Saw an add on a TV hunting show. They had a new 7mm factory cartridge, super fast, no belt, anyone have any info on it. Seems like it might be the 300 short necked down??

There are now two 7mm Ultra Cartridges, the 7mm Ultra Short mag and the & mm Ultra mag.

The big one is just the 300 ultra necked down, I guess you are suppose to beaat STW velocities by 100 fps or so. The Ultra SA in made for a short action, there has been alot of press on it lately.

I like the new 7 ultra. Probably because I like big cases with small little bullets. I have an stw but I wont be surprised if an ultra ends up in the cabinet sooner or later. The ultra is the .300 necked to 7mm and has a little bit more capacity than the stw. Both the ultra and the stw are pretty overbore so barrel life is not very long. My ruger #1 7mm stw wears a 26 inch tube but since its a single shot its the same length as a 22 inch barreled bolt gun. Means I can throw a 30 inch barrel on it and have the same length as a rem 700 in 7 ultra. Velocities from a 30 inch stw will be higher than the 26 inch barreled 7 ultra. Wonderful isn't it. Get a #1 with a 30 inch tube in 7 ultra and you will have a superfast 7mm and not to mention a hell of a long range rifle. It will have the same energy figures as a large magnum .30 and it will have a flatter trajectory. And it wont be too big to tote around in the field. I can hear it calling to me now!! The pronghorn are already getting nervous!!
