I weighed one of mine on a postal scale. A empty one, then a full one. Or I should say half full. It was ten ounces. I sure like the stuff. Shooting 100 grains with the 200 gr sw. I have just shot two groups at 200 yds. The first one was 1 1/8 inch. Today it was 1 3/4. There was some wind that spread it a little horizontal. 6 1/2 inches low at 200. Should be a good deer load out to 200.
