All, I was hunting with a buddy who always keeps a couple rounds of birdshot in his 38 revolver for snakes when hunting. Of course I ran into the rattler with light getting too low ans a 270 and 45 as my defense. From where the 45 rounds exploded I must have taken some good chunks out of the snake before it went away. Had I had some #9 shot in the 45 I would have stopped it right away. Does anyone know if those pistol shotshells come in 45 auto and if they will cycle my pistol. It is a stock RIA with stock springs.
