I shoot prairie dogs and I go through a LOT of ammo - 17 Mach IV, 17 Remington, 223 Remington and 22-250 Remington. We go up for a week about every month between say May through October. So buying that much commercial ammo is expensive. Also by now I have my cartridges setup "just right" for each rifle; primer, case, bullet, powder, COL - etc. So for me reloading is the only way to go. I also shoot CAS, 38 Special, 44-40 and 45 Colt. There is what our club calls "Practical Pistol" and two and three gun matches so throw in 9mm and 300 Blackout. Now deer hunting I us a TC Contender in either 7-30 Waters or a 357 Max, try to find ammo for those and a 6mm Remington rifle (limited on what is available). The 30-30 and 30-06 went to the grandson a while back, but I still load for him. I also shoot a 40-65 WCF in a Sharps and a Rolling Block.
So between my odd ball stuff and my high volume shooting, reloading is a must. Now granted I'm an ROF (Retired Old Fart) and still in good health, the reloading is a way to pass the cold Nebraska winter.
In my Rifle and Pistol Club we do a lot of "trading around". I just picked up 500 pieces of one fired Norma 22-250 for $25.00. We also had a club member pass and his wife donated all his reloading stuff to the club. He had primers and powder up the ying-yang, which makes it a lot cheaper than you can think How about $10 for a brick of primers or $100 for a 8# keg of powder. I do always look out for sales.
Yes I have a lot of $ tied up in equipment and supplies, don't tell my wife (LOL), but that will make my nephews and grandson happy when I go to that big shooting range in the sky.
