I used them a couple of times last year in my Omega. I dropped a Mulie at about 70 yards . He never took a step, he was just knocked down and didn't move.. I have been practicing with them in my Triumph. They are extremely accurate out to 200 yards. That's the farthest I've shot them. I have shot both 250's and 300's. Bonded and regular. I like the 250 bonded personally. I plan on hunting with them during rifle season. My wife is shooting 295 gr. Powerbelts in my Genesis and always 100 grains of 777.I've taken 7 or 8 deer with that combination. You can shoot powerbelts with more than 90 grains,I always have. I switch to conicals and round balls in my traditional guns during Muzzleloader season and for my Refuge hunt..I'll let you know the results of the Shockwaves in a week or so as Doe season is Oct. 4th. I'm looking forward to venison steak that night Lord willing
