Bipod bounce?

My friend Matt and I were talking about bipod vs tripod while at the range a week or so back. I was shooting my Alpha Wolf with .30 barrel with a bipod and rear support. Matt shooting his new .30 Ghost off a tripod. Both shooting Zan 56gr pellets in the 880-890 range. Barring the electronics vs manual factor between this two airguns I feel they are essentially the same. Both use the exact same barrel from Daystate. We were both using a STO Falx for moderator.

At 50 yards we were getting comparable groups, but at 100 his Ghost was just able to group tighter.

While shooting off the bipod I found it hard to get any preload on the gun as the bipod legs would just slide forward a bit. When I would take a shot I could just tell in the viewfinder there was more movement than I wanted. Moving over to Matt's Ghost on the tripod I felt more stable with the preload and the shots felt more stabilized with less scope movement after the shot.

For the record, I do most of my shooting at home off a tripod, so I am much more practiced off a tripod than a bipod. I am sure that plays into this, but I started digging around the Googleverse and came up with several videos and articles from reputable PB sites discussing bipod bounce. The description of bipod bounce correlated a lot with my experience. The surface of the bench at Matt's range is wood covered with 1/4" foam - kinda like the indoor playground tiles you can buy for kids. The benches at the public range I frequent are wood.

This leads me to a bunch of questions, and I wonder if this is inline with what other experience:
  • Has anyone experienced bipod bounce? If so, what have you done to resolve the issue?
  • Is this really a thing off wood and cement surfaces?
  • Would weighting down the bipod (maybe sandbags on the sides) help?
  • How do you get some preload on the bipod when the surface allows movement and slippage?
  • Is there any proven track record that bipod/rear support is more accurate than a tripod off a bench?
 
The only gun I own that gives significant bounce is my FX Boss (.30). If using a bipod I've been able to counteract bounce by just letting my left hand rest on my scope (at my wrist). I only do it for 100+ yard shots. Really comfortable, for me & significantly improved long distance accuracy. I guess one COULD weight down the bipod but my method seems to work & have no added weight to carry.

I'll give that a try, thanks. Clearly don't want to weigh down the barrel so was trying to find a way to keep the front down.
 
Here is my setup for the Texan .257 LSS, which as a bit of recoil. I shoot 85 grain slugs at 3100 psi.
3/8 inch Cork strip matt for bipod skis.
Custom modified 8 pound inverted shooting rest with 3d printed holder/picatinny adapter.

This setup works great to reduce bipod bounce 90 %

Im seeing guys with brass, copper, and steel weights attached in many different formats just for this reason claiming better scores. A very cheap and easy way is to put some weight on your bipod legs or as I have done (to try, not proven yet) bought a 5# dumbell, attached a 30mm scope right to it to attach to a lower pict rail so its easy on and off. Not sure where the weight needs to be or if it matters but half or more than half of the bench guys I shoot with do this in some form.
