You're not going to safely get 1900 fps with a 180 bullet out of any .357 magnum firearm.
The question wasn't whether or not the cartridge is capable of taking deer but is it legal.
In NM, ANY centerfire rifle or handgun is legal for deer and ANY centerfire rifle or handgun over .24 caliber is legal for elk.
No energy requirements on either
