Well, I read your post with mixed and opposing thoughts. On the one hand you are trying to save money by rolling your own while you are shooting more. I consider handloading strictly a hobby. I take my loading seriously so don't get me wrong here, but if I tell you that I save one red cent by reloading I'd be lying through my teeth. I have spent so much more by handloading than if I just went and bought the ammo that I can't even fathom the sum of it, and that is buying $50+/ box of shells for my 338RUM. Now if you want the enjoyment of doing your own ammo thats great, although I have to warn you that this pass time is addictive and you will start out being frugal about what you need to just get the job done but as you get further into it you'll realize as I have that you have to feed you're habit. I started out with just the basics, single stage press and press seating primers, no frills cause I was watching the spending. Yeah right, now I have a progressive press and every time a new reloading tool hits the market I see if there is any way I incorporate it into my process just to give me an excuse to have it! Stark raving mad? You bet. I won't even waste you're time or mine telling you how much you'll spend for the cartridges you mentioned above. All I can say is try it you'll like it.
