I'm showing the Spencer brass 1.5mm or so shorter. I get about 31mm for my loaded .510 GNR ammo and the Spencer says 29.5mm. Not a problem. The rim diameter is a little more difficult to measure with a ruler but it looks like the .510 GNR is 15mm or so and the Spencer specs. say 16.1mm, again about a hair.

There are other dimensions in play but it's close enough to get some and just see. I have made .510 GNR brass from the Linebaugh, Max., .348 WIN., .50 AK. all work fine.
