In my opinion it is not too light a cartridge for deer.
Conventional bullets like the 55gr Horandy SP or the 63gr SMP Sierra have proved themselves as quite effective for the smaller deer.
And there are other bullets, like Barnes' or the 60gr Partition will provide the extra penetration with which to feel more comfortable with the larger deer.
Wether it is an adequate choice or not will depend mostly in your markmanship, your hunting style and the kind of terrain you hunt in.
Bearing in mind that no caliber size will make it up for poor bullet placement,
