is there a .pdf or spreadsheet somewhere that lists a given caliber and then what it takes to go to other cal.s?
ex.
.308 to .300win..
.308 to .300 whisper
.243 to .270
.243 to .308

I go by the pawn shops frequently and I seem to always find good deals but never something I want. Today I found a stanless 30-06, although i don't care for the cartridge, it was a good deal. I've seen posts that have guns starting life as one cal and ending...I should say "currently" another. What does it take to do this? Trying to find a cheat sheet, if you will, for caliber conversions.

thanks
