Re 15 in 22BR data

Hey guys,
I'm getting ready to start back up on my Zombie 22BR project.....Ive got some necks turned (thanks to LR for the help on the right tools on that).
I know there's not alot of data floating around for it. I've dabbled some with Benchmark but that was before I turned my necks and my ES weren't very good. I've turned my necks and will try to get a baseline for accuracy and velocity with Benchmark first. I've got sierra data from 6br website, but it doesn't show re15. Id like to try re15 in this case. It seems to work really well in my 6br. Seems from the burn rate charts it should be fine but I'm not sure where to start with charges on this powder. Anyone have any ideas or can point me in the right direction? Maybe there's a reason it's not listed?
I'll most likely be sticking with 50gr bullets and up as its a 9 twist barrel.
Thanks!

Keep in mind Norma 203B = RL15. A bit slow for 50g-55g.

BL-C2 data will be real close on a weight basis, W748 will be slightly slower.

Treat load data from RLNest with a big grain of salt and a suspicious mind.

Thanks....and thanks for the link. With the 9 twist Ill be able to shoot some of the heavier bullets so I could maybe try re15 with those....
