Well I'm tired of 777 pellets and having to swab after every shot. I'm going to try BH209 for the first time. I'm confused about the measurements. I've read that VOLUME in GRAINS BH209 X 0.667 = WEIGHT in GRAINS BH209 so I'm assuming that if I used 2 777 pellets I would use 66.7 of BH209. Is this correct? I'm using a TC Triumph with 250 GR TC Shockwave Super Slides.

Thanks
