Seeking to get feedback on success or lack thereof with Sierra 175gn in .280AI. I’m planning on experimenting with Sierra 175gn MK in my .280AI and was keen to ask if anyone had experience with the projectile in .280AI. I’m think That I’ll start with H4831SC at about 56.5gn the projectiles touching or -.002” back from lands. Will work back in -.005” increments from there in 5 shot groups. Looking to find a load that will be used 800yds out 1000yds F-open and possibly out to 1500 for other range Comps.
