I'm pretty sure Silvertips aren't loaded with black powder.
35 - 38 grains of FF or FFF is about all you're going to get into modern solid head cases. A little compression is good, but DO NOT leave any airspace. If you use less than a full case, use some kind of filler, such as corn meal or cream of wheat to take up the excess space.
