Winchester 92 is a strong action

That should give you some peace of mind.

In the old days Sierra made a 170 FMJ and Hornady made a 180 FMJ, both for the IHMSA silhouette shooters, so load data should be available for them. My understanding has always been that lead bullets have less pressure than jacketed.

I think your biggest challenge is experimenting to find the proper cartridge length to function in that action and still not take away too much of your powder space.
