ahhhhhhh the 90 case answers most my questions. thanks...i know my 120 case has bookoo room for about as much powder as i wanna play with but makes a great cookie case...i use a roughly 3/8ths cookie in it with the 110 grain compressed load...ya know it when you launch a 540 grainer from rcbs mould with this amount of compressed powder but its very tolerable and aint nuthin like the beating i take from some warmer loads in my #1.
