MP Molds Advice

[dannya1a]

i only use pure lead for my casting. tin does help but mainly with pellets. with my slugs i only use pure lead, no tin in the mix at all.

This was my first time to mold the slugs are not too bad but I faced two problems. 1: the rings around the slugs were not as good as should be they are very light rings on my slugs. 2: some slugs were having deep lines on the nose I shared the pictures before. Some mold user's told me to use tin in the mixture to expand the lead to get good rings on the slugs and some told me to increase the temperature of lead and mold to get better fill. I hope this will help me in next molding.

These have a better ballistic coefficient.

where did you get you mold for these? and what is the weight of them?

Hi there I am a new user of mp molds for 5.52mm I have some issues by molding. Why the some slugs have marks on them maybe something wrong with my molding way can you please suggest View attachment 42434View attachment 42439

Preheat your mold to 450 degrees. And, be sure to clean the mold well to remove the factory oils that may only surface after you heat it up a time or two. The 2 biggest culprits to what you're seeing, which is called "folding", are hot lead in a cold mold, and impurities/ contamination in your pour.

The 5.5 is for the Huben?

 

[EliteAirCustoms]

I'd be interested in the 5.52, maybe both if the price is right

Edguns too. I'm sure there are others.
Get the 5.55mm mold for the most versatility. I can size the 5.55mm (.2185) slug down to .2165.

Normal bores: .2165, .2169, .2173, .2177,

Oversized bores: .2185, .219, .220

Thanks, I see there a 5.58 as well. Not sure about that one. NSA sells an oversized 22 cal slug for the Huben. I believe it's .223

I see this slugs is .224. That's a pretty big slug. Does it come with a top punch? Take a lot of push/pull to size that down without deforming the pointed nose

There are a few different guns that use this slug. The die at MP is .2228. You can get the remainder of the sizing dies from lee. The entire spectrum for this barrel diameter for the least cost will be: .221, .222, .2228 (MP), .223, .224, and .225.

Noe sells sizing die, in just about every size

You are correct. However, I'm eyeing .219 & .220. They told me to check back late February/early March 2025 at the earliest for out of stock dies. Lee seems to always have their sizing dies in stock, and they ship out the next day.
