9mm Buffalo Bore 147gr +p vs G9 124gr +p woodsmen for Predator defense?

Seems like $100 worth of ammo would answer a lot of your questions

100% on the training and fundamentals.

My curiosity is more about the ammo itself.

Is the step up in recoil with the 147’s of a +p or +p+ variety and the greater penetration that should come with it worth it over possibly getting off one or two more shots with a lighter 115? In a charging predator situation.

Also wondering what the difference in penetration is between a 115 FMJ FP and say a 147 hard cast from 9mm?

There are numerous sources that show it's almost indistinguishable to determine not only the caliber, but also the round used on a victim between 9 mm, 38, 45, and 10 mm using standard ammunition for the respective caliber. Regarding penetration, a 124 non +p 9mm can have better penetration than a .45 using 180 grains; just like a 223 can versus a 308 given a shorter distance. However 308 will hit harder and have more mass and kinetic energy. Both kill just fine.

Here's a great read that should answer a lot of your questions:

An FMJ, or non-expanding bullet will penetrate further. Comparing a flat nose and standard FMJ of the same weight, the standard FMJ will likely penetrate further. Regarding damage overall, it will likely be less.

In actuality to answer your question, you're talking about less than an eighth to a 16th of an inch when looking at wound cavity in a small caliber.

There's a larger difference between a 147 and a 147 +p vs a 115 and 147 non P variant. In a subcompact, your hand will feel it. The 115+p Will be snappier than the 147 standard. +P+ is almost never recommended in polymer and/or subcompacts due to material fatigue of the firearm (nearly all manufacturers with polymer grips put this in bold in the user manual for that reason). It also gets extremely hot and you'll notice it'll be far more difficult to shoot follow up rounds.

It's why I don't take subcompacts with barrels smaller than 3.5 in in the field. Velocity is your friend with smaller calibers. There will be a noticeable difference of around 50 to 100 ft per second with the heavier grain bullets. I'll conceal carry all day with them, but I prefer to have a slightly heavier firearm with better muzzle control due to weight and length.



Hope this helps.

That’s probably what will happen.

Comparing a flat nose and standard FMJ of the same weight, the standard FMJ will likely penetrate further. Regarding damage overall, it will likely be less.

Flat points, especially with a wider meplat of around 60% of caliber, penetrate further and straighter - round-nose tend to yaw and not go as deep.

Yes, you're correct. I should have proof read what I wrote. They tend to carry much better aerodynamics as well.

Thank you for the correction.
