S.A. 725 already received a vote in the Senate, this is the Grassley-Cruz Amendment offered as an alternative to Schumer-Toomey-Manchin. It received 52 votes
but needed 60 to pass due to the consent agreement. The only amendments to receive less votes were the AWB and magazine ban amendments which failed even a simple majority.
While I strongly suspect that the bill to reauthorize funding in the House will end up looking very much like the Grassley-Cruz Amendment, it doesn't look like that language is going to pass the Senate.
