Hi Dave,

There are certainly some big cases out there that have been historically used in various events, most are wildcats originating from existing brass that is fire formed and necked up or down to match a custom reamer.

I believe the 30 Boo Boo was developed by Dave Tooley in the USA to take advantage of the great quality RWS 8x68 brass that was available.

The Yogi and equivalents (.338 lapua variants) are now not allowed to be shot at most ranges.

All other modified cases are simply done for accuracy, and best not to focus (or talk online) about case capacity and Bang etc..... as they are just target rounds searching for accuracy and do not necessarily have more energy than any other standard 30 cal round if you get my point !

Les has a couple of nice (accurate) Heavy Gun calibres worth a look when you next see him.

Great topic to discuss in person over an ale at the next event though.

Cheers,

Anthony
