What exactly are your needs for the 357Max? Heavy bullets for hunting would be my guess since lighter ones for varmints don't exactly seem an application for a double rifle. 125 grain bullets will scream out of a rifle!

I just googled 357Max factory ammo; it appears to be scarce and expensive. I found that 2 boxes of Fed 180 grain went for $130 on gunbroker. Wow!! I still have most of a box of that I got way back in the late 80's. It is a great cartridge in my T/C Contender, but I have been handloading it for a long time. You should really consider taking up handloading for it, particularly considering that factory ammo is scarce/expensive and even brass is sometimes uncommon.
