Reloading kept me out of trouble and thereby helped my Marriage. Who knows what trouble I may have gotten into down at the beer joint instead of being in the reloading room downstairs?
Reloading is seriously interesting. Especially when combined with a casting setup and a chronograph. If one were to add even a single boolit to homecast (HA!) then boom, the bottom drops out of the (usually) most expensive part of reloading and boolits start costing 2 cents apiece or less, instead of 10 or 15 cents apiece that store-boughts cost.
Home-casting brings the cost of most popular (small cased) rounds down to below the cost of decent 22 LR's. For example, I can load 100 38/44 Specials for about 4 dollars. The 357/44 Mags about a dollar more for powder overall. A box of 100 CCI Mini-Mags cost 6.99.
Even if I got crippled up or whatever and couldn't go shooting anymore, I would want to continue to reload because it is just so darn interesting that it's a hobby unto itself.
