Hi Turk,
Glad the moulds came out ok. With densities and volume, you will find in most cases, the densities are listed as a range of figures rather than one set figure to account for batch variation. Also remember that the relationship between volume and density is effected by temperature which could account for you being slightly under in quantity.
CS25 is quite a soft silicone and for most people this is ideal, although often for far more complicated shapes than you are doing where the flexibility is great to get the parts out. Our AS40 Addition cure is a fair bit firmer at Shore A 40, but is also a bit more expensive. Realistically for a simple casting I think you will be fine.
What altitude are you at? sometimes that can effect the gauges a little. If you're not especially high, then it sounds like your gauge has had a heavy knock to be off centre like that. If that is the case, contact me or any of our staff and we will happily replace the defective gauge.
