I have no doubt reloading saves money and you will always have ammo by doing so. That is assuming you keep up with your supplies. I started reloading because I needed obsolete ammunition. I have Wincheter 1886 lever guns in 40-82, 50-110, and 45-70. The ammo was going for $60-$80 a box of 20 for the 40-82 and th 50-110. Then I started reloading 300 Remington Ultra Magnum. Try finding a good price on that caliber. In addition to what I have listed above, I now reload 375 Cheytac, .45ACP, 45LC, 44 magnum, .270Win, 32-20, 5.56 and .308.
You have to buy everything in bulk. I always buy brass in lots of 1000. Buy bullets in bulk as well. If you are one of those that buy small lots, you will always lose. Always buy powder in 5-pound or larger containers. Understand that depending on how hot you load your ammo, will depend on how many times you can reuse the brass. That is where you SAVE THE MOSTon your ammo. Be frugal. I went to an M1911 operators course a few months ago. I told the range guy I wanted to pickup my brass. He said I could have it all from everyone if I wanted it. We shot for 2 days. I brought 2-home depot buckets and walked away with about 13 thousand pieces .45 ACP brass. I don't see me buying any for years if ever. That is how you have to look at reloading. I bought 2000 Sierra 175 gr for my .308 a few months ago. I am glad I did as everyone knows how hard that specific ammo is to come by these days. I always have ammo. To me, that is what matters.
I agree with the other posts that state you should buy top of the line equipment. You want reloading to be easy and produce so you will be inclined to do the job. I started with a Lee Progressive 4-stage reloader and now have 3 different presses. I have a Dillon XL650 for most of the calibers and a Redding Big Boss II for the .375 Cheytac. I still use the Lee Progressive 4 stage for my obsolete Winchester loads. More time consuming but that is the nature of reloading that type of ammunition.
