Ive had Bs in .22-250, .243 and .280.
They aint bad but they do hit harder than they should IMHO.
Pad or fit? I dunno, all of mine (even my .308) are/were red pads.
FWIW I find Remington 700s to fit me well and the factory pads in 7 and .300 mag were decent enough.
The Tupperware stocks w their pads in .243 comfy.
Think the HS equipped stuff may have had some pad like (or actually of ) Pachmayr Decelerator.
The boat paddle 77 Rugers had a chunk of radial tire for a pad LOL
