Go to Speer bullets website. They show the 33 gr but no data for that bullet, may be new. Usually you can contact/e-mail them and they will give you the data for their bullet.
I myself would probably use close to what I use for 30,35,&36 gr bullets. Factory told me I could use their 30 gr V.G. in 223 and 22-250 but don't know how they'd fly in the 250, FAST? May try it someday but I like a heavier bullet in the 250 and some 223s.
