Some of you might already be doing this but here is a way to make homemade
pistol shot shells in 40sw. First, I re-size and prime the case. Then load with 2grains of pistol powder. Then I sharpen the mouth of a 40cal case with a chamfering tool inside and out, using it to punch out paper discs out of a phone book cover. Then, I tamp the paper card wad on top of the powder and fill the rest of the case with 8-shot or whatever size shot I have on hand.
Finally, I drip a couple drops or sealer on top of the shot to water-proof it and hold everything inside. Last time, I used sun-roof sealer for a rubberized
effect. Works great! The shot penetrates pop cans completely and patterns well out of my Glock23 up to 5 yards.They might come in handy for small birds, snakes or rodents. I've been using them to impress freinds by shooting balloons at 10 yards with a super-fast quick draw lol. They think I'm better that Clint Eastwood! They wont cycle the action but they will cycle manually from the magazine. If anyone has ideas to improve my method, please let me know.
