When it came to balancing working pressure and case capacity against bullet selection the .307 Winchester is the leader – obsolete but still the leader.
Here are two poor pictures to discuss seating depth, cannalure placement and meplat diameter.
From left to right the Hornady 160-grain FTX, 170-grain Hornady Interlock, 170-grain Speer Hot Cor and the Nosler 170-grain round nose Partition.
Note the position of the cannalure on the Nosler Partition. This bullet requires deep seating in the 307 Winchester.
The 160-grain Hornady FTX also requires rather deep seating. The FTX bullet also requires shortening the case length.
The Speer and the Hornady bullets have the cannalures pretty close to one another.
The Hornady bullet has a wide meplat as I tried to illustrate in the second picture. This requires seating the bullet slightly deeper in the 307 Winchester case as the ball seat and abrupt origin to the rifling will not allow the use of the cannalure in my rifle without an interfierence fit when chambering the cartridge.
When you are using appropriate burn rate powders you begin to run out of case capacity just as you are reaching maximum velocity. You will find yourself balancing seating depth with powder charge.
