Sheesh (blush)......methinks that Dave has overstated my "sterling qualities" just a WEE bit.
However.
Phil, you say "not possible, unless using a battery of moulds...". It IS possible, and with only one $15.00 mould operating. In actual timed testing over quite a few years, I've found that using more than one mould slows me down, due to the increased number of hand motions involved.
I'll claim it again...with ONE single-cavity mould, nothing special, (Lee, Lyman or RCBS), and using a process I've cooked-down over a lot of time, I CAN turn out over 250 good bullets per hour. How good is "good"? RCBS 416-350s with a MAXIMUM spread of less than one grain over the production run, with visual inspection only and very few rejects. Or, RCBS 515-560s with similar spreads. Or, ditto for MULTIPLE-cavity moulds, for example a run of Lyman 'Loverin' 311467s (about 175 grains) a short while ago, with extreme weight spread of less than one grain from FOUR cavities.
On a timed run of 30 minutes a couple years back, I cast 159 good .30-130s from a LEE single-cavity mould. Yep, that is a tad over five bullets per minute. Bigger bullets take a bit longer due to more time needed to fill the mould each time.

When costing-out those big fat rifle bullets from commercial bulletmakers, consider that the $126 figure I mentioned for 1000 Oregon Trail .45-405s will buy a Lee electric furnace, AND a couple of moulds, AND a Lee sizer or two. What's to lose??? I don't use much Lee stuff for actual handloading, but I've had great results from a lot of their moulds. Although I prefer iron for my moulds, I have a dozen or more Lees that get regular use as well. One of the .45-400 hollow-base Lee designs does very well indeed in my .45-70 rifle. Others report excellent results from the Lee .45 400 non-hollowbase design, as well.
It's a wonderful extension of the hobby, this bulletcasting stuff. Highly recommended!
