The best practice is to use the same material for balls and the grinding jar. However it is also common practice, in my opinion, to use "typical" bearing steel balls with a hardened steel jar. You should always take into account the contamination effect (especially when high energy or long grinding times are applied).

Another way of fitting more balls into a radial ball bearing is by radially 'fracturing' (slicing) one of the rings all the way through, loading the balls in, re-assembling the fractured portion, and then using a pair of steel bands to hold the fractured ring sections together in alignment. Again, this allows more balls, including full ball.
