I shoot the 124gr CPHP's with Titegroup and CCI 500's, here's my load data.
Bullet: Campro 124gr CPHP
Powder: TiteGroup
Primer: CCI 500
Charge Weight: 4.3gr
Trim Length: 0.750"
Overall Length: 1.095"
Shots: 10
Avg Velocity: 1128
Min Velocity: 1110
Max Velocity: 1139
Spread: 29
Std. Dev: 9
Temp: 85degF
The average velocity was nearly identical to a log of Factory Winchester 124gr FMJ's I had, but my SD's were way lower! 5.0gr of CFEPistol with the same setup will net you similar velocity, but slightly higher SD's. Both have been 100% reliable in my Glocks.
