I don't want to get ranting on it. But tracked a very large Vermont buck on a single digit snowy day. Buck was shot following year and was 136 inch rack with a close to 200 lb body. That's very big up here. You know the type that holding the gun creates frost on the area your holding. Caught up to him and shot no bang, ran 4 more primers through it no bang all the time the buck has no clue I'm there and continues to feed while it snows and blows. I had a similar experience the next year on a doe similar weather. Might of had a bad batch but I must have shot 20 rounds at the range no issue. Cleaned everything including breach plug as specified by black horn and hunted a week later no boom boom. I've heard 100's of story's about how great it has worked but that's not my experience so I don't shoot it. Went back to 777 and not an issue since.
