    Working up some light loads for my H&R 223. Need to go see how they do. Looking for 22 magnum performance.

    When I first looked at those rounds, the thought popped into my head... "it must be really cold in that room"

    Good luck, what powder you using? Since the bullet gr is so light I am guessing a heavy crimp or faster burning powder is going to be in order...

    Keep us posted...

    I did a few of those using 40 grain spitzers.
    Not enough power to cycle an AR, but on paper, they were supposed to be under 2000 fps.
    I thought I had written it down but I can't find my recipe anywhere.:(

    But it's doable.;)

    The Swedes did a lot of similar for 100 years or so with the 6.5X55mm.
    Little hollow cup bullet on left is the m/12. 9gr with mv of about 1673. The other two were heavier bullets and velocities I do not know right now. Used for training. Started with the m/12 and worked up by steps before full rounds were allowed.

    But, they used a very fast burning powder we do know.

    The bullet is not really that light. It's the C225-55-RF, otherwise known as the "22 Bator" . Named after the designer of the mold. .225 caliber, 55 grain, flat nosed, gas check. Its a fairly cylindrical found nose design with a lot of bearing surface. The mold was made by Lee and offered for sale by Midsouth Shooters Supply a few years ago.

    The bullets are seated deep to be just off the rifling. Any deeper and the bullet jams in the rifling when you close the action. They are powered by Unique powder, and they are not crimped. Velocity should be around 1800 fps.

    These were a good bullet in a 22 Hornet rifle I used to have, and we're intended for a wildcat that never came to be. They are good performers on small game and varmits.

    These are not intended to be able to cycle an MSR, they might, but I would be surprised if they even made enough gas. These are for my single shot Handi rifle.

    These have been made to work in an MSR though. In my case, these are to replicate the 22 Squirrel, a wildcat based on the 22 Hornet case, basically a shortened 22 K-Hornet. Here is a download showing the 22 Squirrel next to a 22 Magnum.
