This is a bit handloading oriented but I think it may fit up here in rifle country a bit better since it's involving a specific platform.

I've recently acquired a super nifty Uberti "baby block" in .357 magnum. I no next to nothing about this platform and thus have a question about loads for such a rifle.

My brain tells me that being factory chambered for .357 any loads within SAAMI spec should be fine. But holding this svelte dainty firearm my gut tells me I should worry about my 158grn 16.5g of 296 load I shoot through my marlin.

What's the consensus on loading for such a rifle? Or please share any other rolling block specific tips I should know.

Italian guns are proof tested for use with standard SAAMI or CIP ammunition.
I don't know the pressure your load develops.
A rolling block is a strong action by black powder era standards but when one lets go, you don't want to be holding it.

296 is the same as H-110...right? If that is the case, and I believe it is, you should be fine. If you wanted to, I think you could work up to about 17.0gr (according to Lyman's 49th Ed.) and still be okay. Just make sure and work up to it first.
