Over the last decade, we, GMDR, have taken significantly more data
than that listed on our LeverGun Studies/Data pages - that data was
taken to understand the demands/requirements of precision shooting of hardcast
bullets from Marlin Microgroove barrels in the CAS velocity range
(900-1300 fps); the data one will find on these Additional Data
Pages is chronograph data which does not fit into the CAS data class,
but is sufficiently interesting to make worth sharing.
As stated on the LeverGun Studies/Data pages, and will be restated here: the data published on this site: is chronograph data - we are simply reporting: what we did, with what, and what we saw as the results. In no way is this data being shared as reloading data.
The resulting data is listed by cartridge. Data within a cartridge is broken down by bullet weight and type. The context information for a cartridge and information about the history/lineage of a cartridge can be had by clicking on the cartridge name at the left. To access the data for a particular bullet weight/type, click on that title as listed under the desired cartridge.
The acronyms used in the tables for the different cartridge components are:
PR : Primer,
|It is expressly and strictly the handloader's responsibility
to know their firearms, reloading equipment, components, procedures and safety practices. |
GMDR has no control over individual reloading practices, reloading components or the quality of the firearms in which the resulting ammunition will be used, and as such, assumes NO liability for mishaps of any kind resulting from the use or misuse of the engineering data presented on these pages.
Click on a cartridge title at the left to see information about that cartridge and the specific context
information for that cartridge's data; Click on the bullet weight listed beneath each cartridge to see the data
for that cartridge/bullet weight.
