      Beautiful looking molds. Looks to be great quality. Can’t wait to try.

    2. Chris G.

      Great product, excellent quality and delivered very fast

      My first MP Mold …first of what I think will be many. This mold is real quality. A bit heavier than Lee Mold so takes some getting used to but what a mold. It makes really nice sharp bullets.Heat retention is much better. I have used it twice and can see my improvements as it settles in. I made both 357 revolver and 9mm (sized them down to 356)with these bullets. Feed and shoot beautiful. Thank You MP!

    4. Jason

      Very high quality mold. and fast shipping. Drops beautiful 9mm hollow points, just open the mold and they fall right out. I did use a little lapping compound on the pins to make them move a little smoother. I also keep temps up to fill in the tips perfectly.

    6. Nicolas Sullivan

      Very happy with this mold , perfect bullets once you get her hot enough.

    7. Nickos Klementzos

      Cast very nice bullets. Drops from mold with no effort. Looking forward to buying a mold in .40 soon.

    8. Douglas k

      I use this mold for 9mm , no sizing lubed or powder coated , this is a accurate bullet and like all molds I have bought from MP they have been excellent and true pleasures to cast with , the mold block alignment pins are tapered and allow the blocks to close and open better then other brands , the heavy steel sprue plate has been true and precise on each mold , cast hollow point or solid and enjoy .

    9. Douglas k

      This is a great mold already have one but wanted one for a future gift , great 9mm bullet , I am powder coating and it fits in all my 9mm pistols , accurate and a hollow point .

      Good mold, easy to order & fast delivery.

    13. john lindvig

      used a hot plate for first drop. perfect. needed to use crocus cloth on several pins so they would slide. other that great. first time with a brass mold and had to learn to regulate the heat in the mold for easy releases. thumps up. !!!!

    14. Mike Moore

      Very satisfied with the hp .357 mold

    15. Tommy Buchmeyer

      Amazing shipping time beautiful mold

    16. Robert Binion

      I ordered my mould on a Monday and received it the next Monday evening.I cleaned it early Tuesday then heated head pot and mould and casting (20lb pot),977 bullets later refilled the potshot it down.Iculled 41 that did not suit me.Iamvery much satisfied with this mould, it got to fell a little heavy later into the casting due to my arthritis.It is not my favorite 9mm/38 mould but I can imagine it could become so.IfIcould give it a 6 star rating I would.

    17. Michael Rausch

      Absolutely beautiful mold.

    18. Mark Eldredge

      I have had nothing but great experience with MP molds they produce superior results when I use them. I have already got 2000 great bullets with the only problem coming from operator error. I will be getting a couple more in the near future. Great service and price, they are well made and thank you for getting me the pins I needed for my 40 S&W mold.
      Thank you!

    26. Billy T.

      Love this bullet shape.

    27. David Meszaros

      Very impressed by the quality of the mold, and pin design.

    28. Steven D Frasure

      Much better than any other bullet mold I’ve ever used, by a LOT and I have many types. Beautifully machined, casts perfect HP bullets that fall out 95% on their own, the remainder fall out with a gentle rap. Takes no time to turn out a lot of perfect HP’s.(4 cavity). Shipped same day i ordered online. Came to other side of the planet in 3 days. Had it in hand in a week. Packaged with everything to do 3 different nose types. This is an heirloom grade tool.

    29. Austin

      By far the best mold you can buy! Worth the price and shipping was fast to the US

      Great Bullet Mold!

    35. Christopher B.

      So far this mold has done incredibly well as all molds do it takes some getting used to it and I’m still working that curve but my initial results have been some very nice hollow points that are showing perfect expansion…they seat just like a FMJ and can be seated with the same COL unlike the LEE that have to be seated extremely deep to function properly. Overall I would recommend this mold.
      Even had a couple of the Cross pins that had damaged threads a couple of emails later and new ones are on their way now.

    36. Bill

      Being new to bullet casting I have no prior experience with bullet molds. Though I have loaded my own ammo for about 40 years now I find that the bullets from this mold is excellent. the 125gr. H/P bullet fired from my 6″ .357 magnum into ballistic gel opened up to 16.73MM!! loaded with 8.0 gr. unique powder giving me appx. 1260 f.p.s per my chrony. I believe as I reach my casting zen I will be making cast bullets far better than I could purchase. Happy with purchase.

    41. James B.

      I followed the instructions on the web site to run the mold through a few heat cycles and to lube it, and it worked great. It started producing good bullets very quickly.

    42. Javier P.

      Best quality I’ve ever seen in a bullet mold. Craftsmanship it’s outstanding and casts just as good as it looks. Can’t wait for the MP 227-65 GC Solid 6 Cavity Mold to be available. With out a doubt its next on my list.

