    Hey folks,

    Sorry I'm trying to reinvent the wheel here, but I am soon to receive my custom .243 Win (Kampfeld) with a 1:9 Krieger barrel.

    What is my ceiling on bullet weight?

    I'm thinking I can run 105 A-MAX bullets at best, but I'm probably going to play it safe with the 90 gr. moly scenar.

    Also, why can I push velocity more with moly than with the standard scenar?

    Is it a slickness issue? Does a clean pass mean less pressure?

    HELP!!

    Don't get me wrong...I'm a .5", one hole guy with several rifles...I just don't know a thing about the 243 or moly.
