This post is intended for PCP guns that are designed for short range as in inside a barn. Any where normal penetration is not needed , or desired. I know there are springers that work great for this type of power output. This is for PCP folks that sometimes are in a situation where " less is more" . I will start , my recently acquired Kral NP-03 will adjust down to 10 FPE with 25 cal JSB pellets , which goes a LONG way to prevent punching holes through a barn wall. So , what is your choice for this type of task?
