Head space comparator gage

[rdhem2]

J. Scott, Sir:
I am afraid my band wagon follows High power.  A rimmed cartridge headspaces on the rim.  You must be short sizing them and allowing the small case shoulder to hold the cartridge where you want it.  That seems to me that this arrangement would be more conclusive to the dreaded misfire you speak of.  A hard primer could cause the cartridge to ride the firing pin forward mashing the case shoulder into the chamber neck and deforming the brass.  

I do not think the .218 Bee is a high enough pressure cartridge to worry about case separation unless the brass is really old and work hardened.  After all it was pretty popular in the Winchester M92 and I believe your Contender to be much stronger then a M92 in that respect.

Now if you wish to speak accuracy you may have a point to having the round tightly fit the chamber.  Being a single shot, cycling function is not part of the equation so a stiff closing is not relevant.

I guess what threw me was the long protrusion of the gauges actuator rod.  Now seeing what it does I probably would have made the holder longer to protect/hide the shaft.

Just my two cents worth.          

You would hate to see a full dollars worth!
