The All New 6.5 Winchester Super Creedmoor Magnum (WSCM)
- SNN, Shooter's News Network

Sept 28, 2018 - Winchester announced today that it is releasing a new series of cartridges based on original engineering designs. The new Winchester Super Creedmoor Magnum (WSCM) cartridges will be unveiled at the SHOT Show early next year.

Not much is known about the new cartridges except that Winchester engineers have increased the size of all bullets, so they will match up with the word "super" in the name.

Pictured below is an old fashioned 6.5 Creedmoor beside the all new 6.5 Winchester Super Creedmoor Magnum (WSCM). Three things that limited the old Hornady Creedmoor design have been successfully addressed, according to a company spokesman.



The first improvement is redefining the 6.5 bullet. Traditional 6.5s are incapable of taking large game because of their small diameter. Starting next year, all 6.5mm bullets manufactured by Winchester will be 10mm in diameter. In other words, all 6.5mm bullets produced by Winchester will mic 10mm. 10mm is the new 6.5 millimeter. This change was a joint development with the European Union. The EU authorized a 50% increase in the size of the millimetre. It is unclear how this will affect US manufacturers, but companies in the US are expected to follow suit and increase bullet sizes by 50% to match the Europeans.

The new standard will improve killing power in the field.

The second improvement involves standardizing case shapes, making them bigger or smaller, to align with current designs. (See below). A new universal standard was tested and approved by the International Standards Organization. An ISO spokesman told SNN that standards work. Since the original Creedmoor cartridge was already accurate, making it bigger will make it more accurate, and also more accurate at longer ranges.

All future cartridges will conform to a simple standard. No rims. Power dependent on cartridge capacity. 25 degree shoulders.

Below are some of the new ISO approved cartridges. From left - the 4.35mm (6.5mm) Super Creedmoor Magnum Hornet, 5.56mm (8.35mm) Super Creedmoor Magnum Remington, 6.5mm (10mm) Winchester Super Creedmoor Magnum, 6.5mm (10mm) Super Nosler Creedmoor Magnum, 8.89mm (13.35mm) Super Remington Creedmoor Magnum.



The third development is a 10 year plan to convert all inch/US/UK cartridges over to metric. For example, by 2028, it will be illegal to sell or refer to a 30-06 as a 30-06. It must be referred to as the 7.62x63mm SCM (Super Creedmoor Magnum). With the approved 50% increase in millimetre size, the 7.62 becomes an 11.45mm, so the 30-06 will be renamed the 11.45x63mm Super Creedmoor Magnum.

The World Cartridge Organization (WCO) expects some initial resistance, but a special branch of the BATF is being formed to help with the conversions and prosecute any businesses or individuals who fail to comply.

A BATF spokesman said, "We are confident that US citizens will take to the new changes, especially those hunters and shooters from Texas. The 11.45x63mm Super Creedmoor Magnum sounds bigger and more powerful than the old fashioned 30-06. We're also happy that they decided to make all the bullet points red. Most of our agents thought it was a nice touch."
