I do think your sliding and bouncing front rest (and maybe your rear one) are definitely adding massive noise to your reloading analysis.
This is what I do to counter shitty range benches that don’t allow me to get square behind the rifle:

Rotate them 180°. Use a good bipod, and do what Frank and Mark teach at their classes: clamp a piece of wood down to get your bipod some purchase.
The Phil Velayo vid above has that exercise to teach you how to not overly load your bipod, and that comes in handy when you have a solid setup to push against. Don’t overdo it.
I now also use a piece of tough welcome mat to better replicate dirt (deaden bounce). It seems the vast majority of PRS shooters use the stock rubber feet, according to that PRS blog “What the pros use”.

I use Frank’s bench method of leaning in at the hips and squaring up, all the better to replicate prone (which I cannot actually do due to my neck).
1) square up, do Phil’s bridge technique
2) hands off gun, aim gun with body, notice if bipod is binding. If so, re-square bipod to target.
3) add grip hand, pull back into shoulder
4) breathe; see up/down reticle movement (Phil)
5) if ret movement isn’t plumb, you’re not square
6) slide rear bag in, pull up slightly and squeeze to limit reticle heartbeat bounce
7) shoot
Early in my journey, I tried a Bald Eagle front rest with a Protektor front bag and a Protektor 13b rabbit ear rear bag. Hated it. Felt like I was in a box, not connected to the gun or to shooting. Felt like the setup was trying to get the human less involved (not more) in the event. Yuk.
But maybe you’ll find that’s your thing. You’ll just have to experiment. If you do go squeeze bag, get a Mark Taylor one
@Enough Said. Best one I’ve run across (tried Tab and Precision Underground). I can’t quite tell what kind of rear bag you’re using.
