If you are shooting supported on the bench with a rest then I don't see why you couldn't have any power you want. I had a 2X on my 6" 629-6 with a Weigand base and standing I could just keep the cross hairs from swimming in front of my eyes. I went to a red dot and found it to be SOOOOOO much easier to focus the dot on the target and squeeze. I know you said you don't want a red dot though. Just offering my experience from having done both.
