BTW, I have seen several Ferlach made .375 H&H rifles on opened-up standard length M98 actions, made in the 1960s-70s, that suffered from the same problem of lower bolt lug recess set back. Really beautiful, fully engraved custom rifles, but in opening up the actions and filing a working feed ramp, those Ferlach guys removed as much metal from the receiver ring that only the outest edge of the right/bottom locking lug was still supported by the remains of the recess.
