Got one delivered from Midway today and set about doing some measurements on the Savage 12 VLP and associated brass. Anyways. Measure up some brass fired from the Savage and compared it to the stuff I already full sized and de-primed (not shot in my rifle)...what a surprise, there was little to no difference in length..literally .001" over a sample of 10 rounds of pre-fired and 10 rounds of full sized. I was actually a little suspicious, so I dug out a throwaway from the trash can (got a little dented during an ejection) and measured that...0.006" over sized. So, proved that the full size pushed the cartridge back to spec, and that my headspace on the Savage also happens to be right on spec too! Who would have thought! Moved onto seating depth. Jammed a bullet into a casing that had already been fired and that allowed movement, but was restrictive. Popped it into the chamber and did a measurement...reliably came out with a 0.072" over OAL for the V-Max rounds I am using...then did the same with the Precision mic.....0.068" over several attempts....I guess that is a result. And proves that you can measure your chamber depth using a makeshift setup. What the instructions did not make clear was what you did with the number you got from the gauge! I just dropped a pre-loaded round(that was made to OAL spec) into the mic and measured the bullet seating depth relative to the gauges contact point and then took the chamber insert measurement and used the difference between the two. If I did not have the loaded round, not sure what else I would have done!? Anyone do anything different here? I'd be interested to know.
