Mike, what timing.

Funny you should mention this because I was at an NRA dinner last week and I won one {I also won a shotgun...!} in a lottery drawing. I would never have bought one because I have always feared the broken stock issue and I am thinking of selling it because of that. But it was a free deal so I took it.

For one thing, I have to wonder about the POI of a rifle that is zeroed in the sled and then shot from the shoulder. With a heavy double shot only at close range that might not be a problem, but I'm not sure.

The other issue, broken stocks, I would think might crop up either at once if there is not enough give and the recoil is severe enough or over time if many shots are fired either at one setting or cumulatively over the life of the gun. Trouble with the sled is that the shooter really doesn't know what is happening until...that nasty little line shows up at the tang, wrist, etc and then of course it is too late.

I know that broken stocks have forever been an issue with military rifles firing rifle grenades, particularly when the gun is backed up with a brick wall, curb {verge}, hard ground, etc.

I'd be interested to hear what others have to say about this topic.

BTW, I know a fellow who has one {I've never shot a gun from the sled} and he says just like you the thing STOPS recoil, and he has shot a number of slug guns and says in total agreement with you that the things can be shot all day from the sled.
