22BR with 8208-XBR powder

[jefats]

Would like to begin load testing with 8208-XBR but can't find any data. Rifle is 1x8 twist and bullets from 50 grain on up.

Any help will be greatly appreciated.
Thanks
Jim

my 12 twist 22 BR gets about 3500 fps shooting 52 fowlers and 30.5 gr of 8208 XBR , seated .020 thous into lands. increasing the charge opened the group. 30.5 gr of benchmark did about the same.
