Apologies if this is addressed elsewhere: I did a search and did not find anything exactly answering my question.
Given that many reload to save money (as I do), and given the rising cost of components, one way I would like to save money is by reloading rounds with which I can "double-up". For example, I can reload both .357 Magnum and .38 Special with the same set of Lee Carbide Dies. This saves money because I dont have to buy any new dies.
What I would like to do, eventually, is begin reloading both 9mm and .357 Sig. Currently I do not have firearms for either of those platforms, although I have plenty of brass saved from the range for both. Many have said that the .357 Sig is a 40 S&W necked down to take a 9mm. However, this is of course not entirely correct:
9mm Luger bullets are listed as .356, while .357 Sig are .355. One of the reasons I thought I might be able to save money (albeit probably not much) would be to use the same bullets for both, by buying in bulk. However, then I discovered that the bullets are two different sizes, though only 0.001 apart. Does this really matter? Are the bullets interchangeable or only one-way or neither? Is the difference a practical concern (I dont really load hot rounds) or is it no big deal?
Apologies for my ignorance, I just want to know what can and cannot be done so I can plan what new rounds to expand into reloading.
I already load .40 S&W and .38 SPL... I derived the above information from the Lee Modern Reloading book(2nd Ed.).
