I prefer to use jump insensitive bullets. When Bergers first came out in 223, miraculous claims were made by the shooters making outstanding scores with the things. Then, a match or two down the road, the shooters who were previously Bergers were using something else. Bergers were jump sensitive, with a little throat erosion, the groups got big.
I can say that my 168 SMK’s and 175 SMK’s are jump insensitive and I can use them set to the same setting depth in every rifle and they will shoot well. I have had great luck with 68 SMK’s in the 223. I do not like seating bullets on the lands, or too near the lands. If you ever shot at Camp Perry, at some time during the 600 yard match, some boater gets in the impact area. Then everyone on the firing line has to empty their rifle, stick in their OBI, and wait till the authorities chase the fisherman away. I have found, as have others, that a bullet jammed in the throat has a tendency to stay there if the cartridge is not fired. Sometimes the case will come out, spilling lots of powder in the mechanism, and you have to find someone with a cleaning rod to knock the bullet out of the throat.
