If you gun groups the 200gr SW good with 150 gr and you sight in 3 inches high at 100 then it will be about 4 inches low at two hundred yds. The BC is .269 and with 3 Pyrodex pellets in mine it chronys 2250 to 2350 min and max on 20 shots most are right about 2300 the SD on a 40 cal 200 gr is about or a little better than a 300 gr 45 if your gun likes it it really is a triffic load. There were some reports by some people on another page of getting moose with them. I have used them my Omega is one of the guns that will shoot tight groups with them at 150 gr and I have take both deer and boar with them. Lee
