    Has this happened to anyone before?
    I was recently working up 100 yard loads for an AR 10 style rifle. I decided to use a lead sled to try to take me out of the equation. I made up 9 cartridges of each loading.
    I shot 5 cartridges of each loading and was unable to get any reasonable consistency other than velocity.
    I was confused and frustrated as two of the loadings used to give me reasonable accuracy.
    I then shot the 4 remaining cartridges of each loading with a front rest only.
    Grouping got a lot better across the board on all loadings.
    Any Ideas?

    Lead sled don't settle in the same spot after each shot fired unless you let your inner-ocd take over and make certain everything is lined up again. I've only used them for hard-kicking rifles when working up a load by looking for 'flat spots' in the velocity as the powder charge changes.
    Your best bet may just be to get bags front and rear to help stabilize the rifle and making certain you are doing everything you can do squeeze the trigger the same each time.

    Only thing I can think of is something is inconsistent about your rest.

    Even if I am using one of mine on a plywood top bench so it isn’t really “nailed down” it’s still somewhat repeatable (like the last 3 shots in the same ragged hole, at the end of this video).

    I use a lead sled most all the time. What I have learned is, 1st you need a min of 1 25# bag of shot on it, 2 25# are better. If your not the sled is going to move around freely. I made a holder to set the front legs in that hooks on the front edge of my shooting bench. This works really well on keeping the lead sled from moving. Also you actually want to get behind the sled like it was the actual gun. Pull the gun tight against the rear support, then make the necessary adjustments. Once your satisfied you squeeze off the shot like you normally would. It will still settle and move. I also discovered as you move the windage adjustment this makes the unit move side to side if not in the center. So unless you have it anchored down so it can not move at all, expect movement. The purpose of it is to assourbe the recoil which it does very well.

    The first time I fired my 458 SOCOM on a lead sled, it move my whole bench back, 5 shots moved it 1/2". The bench is close to 100 lbs , setting on the ground, + my weight 150#. I have since put stakes in the ground behind the legs to keep it from moving.

    My newer benches I set them into the ground so they would not move. I could not do that on the bench in my front yard, needed to be able to move it.
