I have a CZ 527 carbine with a 18 inch barrel and was concerned the Federal premium with 60 grain partition wouls stabilize in the short barrel and slow(1 in 12 twist)I shot the rifle up to 150 yards and the load shot less than 2 inches at 150 with a 2 power heavy duplex scope ! This makes me believe that this load would satbilize in a longer barrel with faster twist.I have no experience with the Winchester load you speak of. I have never used the load on any game animal as I just got the rifle a few months ago and our hunting season is long over But there are quite a few threads that mention the 60 grain partition for Game animals and it has good reports. Look for 223 ammo for deer,223 for deer in either a search or in the forums them selves and perhaps you can find more info on this. Craig
