I feel your pain. I have a sweet little Browning A-Bolt Micro hunter in 257Rob that has the same issue. I was lucky to find a 100gr Nosler BT load that shoots under 3/4" but everything else is like yours (1-1/2 to 2").
This load has killed a big buck and a few hogs, but I'mm bummed at the lack of bullet options.
Oh well...not going to mess with mine.
Good luck with yours.
