I use molly so can't comment on the carbon. I am finding is slower though. An extra 2" of barrel and an extra .2gn of powder to get the same velocities I've been running for 3 years now. It also weighs different. It's hard to explain but its like the kernals are a tiny bit lighter.

Found quite the opposite. Need 0.3gr less with the newer stuff I have. I guess still need to buy large quantities in a batch and re test when changing batches.

You will have to use heavier bullet than a 110gr vmax then!
