With that 357, if you're not a reloader, you still have the full range of power, from wadcutter 38 target loads, to full power 357 Ammo. And 327 and 32 S&W ammo is running twice the price of 38 and 357 ammo, on average.
It has been a LONG time since I have bought a box of ammo,and even longer since I bought reloading equipment,but I suspect you can set yourself up to reload 38 Special and 357 Magnum rounds for less than 4 boxes of factory ammo would cost you. The expensive component is the brass case,and you can use them over and over for a long time if you are careful with the loads and measure the cases for expansion.
I used to shoot a LOT of 45ACP loads,and generally speaking always kept a minimum of 500 loaded rounds ready to go,and another 500 or so in one stage or the other of the process of being reloaded. Even with reloading a number that high,I paid less than 100 bucks for the Lee Turret Press I used.
Reloading is simple. The only thing you really need to remember is do NOT get adventurous with your powder loads unless you are a a qualified gunsmith and completely understand the design and manufacturing of the weapon you are shooting to the point where you know you aren't taking any risks,and do NOT take specific load tips from people you don't know.
If you are even the tiniest bit anal,reloading and bench rest shooting ARE the sports made for you!
