In NH in the regular season he is A OK. Restrictions are no 22rf, no smaller then 00 buck. Stupid OK as the 17 hmr is okeydokey legal for deer [from the legal dept. of NH F&G]. In ML season single shot rifle, smoothbore, Pistol. One may have a SS longun and a SS pistol together. Only exemption in ML season.
No ever said the F&G guys are smart.
