I am using hybrid 100v in a 6mm ai with 87 vmaxs. Barrel is a 8 twist but has shot the 87s well. Not sure on velocity no chronographWhat powder are you guy`s using for the 6 x 284 launching the 87 Vmax bullet???
I`m interested in the velocity achieved as well......
Thinking this might be an alternative to the 6mm AI......
