Rear bag rule question -SSR

[SiegeLord]

Hi all

FTR rules question.

Can I use a rear bag thats got a supporting & surrounding box as per the f standard rules? or is it strictly flat plates/doughnuts only underneath the rear bag?

Budgeting for a bigfoot in the meantime
Otherwise my fancy, custom, sand filled sock in a open topped coffin maybe in order

I'm enjoying the discipline greatly but would like to stay ruling/intent compliant.

No, it's not particularly well defined, but the FS rule is an aberration that unfortunately occurred, like the one that granted bipod users extra weight.
