It seems the story behind these bullets is that Midway USA bought a truckload of 2nd bullets to be repackage and sold. Pictures I've looked at on the web for bullet comparisons appear closest to Winchester 7mm 150 gr.

Does anyone know what company originally made them?

What I do know is they indeed are 7mm and after individually weighing a dozen or so they come in at 150 grs + or - .1 grain or so. They have a very long 'nose' from the cannelure which is close to the ogive out to the tip. These seem like they were built for the 7mm mag. I shoot a 7mm-08 so using a load data for 150 gr. nosler and dropping the charge 5% below their minimum and working up, I shot a very nice group using 37.3 grain of RL15 with a COAL of 2.800".
