My throating dummies used a 160 Partition, base of bullet to base of neck;the 175 Partition seats slightly deeper into the case.Both bullets shoot well,and BTW have essentially the same POI to 600 yards, despite the velocity differences (3075 vs 3175-3200).Can't recall precise OAL, but know both are a bit over 3.5;close to 3.6.My rifle has an Echols box.
This is handy but raises a conundrum of sorts, in that,I am having a hard time finding a reason to use anything other than the 175 in this cartridge...
There may be hunting chores that a 175 Partition at almost 3100 can't do,but I bet the count is not very high.....if the thoughts of keeping things rock-stupid simple appeals,this might be a way to go.
