The Recommended Load thead for the Miha 9mm 125gn HP mold

[Dannix]

This thread was created for the Miha 9mm 125gn HP mold Group Buy (http://castboolits.gunloads.com/showthread.php?t=126682) boolit. Please share your favorite loads as you have opportunity.

[buyobuyo]

My load is:

Mixed cases
Rem or Win primers
50/50 WW/PB + tin for 1.5% total
Water dropped and sized to 0.357"
4.0gr Unique
COAL ???? (I'll check after work)

Chronos at around 1050 fps.

COAL ???? (I'll check after work)
Hey, could you look this up when you have a moment? Thanks!

[buyobuyo]

My COAL is 1.085".

[CPL Lou]

So far my favorite load has been:

5.6 grains HS-6
CCI 500 Primers
Either the hollow point or penta pin bullets (haven't tried it as a solid)
Cast of 50% WW and 50% pure with 2% tin added
Sized to .358"
Winchester cases (left over from firing WW white box ammo)
Lars' 2500 + lube
C.O.L = 1.130"

My COL may seem a bit long, but they run fine in my pistol without any problems.
I shoot these out of my SIG P225 and get zero leading and great accuracy @ 25 yards.

I also plan on trying out loads using Unique, Blue Dot and AA 5.
I have to wait until I get more use of my right arm and more feeling in my left hand 1st though. It seems my TBI and MS have conspired to temporarily (hopefully) take me out of action. [smilie=b:

All the other data will remain the same as to cases, primers, etc.

I'll have to dig out my old chrony, camera and some gallon water jugs while I am at it.
Might as well do it right ! :smile:

I load alot of 9s with 3.6 grains of aa2.

[Jeff Michel]

3.5 grains of Bullseye, 50/50 lube, sized .358 in a .38 Spl. In a 77/357 Ruger. Quarter sized groups at 50 Yds.

[4719dave]

tag ,got 1k casted was cking load data to load em up . just buit a 9mm ar .

[45 2.1]

50/50 WW/Pb water dropped with 5.4 gr. of Russian Unique in the 9mm Largo. Mr. opposum never knew what hit him.

[Rusty W]

Here's one I use. I think oal was 1.10, water dropped wheel weight, lube was carnuba red, sized to .358. I tried several different powders, 231, universal, unique, bullseye, hs6, all leaded the barrel some less than others, then I tried 4756 and the load shown. All came together, the hi-point carbine really shoots this combo.

50/50 WW/Pb water dropped
Interesting. I wouldn't have thought of water dropping 50/50. I'm going to have to give that a go.


That's a nice looking group with your HiPoint, Rusty. That's the sort of group I'm going to see if I can achieve with this boolit, but in my Glock. We'll see. Here's my benchmark (http://www.brianenos.com/forums/index.php?showtopic=89264&view=findpost&p=1416711), with Precision Delta JRNs.

Here's BeeMan's post on the group buy thread. Thanks for posting, BeeMan.

Someone PM'd for the data on my 9mm load. Since 9mm can be troublesome I'm posting a detailed response here hoping it helps someone else. The usual caveats apply about this report representing only my results, your results may vary, work up safely, etc.

- Win brass, expanded with a custom m-die to ensure the .3585 bullet is not sized down after seating.
- Fed 100 primer
- 4.5 grains WSF, which is a mid range load per the Hodgdon load data center for a lead bullet
- Miha 359-125 with round HP pins, air cooled wheel weights
- Tumble lubed twice with 45/45/10, once before push through sizing to .3585, and again after sizing
- Seated to 1.100 OAL, with a taper crimp that just straightens the bell on the case.

Accurate to the limits of my ability. Zero leading after 50 rounds. A little powder and lube residue pushed out with a single patch of Eds Red and a couple dry patches. Feeding was flawless.

Two comments:
- Fit is king. Sizing .3585 just allows the loaded cartridge to chamber. The custom m-die made this possible, though others have used 38 special expanders, etc.
- Powder burn rate seems touchier in the 9mm than in other cartridges. WSF burns slow enough to avoid stripping while using ACWW. A fast burn to bump up is not needed when bullet fit is correct.

My preferred load giving much better accuracy than I ever achieved with jacketed or plated bullets

Geco cases
Magtech primers
Water dropped range scrap
BAC Lube
Sized to 0.358"
4.2gr VV N340
COAL 1.085"

Chronos at 1050 fps from a Smith & Wesson M&P9

[Dannix]

Did you simply choose an OAL that worked for your barrel and then just worked up the powder charge until you found accuracy or ran into a guestimated fps limit?

I'm just curious since the only VV 9mm loads I can find always have a COAL of 1.142".

Thanks. I just got in a pound of N340 to try, so we'll see how I fare.

Geco cases
Magtech primers
Water dropped range scrap
BAC Lube
Sized to 0.358"
4.2gr VV N340
COAL 1.085"

[wrench]

My latest combination is:
Mihec bullet sized .358" cast from 50/50 Clipon WW and soft, air cooled.
lotac or BAC lube
mixed range brass
I've used Wolf, Winchester, and CCI primers
4.5g WSF
OAL 1.115"

Shoots really well in my STI Spartan, and a couple of Glocks (Shhhhhhh)
I tried tumble lubing with 45/45/10, and got some leading, may try that again now that I have my sizing issues figured out.

