Lapua 223 Remington Cases
The standard Lapua 223 Remington brass cases originally sold as reloading components were significantly heavier than Lake City cases and as such they had lower case capacities. Those cases were head-stamped:
LAPUA
.223 Rem.
These legacy Lapua cases produced higher muzzle velocities than the same load with Lake City cases along with an attendant increase in chamber pressure.
High Power Service Rifle shooters using heavy OTM bullets wanted all the case capacity they could get and therefore were not very interested in using the legacy Lapua cases. Lapua later introduced their “match” version of their hand-loading component brass which was significantly lighter and had more case capacity than the legacy cases and were roughly equivalent to Lake City brass. This is the brass that is head-stamped:
LAPUA
223 Rem MATCH
The Lapua match brass originally came in the boxes shown on the left and now comes in the plastic containers shown on the right . . .
Sadly, Laupua has been slowly increasing the weight of the match cases over the last several years and therefore decreasing the case capacity.
