I've just started shooting and reloading .223 Remington. I purchased a little used late 80's Winchester Model 70 from a friend and 150 rounds of Remington UMC 55 gr FMJ to get used to the rifle and yield some "fire formed" brass.
I purchased a Lyman case gauge and just discovered something interesting. I decided to see if the "fire formed" cases would fit the gauge, using some 75 cases I had de-primed and neck sized (Lee dies). Most were once-fired but a few had been reloaded once. Almost all dropped right in the gage. However, there were two small groups that didn't.
One group dropped in the gauge but stopped with about 1/2 the rim protruding. The other group stopped with about 1/2" of the case protruding, as though the case had bulged slightly. I've never noticed any difficulty working the bolt or extracting a case. I didn't test any of these in the rifle before full length re-sizing them (wish I had).
I had believed that "fire forming" would yield extremely uniform cases for reloading. Are my results typical or should I be looking for something not quite right?