[Beerd]

old thread but given the popularity of this bullet I'll bump it.

water dropped wheel weight
Felix lube
sized .357
misc. range brass
Win sm pistol primer
1.085" oal
4.4 gr Unique OR 4.0 gr Red Dot
..

[bangerjim]

Shooting 3.6gn of ETR7 with the slug cast at ~11Bhn + PC (both ESPC and BBDT).

Excellent accuracy out of my M1-9mm carbine.

His 6 banger 9mm NLG mold is another BIG winner in my book also!!!!!!

Here are light loads that have worked well for me with this bullet in 9mm:
2.9 grains Clays
3.5-3.7 grains W231/HP38
4.0 grains Universal
4.4 grains Unique

One of the best uses for this bullet is in re-creating the Federal Nyclad .38 Special 125-grain load. Cast of soft alloy and loaded over a max load of W231, I got excellent accuracy and decent expansion through denim shooting a S&W 442 snubby.

What COAL for these loads did you use?

[RobsTV]

50/50 + tin, air cooled 11-13 BHN, Round HP pin, sized .358..

Springfield XDm 3.8", or any 9mm, including carbines.
Cast as above
Using Lee S&W 38 PTE plug (SE1699) to keep 9mm brass fat.
5.05gr WAP (Ramshot Silhouette), OAL = 1.110.
Chrono's at 1040fps

38spl revolvers
same cast and size as above.
4.7gr W231, OAL = 1.510
Chrono's at 885fps

357 mag, 3" SS J-Frame
Same cast as above, but added PB G/C.
15.4gr A4100 (Ramshot Enforcer), OAL = 1.640
Chrono's at 1512fps

357 mag, 3" SS J-Frame
Same cast as above, no G/C
5.7gr w231, OAL 1.640,
no Chrono data yet.

All above shooting for best group size at 10 yards. Most final results were a ragged hole.

[Low Budget Shooter]

JLamot2020, for 9mm I set the case mouth in the middle of the front driving band. For .38, I crimped just over the front driving band. Hope that helps. LBS

Not quite the answer I expected, but yea it works.

[wonderwolf]

Shot a combat pistol match today with 4.0gr of red dot and this bullet with penta pin. Also did a lobotomy on a ground hog and later skinned her out in search of the slug. Really juiced the brain and skull but couldn't find the pill as it was somewhere further south and I didn't feel like going that far. Did get some wet pack testing in today as well as chrono, chrono says they are going about 1025 fps

[Pine Baron]

This recipe looks like a winner. I'm always looking for Red dot recipes. Gonna try this in my Hi Point Carbine. Thanks Beerd!

[Beerd]

Sure thing.
And welcome to Cast Boolits!

[ipijohn]

The penta version of this mold is my fav for 9mm powder coated over 4.2 grn of 231. Chrono is 1050 out of my 4 inch semi auto pistols and 1250 out of my 995.

[Low Budget Shooter]

Wonderwolf, that is cast bullet perfection!!!

[Elkins45]

Favorite load? In the 9mm, or 38 special , or 357 magnum, or 357 sig? :)

It's a versatile bullet.

[Rattlesnake Charlie]

I see a couple of guys using 4.0 gr of Red Dot. This is probably my favorite 9mm load. Makes powder go a long ways. Clean burning. Good accuracy in all 9mm's I've tried it in.

[slasher]

I know this is an old thread but wondering if there is any new info out there.
Looking specifically for data on a Glock 19 with W231. Thinking starting load would be around 3.6gr up to maybe 4.4gr but wasn't sure about OAL since I can't find much for 135gr hollow point/flat nose. 135gr is about what all of mine weigh from this 359-125 HP mold and I'm using the equivalent of Lyman#2.
Thanks

[dougader]

I've been using W231 for 30-some years. If I were you, I'd start with that 3.6 grain load and work up slowly from there, being very careful with anything over about 4.1 grains with your 135 grain bullet.

If you find you're needing higher velocity, switch to a slower powder like Unique, AA5, VV 3n37 or N350, Ramshot Silhouette...

[rintinglen]

I have used a fair few of these loaded with 4.0 WW.231, WSP, OAL 1.10". This is not a barn burner, but my BHP and Sig P-6 both like it. I have yet to try it in my smaller 9 MM's.

[Mr.Pink]

Hi just started with reloading and casting. I bought the mp 359-125-HP 4 cav and want to load it for 9mm luger in my FN Hi Power. But I can only get my hands on vihtavuori N320 Powder. Anyone got experience with it i cant seem to find any load data with lead bullets from them only Copper Plated. Or should i just take the grains and take the next best weight bullet withloading data.

Or should I just take the grains and take the next best weight bullet with loading data.

I'D EXPECT the same data available for copper plated projectiles to work for cast lead projectiles, also. If anything, velocities might be slightly higher, since cast lead bullets tend to have greater lubricity than copper-plated or jacketed projectiles. When in doubt, try data from the next heavier bullet weight and work up.

[Mr.Pink]

Thanks will do
