imr 8208 & sierra 65gr GK in 223

8202 xbr powder I'm pretty sure it's made by ADI in Aus we call it Benchmark 8208 they list starting 21 grn's and the max 23.8 grn's 52900psi for 69 grn Sierria HPBT. There other is 63 grn Sierria SP start 21 grn's and max 23.1 grn's 52400 psi.
Just email Hodgdon's to make sure.
 
I use 8208 xbr with both my R 700 VSSF and AR15 23.0 to 23.5 with 69 grain nosler CC It is very simalar to Benchmark easy to meter and shoots real well.
