everyone tells you you'll save money as a reloader.
let me be the first to say thats a big ole negative. you wont save a dime.
however you'll shoot a whole lot more for the $ you have to invest into trigger time than you did with factory ammo, and end up with ammo thats accuracy tailored for YOUR firearm. and more trigger time = you become a better shooter.
if you shoot any volume, between the 3 of you, you can "pay" for a reloading setup pretty quickly with your cost per round "savings". and then since you saved so much $ you can even look at upgrading to a powder dispenser like a Chargemaster. Or a wet tumbler. or.... or....
the real trick is to get on the 'buy a box a week program" but instead of buying a box of 20 rounds of ammo... its 100 bullets this week. and 1k brick of primers next week. and a pound of powder the week following. and then another box of bullets, and then more powder, etc.
Since it sounds like you'll be reloading for a couple shooters - an even better option will be to pool your $ and buy powders in bulk (get 8lb kegs), likewise for the primers (1k bricks minimum). Bullets where possible. Watch for powder/primer sales w/ free hazmat and then be ready to pounce. Have $ set aside for when blems show up and buy a couple thousand blem/2nd bullets for practice - and save your premium quality stuff for hunting season. Things like that.
next thing you know you'll have lots of components around, and never have to worry about finding your pet load on the shelf of the local bubba-mart when you need/want one.
and you wont feel bad about giving those 7mm-08's some extra trigger time through the year at the target range.
personally going to the range with less than 200 rounds with me seems like a sacrilege now.
just for reference on how much reloading you get out of a pound of powder per caliber - this is just rough numbers, but a nice benchmark anyway (different powders, different bullet weights,etc).
This will be helpful when figuring out a balance of components to purchase to make complete ammo.
223 - 275 rounds
308 - 165 rounds
7mm-08 - 165 rounds
9mm - >1000 rounds
450 bushmaster - 180
