My daughter (grown) shoots a 30-06 with 125 gr core-lokts. My grandson shoots a 243 with 95 gr hornady super-performance rounds. Those two are DRT rounds to beyond 200 yds. My low-visibility brush gun is an SKS with soft points.
Probably a Cuban treefrog. Saw one near Perdido Key last year. UFL wants sightings reported.
"Any treefrog in Florida that is larger than 2.5 inches is definitely NOT native, and is probably a Cuban Treefrog." https://ufwildlife.ifas.ufl.edu/frogs/cubantreefrog.shtml
I am not a gunsmith, but it seems to me that a 9mm could be converted to a 30 Luger pretty much by swapping out the barrel. And 9 mms come in many more flavors than the new cartridge will ever be used in.. Just seems like a lot of trouble to go to for illusory or marginal benefit.
I had some stored in the garage for a couple of years and they went foosh rather than bang and badly fouled the barrel. I live on the water. No issues with the primers. I store them inside now and have dessicant in the container. However, I take new everything hunting.
I drove down Jack Springs road on Sunday on my way back from Stagecoach Cafe in Stockton. A mobile home park just north of the Poarch complex got walloped.
The center fires probably have a heavier trigger pull than the .22. Might dry fire with them until you cannot detect sight movement when the hammer falls. Then put a red dot on one of them and dry fire it until the dot doesn't jerk when the hammer falls.
Will take about 2 years.
The OP indicated there might be some skepticism.
When I first started shooting pistol silhouette about 25 years ago, I was already a master in NRA bullseye and ISU standard pistol and the NRA had trained me in Colorado Springs trying to get my air pistol scores up . So I shot my bullseye guns...
Depends on how fast you are shooting it, too. An expert at slow fire, offhand, with a match grade gun and ammo, will have about an inch of dispersion for every 10 yards distance. Probably less than 1/2 that from a rest.
