Which one will penetrate further? Assuming they weigh the same and have the same power.
Common sense tells me that a non-expanding bullet would have more penetration than an expanding one - all things equal.
Or is it a trick question?
FMJ will penetrate deeper as a general rule.
The FMJ makes a smaller frontal area during penetratio. It will always penetrate further than an expanding bullet.
FMJ bullets all else being equal.
At the serious risk of
Of the two, a FMJ and a JHP of the same caliber, having equal mass (and equal sectional density for that matter) and equal velocity, assuming that the JHP expands (even nominally), the FMJ will have a greater depth of penetration.
This assumes that both projectiles encounter the same media and obstructions, all else being equal. Of course, that is rarely the case.
