Went through about 150 rounds with the 9mm S&W and switched over to the Rossi model 68.
First shot sounded real lite. Hmmm! Real odd ..... OK...... STOP..... Unload the cylinder and check.
I can see light though the barrel. No obstructions. That was odd!
Lets reload and try again. Second shot was like a cap gun, just a little pop and no recoil. Alright then!!! something is not right. Unload the cylinder and check.
125.7 grains? no wonder!!!
NOTE: For those not familiar with reloading the it seems counter intuitive to use a less propellant for a heavier projectile, but you have to think of it in terms of maximum allowable pressure in the firearm. See the right hand column in the above image. A lighter projectile offers less resistance than does a heavier one, thus the pressure is less if you use the same amount of propellant as you would for a heavier one. So for lighter projectiles we use a heavier propellant charge or you have the results I experienced here. Also to consider is whether the bullet is cast lead or jacketed as they offer different resistance and this result in different pressures, even if they are the same weight and use same charge of propellant.
