Heavy duty anchor for old cinder-block wall?
I need to secure a shelf to an old cinder-block wall. My experience with these walls is the anchors frequently work loose due to the low density of the block.
I want the shelf to be able to hold 100 pounds, so I need a strong, reliable anchor.
Any suggestions?
Thanks!

Using a VSR drill with a masonry bit going slow might get you a hole that wouldn't be oversized and lower any risk of breaking the block sidewall.

I use the WallDog sold in Lowe's. They DO work. It's a Screw and Anchor all in one for drywall, brick, metal, concrete. I work for the company...LOL.
In my demonstrations I hang a 50 lb. box of nails from one in a cinder block. I think they'll hold up to 500 lbs. in concrete.
In sheet rock they'll hold up to 50 lbs. I use them to hang my medicine cabinet, mirrors, towel bar and toilet paper holders instead of the anchors they send with it. I recently put up shelving into sheet rock with them and also hung my curtain rods with them.
They even make ones to hold 250 lbs. in sheet rock.
