Why No High S.D .22 bullets?

More Weight = Higher Sectional Density

To illustrate higher sectional density bullets with a .224" diameter see below:

Bullet Weight versus Sectional Density

1. 100 grains = 0.285
2. 125 grains = 0.356
3. 150 grains = 0.427
4. 175 grains = 0.498
5. 200 grains = 0.569

Sure, a 200gr. bullet with a .224" diameter has what appears to be a great SD number but which case do you plan on seating down into?

The higher SD bullets would have their place in a sub-sonic/supressed application, but that "seating depth" thing would keep raising it's ugly head - perhaps in a specialty cartridge, etc.

Too, with the extremely long bullet for the caliber, the rifle's rate of twist would have to be tightened up for some stability.
