Someone on here was good enough to make me a jig for holding 30-06, and another for 223, for cutting cases shorter.
Only one problem - These jigs are FAR too wide to be held in the Harbor Freight chop saw I bought.
The other photo won't upload (weird and annoying.) It shows that the plastic jig is ~1/4" wider than the jig will hold, otherwise the same.
This has been pretty maddening...
