I'd like to see the packrifle in 38 special. Not a huge increase in PSI over a
22. Still pretty compact and inexpensive ammo. Shotshells for 38 are better
than 22.

38 Special is legal for deer in some states and
better and more humane for jackrabbits and other tough small game. In a longer
barrel they are very quiet too as they travel subsonic. Won't hurt your ears as
much.
