Guessing. Didn't tape it off. Could have been 15'. Hell, could have been 12. Again wasn't measuring. My son was prone and shooting and had ear protection on. I didn't since he was shooting a 17 HMR. I heard the rattler rattling and he was way too close to my son. The 40 shotshell did it's job very well killing the snake pretty much instantly.20 feet away...... I would have thought that would be maximum range. My 38/357 home loads are very effective at 10-15 feet. Going to try cutting the 38/357 capsule down and single load in the 9mm. I'll start at 4 grains of Unique.
