I have a Contender 14"SS with a Nikon 2-8 scope.
Best load I found is

120 BT
34.5 grs Varget
Federal Case
Federal GM210M primer
COL 2.864"
best 3 shot group at 100 yds .225"
Excessive muzzle flash

120 gr BT
35.0 grs RL15
best 3 shot group at 100 yds .700"

120 gr BT
33.5 grs IMR4895
best 3 shot group at 100 yds .747"

These loads are safe in my Contender, work up carefully!
Hope this helps.
