Recommended Posts

EMG Open Hybrid 4 Popples 38SC

Recoil Spring: 8V lbs Wolff

Mainspring: 17 lbs

Bullet: 125 gr Zero Bullets JHP Conical 136

Brass: Starline

Primer: CCI 400/500

Powder: 9.6 gr VV3N38

OAL: 1.225-1.227"

Velocity: 1,388 fps

PF: 173.575

Groups: 0.75-1.00" @ 7-10 yards standing unsupported

 

Warning Note:  Loads can be different in every gun/barrel combination.  Remember to start 10% off if not more, and work your load up.

 

Intent of this post is reference and get an idea of what other shooters are doing.  Specially since it it's hard to get components.

The Zero conical bullets are extremely good bullets I am running the the same springs brass primers and powder as you do only 8.9 3n38 with PF of 170.000 in my 4 port hybrid MCG gun. Shoots very flat with a modified Sprinco.

I tried VV3N38 9.0 gr, 169 PF...gun shot well.

 

Powder: 9.0 gr VV3N38

OAL: 1.225-1.227"

Velocity: 1,350 fps

PF: 168.750

 

In the end, I will probably settled with 9.3-9.4 gr to stay at 172PF.
