For folks wanting to determine different powder capacities without all the drilling etc, I forgot to mention that the Lock-N-Load 450b case is perfect for this. The back of it is drilled out and tapped for the use with the Lock-N-Load assembly already and it is toleranced so different bullets can be slid into it with a little resistance. Once you set your bullet to the depth you're interested in checking, you can throw a wrap of tape around it to keep it more firmly placed while you tamp in the powder. It is not expensive, something like $5.00. Midway has them on clearance right now for $3.18 and if you have the Lock-N-Load assembly, you can check your rifle's leade with different bullets. It's a useful tool for any reloader and cases in many other calibers are available. I have one for each caliber I load.
