Any opionions out their on this ?
Never put a cheap scope on a big mag with/without the lead sled.
Yes the rifle ends up absorbing more shock than it would against your shoulder, but if you are developing loads it takes usually quite a bit of shooting and with big mags sooner or later you are going to start flinching, pushing, or wrenching which makes it very difficult to (read impossible) to really see which loads group the best consistently.
In reality though the sled ends up taking most of the abuse, not the rifle.
If your rifle, mounts, rings, and scope are all of high quality and properly mounted/installed and maintained it should not damage any of them.
Once you have two or three good loads, then put it to your shoulder and see which works best.
