I was doing extensive reloading up to about 10 years ago and really broke it down before I got into it in 1985
I found my nut, to where I was saving money was after the first 15k rds,,
I had started with a single stage press and it was ok, but too time consuming for what I was attempting to do so I kicked it up a bit.
I bought a RCBS 4x4, several caliber Dies, 45. 9. 38. 223, 30-06 and 303. at 15k I had saved enough to pay off my start up costs.
I was shooting an average of 2k rds a month in various calibers.
when 9mm and 38 got to 7 to8 bucks a box, I stopped loading those that was pretty close to my cost.
pistol caliber is fairly easy, basicly a clean, unsplit case, feed it, load it, store it.
rifle calibers have a bit more to pay attention to and if not seated and crimped properly the round is useless and dangerous. has to be properly lubed or will get stuck in your dies etc..if not properly seated and crimped you can have flash off in your muzzel/mag not a good thing either.
by the time I got good at it,(rifle ammo) 5.56 ammo got pretty cheap. I continued to load 30 cal until I sold those weapons, I no longer own a 30 cal rifle. so, sold the dies,
I am now back to a single stage press, I only load 44 spc for the most part as my cost is about 12.00 per 50 vs 19 for reloads and only shoot 1 or 200 rds a month.
I have 45 and 9mm dies if push came to shove I can load ammo. I still have about 1k in componets for those 2 calibers each.
with 45, 9, 38 and 556 being where it is price wise today..It is not cost effective to get into mass production to "save money" but still self satisfying that you accomplished something.
on the up side,
gave me something to do, out of the house, where Icould just lose myself for a few hours.
once you explain to the wife how dangerous it is if you confuse rounds, charges etc..she will leave you be if your reloading
My daughter would help often,she thought it was cool till she was about 15 and it gave us some daddy daughter time to talk, be together, was good for us. hell I got to do the "sex talk" with her when she was 12, while reloading...that was uncomfortable..but..mom couldnt handle it and thats why she was asking dad...
you can load hot or cold, make your own custom rounds,
the neighbors leave you alone lol..
I am a bit of an insomniac, so was not unusual for me to be up at 2am out in the garage reloading,,and those hours got some thing done rather than walking the floor and it did get me sleepy enough after an hour or two to go back to bed..
well thats my experience and input,,good luck with your decision either way.
