I see your attempt at derailing the thread, but the fact is - yes that is correct, other than the fact there is no .223 75gr TSX to compare with your 40gr Vmax. Assuming you mean the 70gr TSX though - yes, a 40gr at higher velocity will punch through thicker steel (or aluminum) plate than a slower 70-75gr bullet. That is the opposite of what they do in meat where the heavier bullet usually can penetrate better.

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 cool

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.

Spot on! It seems that most do not realize that it takes speed to penetrate steel. A 55 grain varmint bullet at 3600 FPS will penetrate completely through 3/8" steel st 50 yards a 240 grain at 1400 FOS from a 44 will not, yet on a pig the 44 will penetrate deeper

I prefer and carry the lighter faster 9mm loads for my own use, but for what you describe, sounds like heavy solids are the way to go. Good example how one guy's needs are different than others.

What is a "paid bird count" though? I'm not familiar with that term.

Exactly that, where one is paid under contract to go out and count and or census birds present and/or in certain cases evaluate the habitat. Paid for by environmental consultants, , non-profits or varying levels of government entities. Nowhere near close enough to make a living, but like free money to a guy like me.

Lots of people are hobbyist bird watchers but it can be surprisingly hard to find a relative expert like myself who will also scrupulously follow count and data reporting protocols.

Or keep close company with feral hogs 🙂

You get a reputation for delivering what you said you would. I get a call or two most years, dunno how much longer I’ll have the ears for it tho.
