Same is true for 9mm. For example, a couple of my loads are a 100gr hard cast bullet at 1450 fps, and a 180gr hard cast at 900 fps. Both have similar meplat size and are cast from the same alloy. The 100gr load will punch through 1/4" aluminum plate easily and blow up a couple water jugs on the back side, while the 180 gr won't make it through the plate at all, or several layers of thinner sheet metal. On the other hand, the 180gr penetrates a long way in soft media, much further than the 100gr fast bullet.
Thank you Sir for this info
My own preferred loads in 9mm are the various 147 grain bullets. My concerns are different than most here. When doing paid bird counts I frequently end up in close proximity to feral hogs in locations where they are not hunted or shot, and consequently display a reduced fear of humans. At the same time, accessing randomly assigned count points often has me pushing through dense cover. Numerous times I have flushed resting hogs at close range, they do not seem to react to the sound of my approach pushing through the brush and undercover.
In the past 30 years only ever had a problem with one; a large boar that was reluctant to yield the path.
At the same time going armed is frowned upon by the employer, so I go concealed carry, preferred handgun at present is a Springfield Armory XDs (cap. 9+1).
In the brush I carry Buffalo Bore 147gr lead solids, everywhere else similar velocity hollowpoints. If I ever am jumped by a hog, hopefully ten rounds of them Buffalo Bores at point blank range will get it done.
