8x33 & 8x57 Semi Auto/Full Auto Reloading

Update

Well, I found the perfect solution with cast bullets,

The .325 sizer worked. good groups, flawless functioning. So to recap, the NEI bullet mold 94, 32 cal gas checks, 19 grains of IMR4227.


Well, the next challenge will be reloading for the MG42

Over a thousand rounds with lead cast bullets

Well, I have put over a thousand rounds of the lead cast through my MP44. They function great, accuracy still just Ok.

I had some lead build up on the piston part of the Oprod. It cleaned off easily. However, I am considering having a spare Oprod teflon coated?

I am not happy with the crimp from crimp/seating die from hornady, I would like to get a separate crimp die for the fourth slot in my Dillion 550b. Any suggestions on how to crimp8x33?

Thanks Pat
 
I'm using an 8x57 LEE factory crimp die. You need to machine a 24mm tall cartridge riser to get the 8x33 cartridge into the crimper. In your case, you could chose a cartridge riser height that puts the crimp right where your preferred groove is located.
 
8mm Kurz crimp

Thanks, that may not work for me. I want to put the crimp die on the last stage of my Dillion 550B. I had my gunsmith ream out the Dillion 7.62x39 powder funnel for 7.92x33 so that I could crank out 8mm kurz like it was 9mm. I want one bullet per pull on the handle. I do not want to have separate setup for crimping.

I was thinking about two options, not sure what is best?

1. Cut down a Lee 8x57 crimp die or...
2. Have my smith ream out a Lee 7.62x39 crimp die?

Lee 8x33 Crimp Die

Crimp problem solved, I just ordered an 8x33 custom factory crimp die from Lee.

Not sure how I missed this before with my searches?

Got the Lee 8x33 Crimp Die

It took a few minutes to get it adjusted on my Dillion. Note, it has to be the lowest die in a multistage set up. The shell holder pushes the inner part of the die upward into the sleeve causing the crimp to tighten.

I had to readjust the other three dies (sizing, powder, seating) to get all to work as they should.

It produces a nice factory crimp on my lead cast loads.

I also shot 150 grain Speer Pointed Soft reloads with 18.8 grains of IMR4227. Functioning and accuracy was fine, no signs of pressure.

This is good to know. I was wondering if somebody had a load for 150 grain bullets. How was the recoil?

Does anybody have a good load for a 7.92x57 using a 196 grain bullet?

I made 20 rounds using Hornady Match grade 196 grain BTHP #3237 using 42 grains of IMR 4064.

And 20 rounds using the same bullet and 43 grains of IMR4064. Neither load is worth a crap. I got shotgun patterns all over the paper. Both loads were seated at 3.250. Recoil was harsh.

On the other hand I also had on hand today some 150 grain soft point bullets loaded with 50 grains of IMR4350 that all grouped nicely at 100 yards.

But if anyone knows of a good load for the 196 grain bullets, please share.
 
Update on leadcast

I shot the PTR44 and MP44 today with handloads with both hornady and lead cast.

With 19.6 grains of IMR4227. The hornady are amazingly accurate in both the MP and PTR. The leadcast, well they function well on full auto. I just can not get any accuracy out of the leadcast. I give up,

I have tried everything, My leadcast will just be for full auto blasting. Not sure what I will do when my hornady 125 grains run out. Maybe, I will go to 150 grains?

Pat, 150 grain Hornady is now equally hard to find. I don't like Speer or Sierra because their 150 gr bullets don't have a cannelure for crimping.

I've been shooting a lot of the cast lead using 21.5 gr. of W680 in FNM cases. It's said to be the same as AA1680. I find that the bullets need to be quite hard even with the hi tech coating and using checks.
Straight linotype gives me decent groups. I tried block type mixed 1/3 type/2/3 soft lead. They shoot fairly decent but not as good as the linotype. I need to try an equal mix of type/lead since I have a fair amount of the type and lead.
Straight type might be ok but it takes more effort than I think it should to run them thru the sizer.
None shoot as accurately as the Hornadies though.

125 .323 Hornady

Well, I am getting low on 125 Jacketed bullets for relaoding. I have one box of 125 HP and two of the older pointed soft 125s'. So, 300 rounds. I also have two hundred rounds of Speer 150s' and a big supply of lead cast.

Maybe something will break loose, like Prvi selling 124 .323 bullets?

Any one ever imported Bullets for reloading

I see the Prvi bullets available for less than $20 a hundred on the German Websites. I tried to interpret the ATF guidance and I am still not sure. It looked like you needed an FFL and a Form 6? Does anyone have the requirements?

