    Fantastic mold. Quite easy to cast with and shoots great at sub velocities in 300 BO. I will be trying it in 30-06 and .308 at higher velocity. Thanks for a great product.

    I’ve long waited for a bottle necked cartridge Bullet mold like this. One that is made to be powder coated and spoke of a need for one for several years on different cast Bullet forums. Glad to see MP has made such a mold and to my knowledge is the first.
    The bore riding area is undersized so that the powder coat makes up the difference in size. Then the drive bands are sized during the normal sizing operation.
    Most molds are from old designs that were made to use traditional lube and no allowance for the added dimension that the powder coat adds has been made to the mold. Using old mold designs and powder coating the bullets, resulted in a bullet that can only be partially corrected by sizing the bearing surface. While the bullet nose is left too big to chamber well. But MP has met the challenge and made such a mold.
    Hopefully MP will apply this idea to other bottle necked cartridge Bullet designs. I’d like to see this concept in lighter weight bullets for use at super sonic velocities. And in different calibers.
    I think the opportunities are endless.
    Though it this Bullet is made for the 300 Blackout, I wish there was a way in this review to show the 5 shot group size I was able to get with this Bullet in a 300 Win. Mag. Thanks again MP for the great mold and fast service.

    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

    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.
