Still good penetration at 3500 yards....!

Not sure the accuracy is on par with a 338 Lapua, but the penetration and TKO are significantly better.

Well, I do have to say that was interesting.

[AJMD429]

I don't know the velocity, but multiply that in feet per second times 119, and that would be the Taylor Knockout Factor (already taken into account the weight of 98,000 grains, and diameter of 8.5 inches). If it is 1,000 fps it would have a TKO of 119,000.......!

If you assume θ=45° (for near-maximum range), and y=0 (impact site, level ground) and x=10,580 feet, you should be able to get a value for 'initial velocity'.

Since that equation ignores air friction, you'd really be deriving an average velocity, so you'd have to know something to use as a ballistic coefficient to get more precise. I'd think that at subsonic velocities that projectile would have a pretty high b.c.....

Now, let's attach some homemade rocket motors to the bowling balls

Something just not right about lighting a fuse from the business end!!
It'll go wrong one day!

Yeah that's spooky....

That was my first thought, too! The whole thing looks like a bad idea.

Having some experience firing solid shot and grape from real cannons i found the entire video somewhat unnerving.

Bubba, I'm fixin' to light this here fuse, crack us a couple more cold ones. No sweat, the ole lady ain't gonna need this here ball till Thursday evening.

This https://youtu.be/NbsLxJUNr8M is the least of the worries I'd think (hit neighbors barn).

Unsure why they don't drill a fuse-hole somewhere....

A fuse hole seems to be a rather good idea.

Who needs penetration when the blunt force trauma will kill them.

That did seem just a bit sketchy, but it sounds like he has a lot of experience with his gun.
I have watched the bowling ball mortar guys play, and mercy sakes when that old ball starts on the downside of the parabola, the wind in the finger holes makes an ungodly screeching sound.
I have a letter written by my great-grandfather's brother to their little sister back home in Wisconsin from "outside Atlanta with Sherman" during the Civil War, and he describes the racket made by the anything-we-can-find junk being fired in desperation by Confederate artillery.

I hope no one is foolish enough to be in the impact area ather being warned.
