New Mexico Hunting Laws
New Mexico's big-game caliber floor is low and simple: any centerfire firearm at least .22 caliber, rifle or handgun, is legal for deer, elk, pronghorn, and bear, so long as the bullet is designed to expand or fragment — full metal jacket and tracer rounds are unlawful. Muzzleloaders must be at least .45 caliber, and a stricter open-sights, no-scope standard applies to dedicated muzzleloader-only hunts.

All Weapons
2 rulesNew Mexico's manner-and-method rule defines legal arms by calibre, action and whether they fire from the shoulder, and never mentions a muzzle device — suppressors appear nowhere in the whole part, so the hunting rules do not restrict them for any species. The hunting rules being silent does not settle possession: the suppressor itself still has to be lawfully possessed under federal law and state weapons law.

How to Use This Page
Each rule links to the regulation we read and the month we checked it. Rules marked needs review come from summaries rather than the regulation text, and never produce a green answer in the checker. The checker's energy figures are typical factory loads, so where a rule sets an energy or bullet-weight floor, check your own load's rating. This page covers equipment only, not seasons, tags or local ordinances, and it isn't legal advice. The current New Mexico Department of Game and Fish regulations are the final word.
