I have the same issue described here but with the DOVEDV10 plate I received with my 1100GTO in April of this year.  The springs run out of travel before the clamps have fully retracted.  It's not a big deal for me as I mount the scope rings first and simply push the clamps all the way back prior to doing so.  But I wanted AP to be aware the same issue is occurring with the 10" dovetail plate.
