Germans greatly extending the range and effectiveness of their artillery. A big HE round too! I also saw some South Africans (?) that made a special chamber and throat to shoot a .22 LR and a .22 WMR but squeezing the bullet to exit as a .177”. Very interesting! I’d prefer a WMR to try as I dislike scraping lead from bores. Most cartridges are designed to prevent ignorant mistakes like that. The .270’s moved shoulder and .450 Marlin’s w/wide belt are two that come to mind.

Just as WB says, they do get longer when sizing down.

I remember reading in P.O. Ackley's writings.

About rechambering a 6.5 Arisaka to 30-06. When fired, the bullet would swage down and pass through the .264" bore.

Not sure if Ackley conducted the experiment or just wrote about it.

They managed to blow the barrel off the gun, but the action was undamaged. They cleaned the threads, screwed on a new barrel and continued to use the gun.

Some of these guys are blessed with bigger ones than I have or smaller brains. In fact, maybe both?

Even those guys who pioneered "Improved" rounds were gutsy.

WB and I get bashed regularly, but aren't even in the same zip code as these guys.

Realize this one was probably accidental, but...

Mr. Ackley did a LOT of experimenting

especially in the kind of stuff that hardly anyone today would even think of doing. He was a real pioneer in ballistics.

somebody putting a .45LC cylinder in a .44 mag Super Blackhawk and shooting .45LC through it.

Ha! He did not have the experience Ackley had ..
