.177 Polymag at 925 to the ol’ thoughtbox did the trick. Shot another one last night that entered the shoulder, went through the body cavity, and exited the belly. Both equally dead. Seems to be good rat medicine if the vitals are hit…
That sure left a mark ! I'm getting around 670ish w/ 17 gr Apolo wadcutters out of my Kral NP03 (1ft from muzzle) & they exit front shoulder to rear ham at close to 20yrds. My ratting never gets beyond that distance.