    43. M Beck

      Best molds ever. Got item under a week from date of purchase for international shipping

    44. Brian H.

      I have come to the realization that I will only be buying MP molds in the future. The quality, is second to none, and I am already casting these by the pound. Do yourself a favor and make sure you get the 4 cavity, as you will want as many of these as you can have!

    50. jean louis

      superbe moule , du vrai travail d’orfèvre , usinage parfait et prix très correct les meilleurs moules selon moi.

    51. William

      This is an excellent mold and it does like the lead hot for complete fill out. I would definitely recommend this mild for anyone using 9mm.

    52. Daniel L.

      Fairly new to casting but I really enjoy using these brass HP molds over the aluminum ones I have.

    53. Michael

      The Mold is Beautiful, I haven’t used them yet but hope to pour soon

    54. Richard M.

      This is by far the best mold I have ever used. MP Mold’s service is also among the best, very prompt, very professional. I know I will be purchasing more MP Mold products in the future.

    55. JOHN F.

      Casted 40lbs of alloy with this mold so far. I could not be more pleased! I really like the fat lube grove and the HP shape. It is the perfect 9mm happy pill. Brass is way better than aluminum and steel imo. fast shipping! Will recommend and buy other MP-Molds in the future.

    56. David

      Arrived in a week with international shipping and was exactly as expected, would purchase from here again

      Fast delivery to Wisconsin and great product!!! Molds like a dream!!! This is my second mold and definitely thinking about another one. Keep up the good work!

    59. Eric G.

      I sure wish I’d discovered these molds first before spending money on others. They are simply the best.

      Support pins on hollow point already broke less than 100 bullets.

    61. Jeff Miller

      Very high quality

    62. Ronnie

      Cast up about 250 bullets with this mold over the weekend and as with all my other MP HP molds I have, it was a dream to cast with. If you want a HP mold, and have a great experience first time casting HP’s especially one that cast penta points in multiple cavities, do yourself a favor and use a MP mold, you won’t regret it.

    63. Gabriel S.

      Mold is great quality & produces excellent bullets in my opinion, I’m very happy with this product. Delivery was so extremely fast I was amazed, I couldn’t get a product shipped from the state next to mine as fast. I’m excited to place my next order from MP-Mold, thank you guys & please don’t change anything your doing.

    71. Andrew N.

      This was my first MP mold. It looks and feels like a quality product. It takes some used-to in comparison to Lee molds:
      1. Do not expect to heat up the mold by casting, it is not going to happen. Heat plate is needed.
      2. Alternate filling sequences – from back to forth and forth to back to avoid creation of “cold” areas.
      3. To release sticky bullets, hit the handler, not the mold
      4. Use copper wool to remove stubborn lead droplets from the brass surface
      5. Throughout the molding session, mallet hitting will cause pins’ screws to get loose, keep hex wrenches handy
      The only reason I gave 4 start is that pin and its connectors require fitting combination as some do not allow the pin to move freely under own weight. But this is a minor obstacle.
      Will buy more molds in the future.

      Five stars all the way! These molds are durable and well-made. They’ve exceeded my expectations in terms of performance and ease of use.

    78. RICHARD S.

      Almost as good as my MP .402-165 mold. The only thing I can complain about, is that I have to squeeze it together tighter than my other mold. If I don’t squeeze the handles harder, I get that seam on the sides, and a tiny “wire edge” overflow at the tip of the hollow point. It is easily scratched off with a fingernail (almost small enough to just be rubbed off), and does not affect the performance. I’m fairly new to casting, but my neighbor who has been doing it for over 40 years says these are the best molds he’s ever used. If you’re used to the older molds from other people, the temperature tends to need to be a little higher, and don’t forget to clean them well before using them. I also highly recommend using a pencil to graphite the tip of the hollow point pins. I’ve only cast a few hundred with this new mold, but it’s well built, and anticipate using it for the rest of my life. I have no doubt it will last thousands and thousands of rounds. Very well built, and worth every penny.

      I’ve been using MP hollow point bullet molds for several years, and I’m continually impressed by their precision and versatility. The molds produce consistent, high-quality bullets every time. Whether I’m reloading for target practice or hunting, these molds provide excellent performance and reliability.

    83. Ervin

      They sent the wrong mold. I ordered the 357-125 but they sent a 359-125. Will see how they handle this and update the review.

    84. Anonymous (verified owner)

      If you’re looking for reliable hollow point molds, this is it. Casting sessions go faster, bullets are consistent in weight, and accuracy at the range speaks for itself.
