    Hi guys just wondered if anyone on the forum has tested the .22 MP 5.52 molds and what the accuracy is like. So if anyone has indeed purchased these  could you let me know what the ballistic characteristics is like along with how accurate are they. Here is an image of the mold

    I have tried then in 8 guns and they worked great in half of them , Mine shoot best in  the unchoked barrel going 900 fps , but one of my guns shoots them fine in 25 caliber at 700s fps ,  they are heavy so you need energy to push them well , what barrel do you have or gun ?  LOU

    I have this as well, they do well at 50 and 100m from a lw unchoked poly.  Like JW said they are heavy 35.5gr or so, so youll need 50+ fpe to push them.  Over 60 is probably preferable.

    What I'm after is been able to make my own 22 rifle slugs like the 21g Nielson slugs they fire well and accurate. If I could get a mould like the ones they make would be ideal.

    Remember guys, there are 2 types of mp moulds. one in 5.52 and other in .223-.224. the larger ones are for Huben only. Dont mistake the huben ones for 5.52mm ones. 

    Mddoghutty, Nielsen slugs are made with swaging die. the moulds wont create .217 NSA style slugs
