I doubt this IS the proper place for this BUT it does say barrels! lol I keep seeing all of this here info on TV about ballistics testing on these murder shows and stuff. They take a certain gun and match the rifling on a bullet recovered from a body and then take the supposed gun and fire a round and then match the rifling. NOW my question is that if a barrel is made with any sort of quality control shouldn't ALL of the riflings MATCH IDENTICALLY?? I mean if you take 2 remington 700 barrels produced on the same day one after another with the same tooling it looks like to me that a bullet fired from each should match exactly?!?
