If the back end of the teamer has been spec'd to work with Lapua 243 cases, life will really be good for you. F-forming with a top end charge of fast-ish powder for the standard 243W, the bullets firmly into the lands (.020 past the 'just touching' point) and cases very lightly oiled with 3-In-1 or something similar will give you great cases on the first firing.

For load data with a F-formed case, start with top end loads for the standard 243W or, as 'Stick mentioned, hop to the 6MM Remington standard case and go from there.

Good shootin'. -Al

Thanks for the constructive advice!
