A bullet mold for review



I received a two-cavity .45 caliber mold from MP Molds several weeks ago to try out and review. It came packaged with a top punch for the bullet as well as two different inserts to cast different style cavities for the hollow point.







The two different inserts for forming the cavity on the bullet.



The mold did not ship with handles as MP does not build handles but recommends the Lee six-cavity mold handles. I called Midway USA and placed an order for a set of handles.

This particular mold throws two styles of a 200-grain hollow point bullet and a flat point round nose bullet





Using wheel weights rendered into one-pound ingots I cast over 200 bullets using the two different inserts. The first hollow point with the smooth cavity averaged 200.9 grains while the second hollow point averaged 202.6 grains. One feature of this mold that I particularly liked is you can invert the insert that forms the cavity in the bullet and it will act as the bottom of the mold allowing you to cast a round nose flat point bullet that averaged 213 grains (before it is sized).



After casting I spent the next couple of hours resizing and lubing the bullets in prep for loading. Once all were finished I loaded them using 5.6 grains of Unique and Winchester primers. Cases were mostly Winchester but mixed headstamps were included.

After some experimenting with the seater die I settled on a measurement of 1.250” for the overall length. That measurement agreed with my go-no-go gauge.

Waking up in of anticipation a nice day at the range trying out this new bullet I was disappointed it was pouring rain. I had to wait another two weeks to try them out.

My friend Clint and I set out early Sunday morning bound for the pistol range.

For testing I used my Colt 1991A1 and Gold Cup Trophy, both of which are mostly factory original (the changes to the 1991A1 are a reduced-radius firing pin stop, Colt steel trigger, Colt arched mainspring housing, and iridium front sight. The Gold Cup Trophy has a one piece full length guide rod and a TechWellUSA magazine well.) None of the changes affect reliability. Magazines used were Check-Mate seven round dimpled follower hybrid lip, Tripp Research Cobra mag, and a few old GI style magazines.



Reliability was 100% with no failures. All three styles of the cast bullet fed smoothly and averaged two inch groups shot offhand at thirty to forty feet.
As a base line I had loaded about 100 200grain lead semi-wadcutters (cast from Lyman mold 452630 my go to load for range/match use). Both bullets performed the same out of both pistols so that tells me that the new MP bullet performed as well as my favorite bullet.
I also ran a few through my Ruger New Model Blackhawk with the .45 automatic cylinder in place.
I did not use any other platform to test the bullets only because honestly I do not own any other semi automatic pistol that is not a Government Model.
All bullet styles performed well as far as feed and function goes.
I will admit casting is not for everyone as it does require time set aside to produce a number of bullets for reloading.
The benefit is great reduction in bullet cost in this case (as well as being able to produce bullets that are not readily available).

This and many more styles of bullet molds are available from MP Molds.

MSRP is €72 (which is roughly $104 US)

Thank you Miha at MP Molds for giving me the chance to review this fine mold.
