I got into it mainly for cost savings. .45acp is the only caliber that I reload. Cheap stuff can run $170 per 1K. My cost for 1K rnds is $105 using range brass. Most factory ammo that I've seen averages out to $200 per 1K.
The other claibers that I shoot, .22lr, 223, 7.62x39, 7.62x54R, and soon 9mm are too cheap to justify reloading.
I do want to get into a .38special setup for the dillon.
