[QUOTE="DJ Fergus, post: 1760572, member: 93895"] What makes the new cartridges so appealing is they are set up for long heavies. I guess most people don't realize that the old 7mm rem mag was initially designed (1962) around long heavies of it's time, 175 grainers. With a 2.500 case length , a Sammi chamber for off the shelf 175gr factory ammo and a Remington 700 with a factory magazine box of 3.700" long: it's perfect for a handloader to run just about any long range bullet between 160-168 grains and still be able to seat long. Standard remington 9.25 twist is perfect for 160-168 grain bullets. Don't like the belts? Throw the brass away after three firings cause you can buy twice as much 7mm rem mag brass for nearly the same cost as the new improved magnum cases. I'm not saying I don't want a 7mm prc ,saum , wsm etc... because I would love to have those also, but the 7mm rem mag is cheap & easy on a handloader. And I've had great results with the 165 grain Sierra federal factory ammo as well as other factory ammo. 6.5 creedmoors usually likes 140 grainers in factory form 7mm rem mags usually likes 160 grainers in factory form.
