If it is a 1:11", stick with 190gr and under bullets. They are plenty for taking elk out to 1000, and will stabilize much better. Had a guy I know take a HUGE moose with the 190 HVLD @ 650ish I think, one and done.
Nosler Trophy Grade have usually been pretty accurate from what I have witnessed. 180 NAB or 190 NABLR
HSM Trophy Gold w. 185 HVLD
HSM Game King w. 180 SGK
