I was specifically asking about the 169gr vs a 175 TMK, not SMK as the TMK does have a much better BC and holds it at lower velocities much better. I THINK, the tipped version is longer than the 175 SMK, so I was wondering how those two stack up to each other.
169 smk. .527bc, 1.310 oal (@2180fps^)
177 smk. .540bc, 1.xxx oal (@1700fps^)
168 tmk. .536bc, 1.357 oal (@2050fps^)
175 tmk. .545bc, 1.384 oal (@2400fps^)
175 smk. .496bc, 1.235 oal (@2600fps)
Any of those running 2600, 2650, beat the 175smk.
I have no experience with the 177 smk.
I wanted 2700/2750, and found pressure with the 168 and 175 TMK and 175 SMK at 2.800 mag length, so, I made friends with the 169.
I wanted one round for all distance to avoid changing bullet weight/speed/pressure in places that didn't allow sighters to be able to harmonically settle the barrel w different bullet, and the 169 provided that, for me. And kept my learning curve simpler, one of my goals for less stress in a match.
Hope this helps.
