Maybe a foot or so more depending on the rodent.but in my experience it's not effective past 5-6 feet or so.
I like those stories. I never grew up on guns so I have fishing memories. My brother had those air soft guns in our teens so I'm kinda late to the gun party but better late than never.Oh yes, rat shooting. I'll skip the story unless somebody wants to hear it, but I set up a Remington Nylon 66 with a flashlight for night hunting rats.I thought this was the bomb until I purchased a Remington Speedmaster that cycled .22 shorts. Many Saturday nights with my brother killing rats numbering into the hundreds. He used night vision goggles and I used the flashlight to silhouette the guns sights. More effective than birdshot and rarely shot holes in the barns.
