Ammo question
Ok, this may sound stupid, but I have never really understood the difference between .38 Special and .38 Special +P. I have had only a limited amount of experience with a .38 Special for starters. I guess I just need to know what the difference between the two is, does +P have to be shot through a "special" type of .38 revolver and can I shoot +P through a .357 revolver?
Thanks!
Thanks!

Let me see, how to put the question. Is it true, that if you use one type of ammo for target, and a different ammo to hunt with that the weight should be the same For instance!! If you use 158 grain lead nose to practice with then you should use 158 grain jhp to hunt with. Is this correct? Seems to make sense, since both weights are equal so you should hit target in the same place, taken into consideration windage and elevation. Thank you for any information. 0 -
The energy in ft/lbs that the bullet has, as it exits the muzzle. More enrgy=more recoil, but also more "stopping" power.

THE HIGHER THE FOOT POUNDS OF ENERGY THE BETTER!
EXPLANATION: A 1,000 LB CAR GOING 60MPH HAS APX. 88,000 FTLBS OF ENERGY - MY CALCULATIONS MY BE WRONG, BUT I THINK YOU CAN GET THE JEST OF WHAT FOOT LBS OF ENERGY IS ABOUT.0 -

If I remember my physics right, the formula for kinetic energy
is ke=1/2MV^2 One half Mass times Velocity squared.
This is usually calculated with Kilograms and Meter per second.
In this case you get Foot Pounds because of the units of measurement.
Kinetic energy is the energy required to stop the bullet or projectile.
The formula means that higher velocity matters more that bullet weight
in producing energy. Muzzle Energy is a function of both the
weight of the bullet and its' muzzle velocity, It is a good measure
of power because it takes into account both important factors.
Heavier bullets supposedly have a higher stopping power. The 45 auto only has about 450 ft.lbs but it is best for stopping power because of the big heavy blunt bullet.
The new extremely high velocity, light bullets, operate on the
idea that the bullet is so light it will disintgrate upon impact(give up all its' energy) and not penetrate as much as the heavier bullet.
Anyway, the higher the energy the better, but bullet weight and design are important considerations as well.
There are special bullets that are designed with powder materials or non-lead that are almost guaranteed to expand immediately. Very high velocity, high muzzle energy, Expensive but very effective.
Sorry for all the info.

FT-LB is the stored energy of the projectile (bullet). On good ballistic reports you will find this rating for different distances from the muzzle. For self protection, only concern yourself with up to 50 feet. The higher the better. Penetration is an issue also. The FBI testing states that the ideal protection load should penetrate 12". I wouldn't accept under 6" as acceptable.
Well armed and well trained...the fundimentals of the 2nd ammendment!!0
