New 12ga MP Mold

[Helka]

Just received this yesterday. Did 3 heat cycles before casting last night. Made about 200.

Shooting them on Friday will report back

Looks good. Are they 525gr like the Lyman?

 

[Helka]

yes but with my recipe they are dropping just shy of 500

That is a SWEET looking jumbo pellet mold!!

Looking great.

Are most guys using these with wads or going with the fullbore one?

 

[Helka]

I'll be using a wad to try, new to shotgun reloading, have lots to learn

Looks identical to my lyman ouput.

I use wad cups when using smokeless. I load brass shells with BP and use fiber wads.

Fantastic mold and slug for the DIY guy. Shoots awesome outta everything I feed it thru. Not a real long range projectile but 100 yrds and maybe stretched out a little more.

That's some nice groups, hoping for that tomorrow when i try them out. Are your just wax tumbled or PC or bare

 

[smokeeter]

filled the hollow base with wax. check out castboolits, some guys are filling the bases with hot glue. Helps tighten up the groups. Slugs are just as they come out of the mold.

I will certainly try that. Any specific wax?

 

[smokeeter]

I just shave paraffin wax into a spoon and melt it with a burning candle under the spoon then pour into the base , after it solidifies, I trim with a knife. Melting a candle and letting the dripping fill the base will also work but it takes too long.

Thanks

Nice job. What are you shooting these out of ? Smooth bore, rifled barrel, open sights, or scope ?

Dickinson XX2T smooth bore open site on a rest at 25yrds

What is your recipe & where did you get it? I’ve been shooting Lyman slugs for several years and their data shows 23.0gr Unique with their 525gr slug. Accuracy is pretty good at 50 yards (2 1/2”) from an 870. Sabot slugs are wonderfully accurate but who can afford $4-$5 each time you touch the trigger? Best of luck.

I got the recipe from Lyman reloading manual. It does say to do 23 grains of unique but I’m a weakling for full power so I purposely did a lighter load. I still need to do a work up. I’m so new to reloading for shotgun I almost need a mentor lmao.

I’m old & not a big guy, the 23 gr load (to me) is milder than a trap load. Not trying to get you to go there right now, just saying.
