Well man, I hope you know that the 240grain .44 has a SD of .185 and the 230grain 10mm is at .205SD and looks to be a fine tool for the job for anyone. The 200grain 10mm is at .179SD which is more comparable to the 240grn .44 and should be more than fine for a deer, especially at 800+ ft lbs from a 6" bbl. The difference between .400 and .429 is pretty nil if we are talking hardcast. The penetration of either is more than enough for a deer.
