Yep, love the Underwood stuff

Great Ammo for hunting Underwood

NDZ 22 pound spring and Rod kit works like a charm in my G20 Gen 4 .
with Underwood Ammo 200/220gr.

I use NDZ 22 pound Spring and Rod in my G20 Gen 4 with KKM barrel.
Very happy with 220gr Straight Shooter Hard Cast coated and 9.5 of BD here in Alaska.
