Saving money is one issue, increased accuracy is another. For 9.3x57 it would cost me close to $2.50 a round for factory ammo, I can reload using re-formed 8x57 brass, Speer bonded 270 grain bullets, and CCI primers for under .40 cents a round. It does depend on where and how you purchase your components. I picked up some .308 165 grain SP Combined Technology bullets from Midway about a year back, $4.95 for 50, so I picked up a few boxes. For .308, 7.5x55 and 7.62x51 it now costs me about .19 cents a round to reload. Most rifle cartridges cost me between .20 and .40 cents a round. Plus they are tailored to my rifles! So at an average cost of $6.00 for 20 rounds it is a huge savings. This includes 7mm Rem Mag, 6.5x55, 7.5x55, .308,5.56x45, and 9.3x57. Pistol cartridges are an even bigger savings. I reload for about 7 rifle calibers, and 3 handgun calibers. I use 3 rifle powders and 1 handgun powder. Jim
