Thread: .243 subsonic loads Tikka M55

The 90gr eld-x works well for me, doing 3140fps. The Sierra 85 hpbt and Hornady 87 sp shoot well too, as does the Sierra prohunter 100gr.
I haven’t tried subs in the 243. In the 308 a full load of trailboss is about 15gr, subsonic is 7.5gr in the 1:12 twist and 8gr in the 1:8 twist using Robert’s 151gr cast bullets, I think he does a 6mm cast as well (shooternz on the forum).
