Why not use +p
How about because a standard pressure loading is more controllable
A lot of cops carry target wadcutters in their J-frames because they can empty the weapon faster and more accurately than when it is loaded with +p ammo. And those wadcutters actually perform almost as good as the better +p loads....better if you value hitting the target quickly, accurately and repeatedly
Kudos to them, since they actually practice with their carry load....all the time
I see lots of people that carry +p or +p+ but they practice with the cheapest wimpiest target ammo they can find.( and they call it training)
Heaven help them when they suddenly need to defend themselves and their weapon of choice is suddenly much harder to control
The better performing loads in the major calibers are most all standard pressure. While there are +p loads that do just as good....why bother going to +p for the same performance
By sticking to RA9T and RA45T for carry, I can easily practice with the same type of FMJ and see the same POI as my carry load
All without breaking the bank (or my pistol)
38 spcl is the one loading where +p is still required to get good expansion/penetration
in some loads
10 - 15 years ago bullet design was not all that scientific...in order to get good expansion and penetration many/most loads relied upon increased velocity to perform....especially from short barrels
Currently the only rounds that still need to be +p to function are the "boutique" rounds like EFMJ and Powerball
That and some of the lighter bullets....if you don't have the mass then you need the velocity
Times have changed and progress has been made
Why not take advantage of it?
(Besides ...I have seen a fair amount of testing that showed several brands of +p ammo actually tested out to lower pressure and velocity than standard loads..but at higher prices)
