I know there's bound to be some "sperts" here regarding this cartridge so what I'm asking is for some info regarding this cartridge and it's performance factors. Loads, ballistics data, best action (in your opinion) for building one up, barrel lengths and contours, etc.? I've received some data from a computer friend a year or so ago from up Pennsylvania way...the good fellow even sent me a video of some stuff and my 64 year old mine has had a "brain fart" and as I saved his info....my PC "crashed" a while back and I lost the data! Believe the last name was Gessell...or something akin to that! Need your help please! Thanks!
