The gun run of '08 started my reloading career. To be fair I wanted to reload before then, but I just kept putting it off because of start up cost. I started in 2010 when components started to be normal again, thanks to my wife buying my press for my birthday (and in turn being mad that I had to spend another 200 bucks on dies, powder, primers, and projectiles).
I never dreamed of owning any kind of firearm in a more unique caliber. Heck, growing up in a small town where 30-06 is king, .243 winchester was considered exotic. Never mind 7mm-08. Now, I can buy about what I want. Oh, and I can shoot about as much .357 as I want. And I can make match grade rounds for about the price of bulk ammo. Shoot I could shoot 338 lapua for around 1 buck a round if i so desired (instead of 3 or 4). There are tons of reasons to reload. I can shoot more. I can buy guns in calibers that were cost prohibitive before. I enjoy my time at the reloading bench. The number 1 reason is putting rounds I loaded into 1/2moa at 500 yards.
