Converting Brass from one caliber to another caliber
Hey guys, I heard of coverting 284 Win to 7.5x55 Swiss and it makes me wonder, "What other calibers can be done the same way?"
So, how about making a list of what you guys know? Here's what I know off the top of my head:
284 Win to 7.5x55 Swiss
.357 Mag to .38 Sp
30-06 to 7.7 Japanese
.32 S&W to 7.62 Nagant (I could be wrong)
9mm Para to 9mm Mak
10mm to .40 S&W
Help me add to the list!

Be very careful. Just as one example, 9mm to 9 Makarov. 9mm brass varies tremendously. I once measured and weighed my range pick ups and found, out of over 1000 rounds, not one was the specified length, the shortest, if I recall correctly was .730", this on a round that supposedly headspaces on the mouth. The real problem was in the weight- the heaviest was 50% more than the lightest. If you realize that internally the walls are tapered and the fact that a true Makarov bullet is .363" in diameter, you can see that pressure might be more than a passing concern.

There is an excellent book Handloaders Manual of Cartridge Conversions by Donnely but the only time it is a worthwhile endeavor is if brass is not available at all.

.30-06 to 375 whelen, 35 whelen, 338-06, 8mm-06, 280 remington/7mm express, 270 winchester, 25-06.
.30-40 krag to 445 supermag
.308 to 44 automag
there are so many more
but when going from 10m to .40, the case will be thicker so pay attention to pressures.
