I ordered 6.5 Creedmoor Sako Superhammerhead from MidwayUSA and got 6.5×55 SE. The interesting thing is how messed up the packaging is. It says 6.5×55 SE in three places but has a sticker that says 6.5 Creedmoor. I thought maybe that was just Midway messing it up but the end of the box says “6.5×55 SE 436H” and according to website 436H is the code for Creedmoor: https://www.sako.fi/en-us/cartridges/en-us-cartridges/super-hammerhead
Very weird. Check what you get if you buy any of this. Should have waited for Federal I guess…
