I am just now tooling up to reload metalic cartridges; however I do reload approx. 15000 to 18000 shotgun shells a year as I compete in registered skeet. Mondays are typically my reloading days as no ranges in my area are open. I have loaded as many as 1000 in a day and that makes for a long day. I don't mind reloading, most times I find it rather theraputic, off in my own little world.
There are several advantages in reloading. Many reload simply for cost savings which is a definite advantage. Others load for accuracy. I have finally gotten to the point that if I have a rifle that won't shoot half minued accuracy, I don't want it. I currently have two builds in progress, one should be finished any time now and the other should be done sometime around June. (fingers crossed) I want to squeeze every ounce of accuracy out of these rifles that I'm capable of. I know that there will be a rather steep learning curve but I'm looking forward to process as well as the outcome. The simple fact is that, by reloading your own ammunition you can create premium ammunition at a fraction of the cost of factory ammunition.
Probably a bit more than you wanted but I do kind of enjoy it.
