I hunted for years with 7mm Mag and 160gr Nosler Partition handloads. I then migrated to 175 Gr Partitions and ABLRs. Both worked very well. Believe Nosler provides a factory 175 Gr ABLR load.
I've used Rel 22, 25 and H1000. My best results are with 93 hrs Rel 22 behind 180 Scirocco. MV is chronographed at 3380 fps. I backed of to 90 hrs for 190 Nosler Ablr and got 3145 fps. New to this forum but, like the articles I've been reading. Jay
