Tested 4 different .223 factory loads the other day, in order the rifle preferred (5 shots @ 120yds):
Winchester Ballistic Silvertip 55gr - 0.5” group
Federal Powershok 55gr - 1” group
Sako Gamehead 55gr - 2”+ group
Hornaday Superformance GMX 55gr - all over the place
The rifle is a CZ 527 and the barrel was allowed to cool between shots. For use on Roe deer (in Scotland) wanted to know what people are using and how effective they have found them to be. Obviously the rifle likes the Winchesters but concerned about this bullet on Roe. The Gameheads are the only one advertised as being suitable for deer.
