There is drawing of the case on Ammoguide.
It is 3.25" long, with .653" belt/rim and .634" base.
I've put it in P14 Enfields, Ruger77, FBW Model S
and Model L Falling blocks, in a NEF single shot,
in a OlyArms BBK, and big MRC PH bolt gun.
It'll work in any big bolt that 505 goes into, as
picture shows the same length for bolt gun
mags and of course single shots no problem.
I can out run Trex with one in any model gun.
And belted case design last for many firings.ED
