180’s all day.
I have experienced less flip with the 180’s in my Glocks, 35,23,27. The heavier slugs should penetrate deeper.
Interesting.
The power factor of the 155gr load is 209, the 180gr load is 189 - a measurement of relative momentum. But the sectional density of the 155gr is .138 versus the 180gr's .160 - not sure what the relative penetration would be given the velocity difference. I've never seen this tested.
I wonder if the softer alloy of the 180gr matters much?
Btw, the SD of a 147gr 9mm bullet is .166 - (what Phil used), yet the momentum of that load is only 150, which shows how little work was required to get that bullet deep into his bear.
