AND the ctgs. also had large enough rims to lower breech thrust.





It's actually the other way around.
For any given pressure, breech thrust increases as the cartridge base diameter and area increases.

It's x pounds per square inch cartridge pressure acting on x square inch's of base area to produce x pounds of breech thrust.

The bigger case head diameter will have the bigger base area and the bigger breech thrust.





I've never been able to wrap my head around this...
