I agree with Chaos on the cost of around $68/1000. From your price of $10/box, that's a savings of $132/1000.
Question becomes, how much do you shoot? If 500 rounds a week, savings is significant. If 500 rounds a year, not worthwhile.
I use a Lee turret press. You can buy from Midway for around $70 set up for one caliber. Add in some other things like a powder measure and scale, and you'll end up with aboutt $125 in equipment. This basically pays for itself the first 1000 rounds.
Using the turret press, I can load about 300 rounds an hour (with an auto powder measure attachment). I'll generally take a dreary Sunday or two in the winter and load enough to last me all summer. I do all my case prep in advance, so when I sit down to load, all I do is load.
I use basically the same load, a 200gp LSWC (usually from National Bullet in PA) over 5.7 grains of WW231. With a fairly heavy taper crimp will give around 900FPS, and is very accurate.
One more advantage to the Lee turret press, is that you can buy additional turrets for around $6, so you can change calibers quickly, and not disturb setup on each by moving dies around. I've used my Lee press for about 12 years or more, and loaded unknown thousands of rounds on it. It's ther best buy in reloading, but often overlooked for pricier presses that advertise more.
