I've tested four BCA grendel barrels, one of which I kept.
I shot SSTs through all but one, and all of them HATED SSTs.
The first two barrels were M4 profile and they shot about 8-10 MOA with SSTs
The one I kept shoots better with 100 grain Wolf Steel cased ammo than SSTs, but it will at least hold about 1 MOA after breakin with ELD-M so I kept it.
It's really frustrating because I can go from repeatable 1-1.25 MOA 5 round groups with ELD-M to 4-6 MOA groups with the SST.
I don't know why it be like that, but it do.
