I've been casting intensively for almost forty years, so I guess I'm hooked.
In my view, casting is an expansion of my shooting hobby. I do NOT see time spent in casting (or handloading) as wasted in any way, nor as an inconvenience. Being of an experimental frame of mind, I enjoy exploring paths and techniques which are simply not available to a non-caster, and every mould that arrives in my shop is a new world of casting, loading, and shooting experience to be enjoyed. I reckon there must be around seventy moulds taking up shop space here by now, with more arriving every month or two.
Money is certainly not unlimited, and if I spend $15 on a box of jacketed bullets, then 100 rounds later all I have is an empty box. If I spend the same $15 on a Lee mould, then I have the capability of making THOUSANDS of bullets, for peanuts. With my wheelweight-alloy, 100 .44-250 SWCs cost me the grand total of about FORTY CENTS, and not only do I get the enjoyment of making them myself, but they are BETTER than what I can buy, and can be tailored to my needs in hardness, diameter, lubricant etc. This is very inexpensive, and very high-quality, shooting.
The dangers of casting, and the "dangers" of lead as a toxic substance, are exaggerated, just as many other substances are being grossly over-feared due to the EPA and misguided enviro-freaks. I also know many casters with decades of intensive experience, and NONE have indicated high personal lead levels in lab tests, including myself. Common sense and a careful approach are certainly indicated, but not fear.
Over many years, I have developed methods which allow production of over 400 GOOD bullets per hour from a single 2-cavity mould, and more than 1000 per hour from one four-cavity mould....without even working very hard. No unusual equipment is needed, just a normal mould and a good bottom-pour pot like my RCBS jobbie. I mention this to show that it doesn't have to take all that much time to make a sizeable number of bullets. My annual consumption must be in the order of 10,000 rounds or so, but I've never really tried to keep track.
Cast bullets are not necessarily the best for all purposes, but for almost all of MY uses these days, they are great. I'd be seriously bereaved if I lost the capability of casting my own. I've even been known to go to the range just to "make empties", so's I could stuff the cases again.....with cast bullets, naturally.
