I load 180 PT,s accubonds and SGK,s ..015 to .025 off the lands. I have a rem. 700 BDL. I would say .174 is way too much jump and very well could cause bad accuracy. You would also be losing velocity as you increase bullet jump. The 3.340 is usually used for clip fed rifles which normally will not accept a longer length. My coal. is usually from 3.565 to 3.600 depending on the bullet. Loading down to 3.340 is usually a bad idea for top loading bolt actions. Also loading 180,s that short eats up powder space. Not good either.
