The Clay Cartridge Range: - Note our Cartridges quote actual speeds to CIP protocols unlike most UK cartridges so they are probably faster than what you use.

The Best of the Best - The M Competition Range

The M competition range has been designed without compromise. These Cartridges use only the best components available to produce the Ultimate loads. They all feature the Recoil Reducing 8 Star crimp exclusive to Mary Arm. 5% antimony shot in all the range. Nickel coated shot in three of the range to produce the best patterns possible at longer ranges. All speed matched so you can change seamlessly between any of the range and not notice any difference.

Richard Atkins test result: "The laboratory report reveals are very respectable set of results with a velocity level above the ‘magic’ figure of 400m/s. That is seriously quick; fortunately the recoil I felt in the restricted time available for me to shoot these particular cartridges did not reflect this and I found the CYRANO quite comfortable to shoot. For closer targets, which BIOR cartridges are usually used for, opening up the chokes could be a good idea too. I would have like more time with the BIOR but the results here speak for themselves."
