With a 26" browning 300 win using win brass and 215 primers I was getting 2920 fps with either the 200 gr sierra or 200 grain nosler partition using 71.5 grains rl22 for the fuel. To answer more directly, I'd say between 2800 and 2900 fps depanding on whether you have a "fast" rifle or not; some guns just develop a bit more speed with a load than the next one and a chrono will get you closer than my crystal ball will.
I've gone to 165's only in my 300 win as it'll do 3250-3300 fps with them, but the 200 can be a good way to play if you don't have a 300 rum to toss 180 gr+ bullets like I do.