It seems like they count just the bullet the same as an round?

Any thoughts on how to get some Prvi Bullets for reloading?

Pat


I contacted Claus Espeholt in Denmark about component availability in Europe. He informed me that Prvi has just the bullets available for reloading under item number B-424. This item number shows up on www.eguns.de, the fleabay of guns in Germany. However, there are all kinds of paperwork involved in importing them to this country. Good news on that front though! Prvi Partizan has a direct USA distributor--

I have already emailed them inquiring about the possibility of ordering this item for sale in the USA. I informed them that I currently have 754 empties that are cleaned and resized just waiting for primers, powder, and bullets and that I would purchase 5000 if they could get them in for us. And that with the number of Mkb-42/MP43/MP44/STG44/PTR-44/K98 shooters currently in this country that shoot this round, plus the new BD-44's coming later this year, via El-Be-Tac and Robinson Armaments, I thought that they could easily sell at least 500K or even 1 million if they made them available to us.

The thing to remember about the difference between the Hornaday 125grs and the Prvi 123grs is that the Hornady does NOT have the cannelure for crimping like a military round while the Prvi does have the cannelure.

So, my suggestion/request is that everyone starting sending emails to everyone that you know who shoots this cartridge and have them start contacting TR&Z at the email address above and request that they make this bullet available to us for reloading.

Hi-Tek lube for Cast bullets

I tried the Hi-Tek lube on some 125 Grain Lead cast bullets in both the PTR44 and my MP44. The results in the PTR44 were great. They were as accurate as factory in the PTR! Accuracy in the MP44 was extremely poor! I used a .325 sizing die, I will try the .323 sizing die and see if that works for the MP44?

My buddy loaded 30 Cal Hi-Tek rounds for his belt fed 1919, it worked like a charm. When I get my MG42 return spring back from rebuild, i will try some.

Update on MP44, PTR44 Lead Cast Reloading

An update on relaoding, I went from the .325 down to the .323 sizing die with the Hi-Tek Bullets. I also went down from 19.6 Grains down to 17.6 Grains of IMR 4227. The Bullets with gas check and Hi-Tek Coating weigh in at about 144 Grains.

Accuracy in the MP44 improved dramatically. I am not sure if it was the smaller sizing die or the reduced load? The MP44 was also flawless in full auto with the reduced load. The PTR44 was also accurate and functioned well with this load.

Thanks Pete for letting me know about the Hi-Tek coating,

Pat
 
Might be able to convince a good friend of mine, who happens to be the VP of one of those LARGE bullet manufacturing groups to do a small run of 125gr 8mm HPBT, we were talking and he mentioned they were going to tool for 8mm here coming up and if I wanted he would trim it down to 125 for a few thousand. Would anyone be interested in that?

You should ask him if the bullets will have a cannelure for crimping. I don't like smooth bullets like the ones offered by Speer or Sierra. Semi autos with short/steep feed ramps exert a lot of pressure on the bullets while they are sliding up the feed ramp. Sometimes hard enough to push the bullets down the neck. For that reason my preferred bullets have been Hornady 3231 for MP44 and 3232 for G43.

I'm thinking your bullets must be quite a bit softer than mine . The soft ones will not shoot well at all if you push them fast. Likely why you see improved accuracy having dropped 2 grains.
The bullets I cast from linotype only weigh about 128 gr. HiTech coated and checked. I size .324. Loading 18 gr. IMR4227 they go about 1900 fps. That's in reworked .308 cases though that are heavier wall so my 18 gr. is not comparable to what you are loading. FNM cases weigh about 125gr. where my reworked ones weigh around 155gr.and give more bullet pull than the FNM.
Gateway Bullets not going to be selling the coating powder anymore I just found out. They are still in the coated bullet business just not selling powder by itself. I did get some of the black from them though as a kind of closeout. It sure makes for a good looking round with the black contrasting the brass. Was using the red/copper. Hope the black works as well.

Asking?

Will do, anything else I should ask him?

Why not a run of a couple hundred thou?
I think Graffs is selling the Hornady HP's now. they called me maybe 6 weeks ago about 5K I had on backorder. I cancelled when they said they were .30 or so now.
I have some of the Privi bullets on backorder now so I would assume they will be getting them before too long.
Thinking they are priced about what the Hornadys were a couple years ago.

Anyone have more current info re bullets from Graff?
Pete
