This is the round for the P90 PDW (personal defence weapon), Yea, you could use if for pest control, but at $1300+ for either the rilfe or pistol, I think i would find a lower cost solution. In addition, ammo can be a little difficult to find, and expensive when you do find it. In addition, FN will only sell certain rounds in the U.S.
I would hate to reload for it. I picked up some FN 5.7 brass the other day a guy was shooting who does not reload. Figured if I saved enough of it I could sell it :lol: itty bitty stuff.
Most velocity figures you see are for 10" barrels. If you had a small 16" or 18" carbine you would pick up some velocity. Would be good for plinking and varmint shooting if you don't mind reloading.
