in the back. A gas check is a copper cup that crimps onto the base of the bullet and grips the rifling better than the softer lead alloy. Without a gas check, lead bullets are only good to about 1600 FPS. With one, they can be successfully fired to around 3200 FPS. When using too small or too soft of a bullet, the bullet gets forced down the barrel faster than it can spin, stripping off the out layer and leaving flakes of lead lodged in the grooves between the lands. Too hard of an alloy will fail to seal the barrel, causing the gas to leak around it and cut divots.

The reason I wanted a bore rider bullet is that K31's are notoriously "difficult" (compared to everything else) to reload for with cast because it has such a short throat. These chamber and shoot like a dream, though, unlike the two other bullet molds I've tried.

Feel free to ask any questions at all about the physics, process or anything with reloading. I've put over a hundred hours of study time in before even buying a press. YOU don't have to, just for reloading, but casting bullets is an art unto itself.

Great posts would you mind detailing the process one might go through to determine the proper powder to use for a particular cartridge?

you need to consider burn rate, energy density and load density, costs and availability. you won't get insight into most of those without trying or quickloading, so the easiest way is to search for recommendations of experienced loaders.

you can reload berdan primed cases. there are several approaches from simply priming with berdan primers again to converting the case to boxers. you'll figure out the most practical solution when it's time.
