Tinker-

I'll type up the info I have when I get home (i'm away from home at the moment). My understanding (From what I've read) was that it was named for a gent during WWII I believe who liked to launch projectiles from tanks at ridiculous speeds.

But I'll see if I can't get it typed up for you.....according to my data (A-Square Reloading manual) the only bullet weight they have is a 118 gr solid bullet....but they're launching it ....really....really ...fast...I think the powder charges I saw listed were around 140gr etc. launching somewhere near 5000fps........yea

Back on this later
