A couple years back there was a message or two here that included large versions of JGS Chamber reamer blueprints for .223 Rem., .223 Wylde and 5.56 NATO. I think TWEAK might have posted them. I have a reduced size versions that are in my thread about blown primers but with the size reduction (JPG), the text dimensions are not as readable as they once were. The Clymer and JGS web sites don't have the reamer specs online anymore.

I am asking for the information because I am doing a CAD diagram comparison of a variety of 223/556 chambers and would like to have as many as possible to look at. I can't find the old messages in an archive search, probably because I'm not using the right terms, so any help would be appreciated.

J3_,

You are right. That's the big brother to the one. I have that too and will be trying to compare the almost readable numbers on the plans to the numbers from the sheet you've got. Thanks for your patience.
