I’m really having an issue with seating my rifle (rear bag) I bench shoot not prone ,I’ve been threw numerous bags including making my own.I know its me it appears that I’m doing something wrong can’t seem to keep the rear of stock stable it slides either forwards or backwards.Could use some advice on what I’m doing wrong.Bergara HMR 6.5cm
 
Fill material and fill volume both play a big role. Bag shape as well. A soup can shape is my favorite by far. Are you properly squeezing the bag to firm everything up before the shot? The rifle should be able to freely slide backwards and forwards during recoil. I’ve used everything from sand to plastic BBs. Rice is one of my favorite cheap light fills if the bag won’t see water. For a bag that might get wet I have some with whatever light fill Armageddon Gear is using. Sand is by far the best stuff if you don’t mind the weight.
I also use a Protektor leather bag when shooting off of a Seb Mini rest. They are extremely firm and in that setup all adjustments are done with the joystick on the rest.
 
The big factor also is what type of stock you have or if you have multiple rifles with different stocks? For instance, the Vision Pro has an flat adjustable bag rider, I use the Protecktor Brick bag with that as I'm at the bench and in conjunction with the bipod, I can adjust the rider height to make it so there is very little movement needed to make minor holds for wind and height with the V22. While the TAB rear bag would work the same, I like the smaller width of the brick bag. I do like the "soup can" bags as SC described above, I wish the one I had (TAB) was the size of one though and the TAB bag a little narrower. Like some other gear, you may cycle through and end up with a few types, rifle type and stock style will usually "need" different ones. Now, if someone made a Cambells size bag vs. Progresso---

I just dorked around and used a leg of some old dungarees and 10 lbs of rice to make a front rest for just that. On that topic, I don't mind spending money on "things" but these jokers charging 100+ for a decent front bag are smoking some serious dope.
The Wiebad and Crosstac stuff(most of it) is reasonably priced, although those Wiebad cheek rest are over priced in my opinion.

qoute above is a huge factor.

Howdy @Jpducks, I know that this wasn't necessarily what you were asking but just wanted to share a link where we were discussing rear bags recently and hopefully there's a nugget or two there that may be of some indirect help to you.

Wishing you the best of luck either way.
