A:
This table should be able to handle the standard (original) lead sled, as it's total length is listed at 27", and this table has a surface that's 34" long, but you may have problems if you have the lead sled FCX and it's at it's fully extended length of 34 3/4".
One thing to be mindful about is how much weight you put on it the stable table. The specs say it's only designed for 275lbs, so if you put your lead sled (16lbs) on with a full 100lbs of lead, plus your rifle with all its accessories, a few boxes of ammo and other various items, then include your own weight, you'll probably be tipping the scale past the 275lb mark.
