I see what you mean Ian, the packaging contradicts the website, the website shows that 30 mm rings will accommodate a 52 mm objective lens but the 1 inch rings will only accommodate up to 42 mm, as long as yours are for 30 mm then I would assume that they should be ok. Looks like a printing error on the packaging to me.
You would also reasonably expect that medium height rings would be suitable for a 50 mm objective lens.

Ive got a 527 with High warne rings and a 56mm objective scope, there is about 3mm clearance.
So with a 50 mm scope you would have 6mm clearance. The difference between medium and high rings is less than 2 mm so you will be fine.
I also find the barrel profile and length of tube are factors. Short scopes and fat barrels make for higher mounts...
