Same effect as jumping of a diving board vs jumping off the Golden Gate Bridge.
I have heard that jumping off a high span bridge into water is like hitting concrete.

Yep. Same as a projectile. The faster it is going, the more energy it carries. The barrier pushes energy back into the object hitting it. In this case, causing fragmentation. There is a term for it, but I took physics 30 years ago.....
Curious about the “specialty ammo” remark. My 10.5 shorties cycle everything I throw at them just fine running suppressed. Am I missing something?
I'll say this about my gov profile 10.5" SBR; it's a shooter. That little f*k is accurate. Not 100% sure why (PSA barrel), but it is.
A buddy of mine shot it and said "I want one of these!". Then I explained the Federal and State requirements. Then he said "never mind".
I feel that, I shrugged off the whole NFA thing for the longest time, then I bought a can and now I'm waaaaaayyyyy down the rabbit hole.
I think it's 'the bullsh!t to benefit ratio'...I could be mistaken though...Yep. Same as a projectile. The faster it is going, the more energy it carries.

I completely agree with this. Some of the insane stuff I see trying to get these things over 29"... the juice is not always worth the squeeze.If you are having a 29in OAL parameter , might as well have more bbl length than a trick buttstock . More velocity , longer dwell time , etc .
I’m not sure you’re making your stance on terminal ballistics vs marksmanship in short range weapons clear. Maybe you should reiterate it a few more times.I think it's 'the bullsh!t to benefit ratio'...I could be mistaken though...
The slower the projectile goes, the more problems you will have with over-penetration. With M193 ammo, the projectile is moving so fast, it fragments easily when hitting a barrier because of the energy it carries. Same effect as jumping of a diving board vs jumping off the Golden Gate Bridge. Believe it or not, slower projectiles like pistol rounds, buckshot etc. are much more likely to go through multiple sheets of drywall.
Shorter barrel, less velocity.
They measure it with the stock collapsed or a brace removed. It used to be brace/stock fully extended was the OAL
Yeah, no. That's wildly inaccurate.
Slower projectiles like pistol rounds overpenetrate more because of where their kinetic energy comes from. Heavy rounds that move slow impart most of their force from their mass. Going through drywall reduces acceleration, but not mass, so they retain force pretty well.
5.56, on the other hand, uses very light rounds moving very quickly. Striking solid objects removes acceleration, which is where the bulk of their force comes from, which means a drastic reduction in force.
Increasing velocity increases overpenetration. Period.
Your golden gate bridge comparison is actually quite an apt comparison, but not in the way you thought it would be. Jumping off of a diving board, you can dive 9 or 10 feet down without swimming. People who have ended up in a dive off of the golden gate bridge go *significantly* deeper, and many have survived. There was a teenager a couple years ago that not only survived a dive, but was swimming back to shore when the coast guard picked him up.
This would be true if every bullet just ice picked through media and didn’t exhibit effects that vary based on velocity. The effect of impact velocity on the structural integrity (or lack thereof) of a projectile is technically separate from what you’re talking about in your post (parts of which I agree with), but pertinent to the conversation at hand.Increasing velocity increases overpenetration. Period.
Beat me to it.You missed one important aspect in your analysis, projectile construction.
Yeah, no. That's wildly inaccurate.
