I've heard of stocks often cracking from using the lead sled. I've talked to a gunsmith that told me that it happens quite often. It only makes sense. Without a soft shoulder there, something has to give.
I've never understood the use of one of those anyway. I can understand the use of a bench rest for temporary sighting in but when it comes down to it, you don't have one of these things in the field so why even bother? Just rest the front and back on a bag, shoulder it up and shoot like a shooter, not a machine! ...but that's just me I guess.
I so often see guys at the range shooting over and over and over in one of these "carriages". It makes me wonder if they're using it to eliminate the felt recoil altogether from the rifle they're using as opposed to sighting it in. I mean, c'mon, it can't take THAT long to get zeroed in! (unless one doesn't know how to mount a scope...but that's another subject)
