WWE and Bob R -
20 rounds won't last you very long at a shoot. Where I shot regularly, several years ago, we had six steel targets set up at ranges from 100 yards to 600 yards, 10 shots per target = 60 rounds minimum for the shoot. Throw in sighters and just for fun rounds and you're looking at more like 80 to 100 rounds. And THAT is the reason most folks load their own. For my 45-70's, I have shot nothing but BP and bullets I cast myself. I bought 200 pcs of brass for each rifle and never, ever shoot them in the other rifles. I'm still shooting the same brass as when I first started. with probably well over 20,000 rounds total shot. I shoot real BP, I don't resize and I don't crimp, except for the levergun, so the brass will last a long, long time. I can load for my rifles at about $15-17 per 100 rounds, components only (not counting my time and casting electricity) - a far cry less money than buying factory rounds at $30+ per 20. Granted, I got onto a bunch of lead at a real good price, but rolling your own is a LOT more cost effective than not.
