Yo, what is up. this is mattv2099 and I have made 10mm shotshells this is the largest pistol caliber I own. and I want to see what happens when you shoot them out of a shotgun to be honest I don’t think there is enough mass and weight in there to make it go supersonic and make it penetrate anything. but we will give it a try so we have our door at forty feet. and the only round that’s been super accurate is the 7.62x54rmm I don’t expect this to do very well. it’s not very heavy. it’s just weird let’s see if we can hit what we are aiming at and let’s see how it goes through. good keyholing test that went wild. I don’t know where it hit. I have a camera zoomed in on it. bu tit totally went wild it hit the target. it didn’t deviate that far. but… who knows where it hit not where I was aiming. they’re pretty cool looking that’s for certain. let’s hit the rifleman magazine there. let’s see if it will even penetrate wow. that might have actually fully penetrated that was impressive. it did a lot more damage than I thought. we’ll check that out. after we shoot a couple more see if we can smoke that terra cotta pot this is a good accuracy test. it’s really hard for me to hit this with any other rounds that was super interesting. I was accurate and hit right where I aimed. but it didn’t go through and it didn’t damage the soda these could be more powerful than shooting them out of a Glock twenty this is more mass and could have more muzzle velocity it would be cool to chronograph these things let’s do the door one more time just to see if I can figure out where it’s hitting. I cannot tell. let’s survey the devastation. I’m looking. it’s possible it did not penetrate the door I was aiming there. and it went right and hit right there. bounced off. I cannot find the shells. I’m sure they’re obliterated. probably flew ten or fifteen feet away. they’re totally annihilated. we hit the terra cotta pot but there was not enough force to destroy the soda. that’s pretty cool appears good as new. here’s teh most interesting part. what does the bullet look like. let’s check our bullet trap here. we’ve got a bunch of NRA magazines taped together. and we will extract the 10mm round. first of all, it hit right there. you can see the 10mm sized hole. so here is the round. the bullet has been pushed up into it’s casing. it’s not brass. if it was brass. it would be more mishapen here’s what it looks like in here. shot cup comes down to there. thanks for watching.
