If correct, this estimation seems to be within specifications for this rifle, so I am very pleased!
The only thing I did differently from the instructions is that to get a spent primer (which I did not have), I removed the bullet and powder from an unspent casing, fired the PRIMER ONLY and removed it to use for the measurement. I used that same casing for the measurement as well. I assumed that the force from just the primer, with no powder or round, would not cause deformation on the casing, and it could still be used for the measurement. If this is inaccurate, please let me know.
As a non-reloader, the best thing I could find to remove the primer from the casing was a straight shaft gasket puller. I filed the sharp point on the end to approximately 1/16”. It worked very well.
Many thanks!
