I started reloading in 1962. I needed to so I could shoot(mostly ground squirrels and birds) with the little money I had.
Fast forward to now----I have a Dillon650, 2 RCBS RC,s(one is a spare), a RCBS Jr(for seating bullets and some complete loading of certain pistol rounds) and a Hornady single stage set up for 50bmg. They all are in one room(daughters old bedroom) along with other equipment and supplies. In another room is storage for ammo, more powder/primers/targets/mags/clips(yes they are different), shooting bags with stapler/tape/earmuffs and such for the range, and some equipment. It also has 3 large safes that are full of firearms. Fully 1/3 of my garage is supplies/brass/bullets/ammo/chrono/target holders/portable shooting benches. My pick-up always has bags(for resting firearms on), 5qt ice cream containers for brass I pick up, brass picker-upper, towels and a adjustable rest from Hornady.
At present I load for-204R, 223(rifle and pistol), 257R(rifle and pistol), 25-06, 257W, 308win(rifle and pistol), 30-06, 300win mag,264win mag, 7mmrem mag, 338win mag, 7-08, 6.5X55,30-40Krag, 303brit, 6.5jap, 7.7jap, 7.62X39, 7.62x54R, 8mm mauser, 50bmg, 7.5swiss, 30Carbine & 45-70. I might have missed on. For pistols only I load 38sp, 357mag,45ACP, 5.7X28(a real pain), 9mm Luger, 9mm MAK, 44mag, 454Carull, 500S&W, 7.62X25TOK and maybe an odd one I missed.
When I started loading the only way to get a Nosler Partition in your ammo was to load it yourself. There was little if any other upper grade bullets even being made. DO NOT LET ANYONE TELL YOU THAT YOU WILL SAVE MONEY RELOADING! You will not. If you add up what you spend at the end of the year you will find you spent as much or more than if you just bought ammo. The DIFFERENCE IS YOU WILL SHOOT MUCH MORE AND/OR SHOOT CARTRIDGES THAT IF YOU HAD TO BUY FACTORY AMMO YOU WOULD NOT OWN. You will also be able to tailor loads for each firearm and the purpose you are going to use it for.
I sometimes can by factory ammo cheaper than the hunting ammo I make. But I know that I carefully made my ammo for a certain rifle/pistol using a certain bullet selected for the game and where I am hunting. Just another part of the hunt for me.
Factor in it is a great hobby and most will enjoy the reloading.
