I agree with the above posters on not actually "saving" any money by reloading because, as has been stated numerous times, you will shoot more.

I got into reloading recently myself and did the same calculations that you are doing, and yes, your cost per shot will be considerably less than factory ammo. I have been watching for sales and buying seconds bullets, and I have gotten my cost per shot for premium reloaded ammo to about one fourth of what the same quality factory loaded ammo was costing me.

As an example, I am now reloading for a 9.3x62, and my cost per shot when loaded with Nosler 250 gr Accubonds is under a dollar. Factory loaded Nosler Accubonds are nearly $4 per shot.

I was told this and didn't believe it, but reloading is addictive.
