All,

Thank you for your replies.

Whilst 12.7x99mm is not at this time subject to legal restriction, I am concerned that it may be vulnerable to political expediency.

I am therefore interested in a cartridge with a lower profile.

The advantage of using the same projectiles is very significant and therefore the basis for not considering the 14.5 x 114mm cartridge.

Whilst I could always seek help from Bertram, I'd like to see what else may be available as a source of brass.

Any other pointers would be wonderful.

Cheers,
