    As every mold i have purchased from MP its excellent machining. Quality hardware that i not not have to search around to find replacements. Very consistant cavity to cavity.
    Love the hollow point pins on every other MP mold i have purchased (about 10 so far) .
    This one for subsonic 300 blackout could use some longer pins for better expansion.

    As always, the mold is top notch, and works great.

    The time before I got this mold (part of a group buy) was REALLY long but the mold itself is a work of art.

    Excellent quality molds and fast shipping, but have not used them yet. I am sure they will cast as great as they look and others have stated and yes Brass is heavy compared to Al. I don’t expect as many constant hours do to weight but I can swap to Al molds when tired to keep casting.
    Great Job MP.

    Everything went excellent from ordering all the way to delivery. MP Molds showed “best in class” performance by good order information status after ordering and a very quick transport to Sweden. I have not tested the mold yet, but I have assembled it with the hollow point pins. This is my first mold. The quality of the mold block looks very good and I really look forward to test it. One thing that I noticed after assembly is that 2 of 3 hollow point pins seems to jam a little bit in the guide holes. 1 of the hollow point pins ejects perfect. Lubricating did not solve it. This might be an adjustment issue, otherwise I will ask MP Mold staff for help. I am very pleased with MP Molds so far! I like their innovative design with multiple mold options. Keep up the good work! // PH
