You'll save money by reloading, how much you save is up to how many bargains you find & how much sweat equality you put into reloading.
Look at reloading equipment as an investment rather than an expense. I started reloading in the mid 80's and slowly collected/expanded my equipment to fit my reloading needs. I've used this equipment for years an can easily sell it for a lot more than I have invested in it. There are not a lot of hobbies out there that you can say you have used an item for 20+ years and can easily triple your money by selling those items now.
If you're going to reload pistol ammo get into casting also. Lead is free so the bullets you'll be shooting are free or next to it. I get all my lead for free & make my own lube & end up with a cost of ½ cent per bullet for the lube/electric/propane that is used to make them.
Powder valley just had a deal on shipping if you bought over 10,000 primers. They'd pay the shipping/ins/hazmat fees & you could also ship up to 40# of other merchandise with the primers. If you just ordered 8# of a middle of the road powder like universal clays for $114 you could load 10,000 medium duty 357's with the primers (Tula @ $200for 10,000) for a total of $314 for 10,000 rounds of ammo.
Add the cost of $50 to cast/lube 10,000 bullets; I'd have $364 in 10,000 357's. The other nice thing besides the price is that the reloads will be tailor made for accuracy/power in my pistol. What you save in reloading ammo will easily pay for the cost of the equipment.
I don't shoot that many 38/357's anymore, here's what I shoot every year anymore. There's 2500 38/38p+ loads on the left with rn & steal challenge bullets. The 1200 357's on the right consist of the same rn & steal challenge bullets. There are 500 empty 357 cases in the coffee can that still need reloaded. That's my 586 that I bought new in 1987 & have beat on the pistol mercilessly shooting well over 100,000 38/357's with it. I sent it back to S&W in 2008 to get rebuilt & I'm back in business.
