I got out a few of my manuals so that i could provide you with the information, but by golly it ain't in a single manual i looked through. No doubt that rather than reading it in various manuals i have read it on various forums, or the only other explanation i can offer is that i was perhaps thinking of the opposite of what is being discussed such as the spring back in the chamber after firing the round.Uniquedot: first I must ask you what manual mentions case springback and I need the Manual name and page # where it states this information.
The reason why I insist on this exact reference is because several people on this thread have stated that they read this in a manual or Handloader Magazine. Or "so many manuals state this."
Yet when I look at the articles mentioned there is NOTHING IN THESE REFERENCES WHATSOEVER that says or even implys that this problem exists. It's like somone is not understanding what they read.
Colorado4wheel, as i stated to W.R.Buchanan when asking him a question... i ask you this question to get legitimate knowledge and not to continue an argument. If you have male and female parts of the EXACT same size would it even be possible to fit them together without force? it seems to me that there would have to be at least some minute tolerance between one or the other in order to fit them without forcing.
