If you told us the brand of your Walker, we could likely recommend a mould size, bearing in mind that there will be an inevitable, though small, amount of shrinkage as the ball cools down. Most Uberti .44cal revolvers, regardless of type, like a .454" ball. The Walker seems to like to shoot around 45 - 50gr - the effect is the same - lots of smoke and flame.
