partitions just arent accurate in my gun either, but ive shot 117gr sierra spitzer, 117gr Hornady Interlock, 120gr HPBT sierra, 110gr accubonds, and 120gr nosler solid base boattail trying to find a bigger and better bullet than the 100gr NBT. All shot better than the partition, my gun just didnt like them. Of the big bullets the old 120gr Nosler Solid Base Boattail shot the best. They shot as good as the ballistic tips and accubonds. I read somewhere that they are the ballistic tips with a soft point. I would shoot the accubonds but I just cant see giving 50 cents a piece for those things when they dont shoot any better or kill any deader than the solid base. I dont think they make them anymore but Ive got about 600 of them
