Yep, that says it succinctly.
Everything that was legal before remains so.
The only real change with the newly legalized calibers is that there is no maximum allowed case length, as long as you're using specifically a .243 or.308 bore rifle.
The minimum case length for all standard firearms -- be they handguns, handgun caliber rifles, or the newly legalized rifles -- is (and probably will remain so should they expand the allowed cartridges for rifles to everything from .243 to as big as you can handle) 1.16", with but one exception, that being .40 Smith & Wesson and 10mm Auto in handguns only are both also newly legalized.
.40 S&W has a SAAMI case length of .0.850".
10mm Auto has a SAAMI case length of 0.992".
You can find the pertinent cite regarding .40/10mm caliber on page six of the link in my previous post, but here's the quote from that page:
"The new law also approved use of a handgunthat fires the 10mm Auto or .40-caliberSmith & Wesson to hunt deer during seasonswhen firearms are legal to use. Full metaljacketed bullets are illegal."
I'll probably be carrying my S&W 1006 in its Bianchi shoulder holster this fall in the unlikely event that a deer either wanders up so close that my scoped .30-06 is impractical, or for a coup de grace.
