7mm Backcountry pfft

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.

To say nobody cared ill bet is not quite accurate.

Nobody cared enough to be a guinea pig, I believe that.

Being pretty much only available in T/C rifles is a massive hindrance(not necessarily because T/C, but any cartridge only available from one manufacturer almost never does well).

308 is already commonly owned, known, and trusted.

thres an echo in here.

Ive been beating my head against this wall for months.

Yes. I too cannot comprehend the invention of a new straight wall cartridge when we already have the 45-70. But, then again I don't even shoot straight wall cartridges so maybe, perhaps, I don't understand the nuance because I don't use it.

Application based. There are still states that require straight wall cartridges to hunt deer, so there you have it. My state used to, thankfully we’re allowed centerfire now (on private land).
