A couple of questions that will point you in the right direction in regards to deciding whether or not to get into reloading are:
1. Do you have the disposable income available to invest in reloading equipment? After all is paid for and brought home, this can be in the $1,000 range. If you settle for a simple and inexpensive (note: didn't say "cheap") reloading press, you may find yourself wishing you got that fancy-shmancy progressive when you had the money. That being said, I still use a simple but reliable RCBS single-stage press that I bought many many years ago...does the job, not as quickly as a progressive, but it does the job.
2. Do you have the time to dedicate to the reloading processes? This involves case preparation (cleaning, polishing, measuring and trimming, etc), as well as actually cranking the ammo out. Several hours each weekend, or a weekend every month or so.
3. Will you be reloading for more than one caliber? Some reloading presses are only good for pistol ammo, so if you end up getting one of these, forget reloading rifle ammo. BUT, as a general rule, if you reload more than one pistol caliber, it becomes worth the investment right away.
4. Do you understand that reloading does not make the ammunition free? It only makes it more affordable since you are not paying yourself for the labor, so you only buy components (example: 1 lb of gunpowder contains 7,000 grains of powder, at 6.0 grains per load, that one pound can load over 1,100 rounds, and costs only about $29; .45 plated RN bullets cost about $37 for a box of 500; a box of primers (Winchester Large Pistol) costs about $40 for 1,000, so not counting cases and labor you are looking at $143 to reload 1,000 bullets).
If the answer to all questions is YES, then you can begin now to convince yourself to get into reloading.
It is a fun hobby to get into as a support hobby to shooting, and nothing will delight you more than having several thousands of rounds put away in your garage when ammo becomes scarce on the shelves at stores, or going shooting with buddies and when they run out of their store-bought ammo you still have thousands of rounds in ammo cans in the back of your truck! Whooo-hoooo! The look of envy is priceless!
Of course, being a buddy, you'll probably give them a couple hundred rounds each to "tide them over" (and maybe accept their cash donations), and then make everyone pick up brass for you!
You will at first rely on other reloaders' advice, but once you start, you will develop your own flavor of the reloading process. I know the method I use will not work for others, but it is how I choose to do it. So ask all the questions you can think of, and any others along the way, before you spend that first dollar!
