on high powered bolt actions rifles, the lead sled works well,,,,i use no extra weight on the sled and also hold the fore end with my hand, in front of the forearm pad,,then go to the bags,,shoots the same except get a better groups with the sled,,,,have done this many times with many different calibers,,,i have read that the lead sled sight in, will not be very close to shooting over bags,,i think thats because people shoot worse using the bags,,,,sight in is sighted in,,,,,,

It’s the Harrington Effect, first documented during acceptance tests of the M16 in 1964.

Never had an issue with 338 lapua or mag rifles. Never thought of using a recoil sled for smaller calibers. I'll have to try it with the ak-74 and the AR 15 just for fun.

I know that shotguns slugs are effected off a bench rest, best to Zero those slug Guns in the sitting position or steady them on the side of a tree, especially semi autos, just not a bench rest.

Hate to be that guy but I believe operator error is playing a part in this your groups with a bipod are within an inch ish how from a support with no sway are your impacts varying more than 1 moa and bigger than your semi supported shots I could see there being an issue with overall sight picture if it was the same grouping but an inch lower however the groups have now spread out. My guess is that the sled itself was not level and that is was digging which would explain a radical drop In elevation not windage

I just got off the phone with a gentleman from krieghoff barrels, top tier barrels! He said led slefs ruin scopes and destroy accuracy especially when the barrel gets hotter. Much harder on guns and changes the barrel harmonics as in changing the part of the sine wave where your accuracy node is if have actually tuned to it. Hard to find that g spot without proper hand load work up or ammo selection.

Do you have an opinion as to why this happens? Mag slap with recoil? Seems like sight picture (my initial thought), but with continual drop, I'm wondering if it is something else. Thanks! Corey

Corey, thanks for commenting on the video. I don't know why the lead sled affects the AR-15 other than it is in some way altering the recoil impulse and changing the muzzle position when the bullet exits the barrel. The only thing that could contribute to this or cause this is semi auto action of the AR-15. It would be interesting to set up a high speed camera with a grid background (like on mythbusters) and see what's going on.

I've seen on a few other videos where they are building up the recoil padding. It appears as though there has been a few issues with "un-true" results because the sled doesn't react like a human body, hence the addition of more "padding". Seems like people are using (from videos I've seen) more addition of foam to the butstock area. Thanks for the reply! Corey

This is good to know... I've been pondering getting a sled. This is just another strike against them for me. Do you have any concerns about where the energy for the shot is absorbed into? I've heard of guys wrecking the stockss of their rifles because the sled doesn't allow the energy to escape so the stock takes it all. Might not be an issue on smaller calipers, but getting into the 300 and bigger could be risking your rifle by using the sled? Thoughts??

Branon, I can't imagine the lead sled ever damaging a stock on any caliber of rifle. Even though it can be weighted, it still is able to move under recoil. Thanks for the comment.

On a standard lead sled the pistol grip of a AR is known the touch the brace that connect the front rest to the stock rest. The DFT has two braces that will allow the AR pistol grip to fit between them. Check this video out at about the 3:50 mark kzitem.info/news/bejne/y39n3Hyfi6Ghl5w
