RST shortage, and other 2-1/2" shell sources?

Because the length of push is longer it is often perceived as less than shorter duration loads when the recoil energy is the same. Recoil energy is of course not the same as, but related to , chamber pressure. Chamber pressures for all these loads is below SAAMI maximum.

Of these different brand cartridges, which produces the greatest foot pounds of recoil ?

1 oz payload at 1200 fps
