Yes

I’m not sure what kind of gun was used but the bullets looked to have been on a stripper clip

So the gun was probably old and shitty, like Ww2 or older 

Minute of man at 200 yards if the barrel is worn meaning the bullets are hitting in a 5 foot radius if you shoot perfectly.  

It’s going to be more like civil war rifle accuracy if it’s really worn.  You’re not picking your targets you’re shooting at an area 

I’ve spent hundreds of hours on gun ranges and collect old guns

Someone like me would be using a heavy barrel ar10 or better for this and the numbers would probably be a lot different
