I have been working on larger size 6.8spcII ammo for a while, I have a 130gr load already now I have a 150gr load. I started with a 22.5 gr charge of H335, it functioned so I made 5 rounds of 23.0gr and 5 rounds at 23.5gr. They shot OK so I moved up to 24.0gr of H335 with RP brass and CCI#34 primers ,Coal 2.281" to 2.290" . 35 rounds to shoot next time out.
