[QUOTE="ken snyder, post: 622781, member: 26019"] Improved cartridges that have been enlarged for more powder capacity do shoot higher velocities most of the time but not all of the time and very often will not shoot as high a velocity with its lighter bullets than a smaller cartridge of the same caliber. The Pegasus uses basically a beltless 378 cartridge and gets over 3500 fps on a lot shorter barrel with a bullet that is not known in reloading data as a higher velocity manufacturer. The 500 A-Square is an interesting example It is a little more powerful than the 500 Jeffery (75 fps faster with a 65 grain heavier bullet) I don't think that I will find too many cartridges bases off of a 500 A Square because they have the 460 as a parent cartridge. so I am still lost as to why a 500 Jeffery is of any advantage. What can be improved on over other existing cartridges. The 500 Jeffery certainly doesn't have any edge in and in the example above a loss over what many of us already have sitting in our vaults as a parent cartridge. Don't get too google eyed over a head stamp and take it easy on pressure there is no magic but there are more than a few with life changing injuries. Friends do not let Friends shoot excessive pressures! [/QUOTE]
