7mm Backcountry pfft

[UnckleBob]

30-06 in a SA cartridge already exists, it's called the .30 Thompson Center. Nobody cared, it's most notable now for being the parent case of 6.5cdm.

The 30TC cannot achieve 30-06 velocities out of a 16" barrel.

The magic of the 7BC is not velocity. It about replacing a 7RM velocities from a 24" barrel with 7RM velocities from a 16-18" barrel.
