The info in this Olympic pistol post may be useful for bullseye.
Please note, some have felt the base post is worthless or counterproductive, at least for olympic pistol use.
The ammunition sorting methods described in the posting can be tested for your purposes with a trial group of 10 cartridges or 30 cartridges, using the rules of Poisson or Gaussian statistics, respectively. If there are no "deviations" from the standard after 10 cartridges, chances are at least 85% that no deviation will be found in the next 1000. If there are none in 30, the chances rise to 99% likely that all the others in 1000 will be within the required measurements.
