Is H4895 good for jacketed x39?
I don't know. I don't see it in either of my Lyman books. I originally went with C.E. Harris article Practical Dope on the 7.62x39 and decided due to my manuals to try IMR4198. Accuracy was shit. @Jay77 had such good luck with 2400 in his sks and Harris also recommended it, I gave it a try. Good Accuracy but won't cycle the action and I am at the max. I will give anything a shot and RL-7 is in my books and indicted by Harris. I will research H4895 and see what is out there for loads. I have about 8 more manuals to dig thru. Do you have a starting load in mind? Thanks

I thought harris had a load with H4895 ?
 
That is a narrow range between starting and max loads, 27-28. This is for jacketed so i should start a bit less. A reduced load would be 16.8 but that probably wouldnt run the action either. If it doesnt work out, i can still use it for 308 and 8mm. If it is in stock at my local store, i will give it a try. thanks

Anything within safety is worth a try. I like the H4895 reduced loads in the larger 30 cal cases .
H4895 should work. It produces much more volume of gas than the faster powders like 2400, red dot and such.
You can do as harris does and up the hardness of your cast loads and up the powder charges.
I think he pushed sks/aka cast to 2000 fps?

Ok, first day casting bullets. RCBS cast iron mold and using straight clip on wheel weight material. Took a few drops to grt the mold up to temp but things stopped being wrinkly after that. The other thing I learned was to leave the lead in the mold for about 15 seconds before knocking off the sprue plate. The bullets seemed to be consistently better after that. Some look like the mold wasn’t fully closed and left a little seam of lead at the top. Anything else anyone see to help me? I didn’t grt any frosting as far as I could tell but I’m a noob. Should they fill out better? Maybe add a bit of tin?

Finally. Welcome to the club!

Ok so that flashing on some of the bullets could be the mould not totally closed. Usually a spec of lead stuck in between the mould faces. It also could be too hot a temp and too much tin which can cause the lead to flow into the vent lines. It’s hard to tell. It does look like there’s some spider webs to that flashing. Which also happens when the mould is help open by the spec of lead.

I wouldn’t bother with tin because the fill out looks awesome.

Keep doing what you’re doing and you’ll notice the little variations that occur when you cast hotter or cooler. Faster or slower.

Casting is all about cadence which you’re quickly figuring out.

Now time to size/lube/load/shoot.

Great! I can see now why people run two moulds at once.

The Star lubrisizer is ready to go for these 45s.

Thanks to all of you (as part of the Cast Bullet Seminar) for all the knowledge and assistance!

Yeah once you get it down (you’re there) then run 2 moulds to up your efficiency.

Then you need 2 lead furnaces. So when one dries up you can swap to the second and let the lead melt down in the first.

Maximum boolits!

Look good, dont worry to much about frosting.

What @38ExtraSpecial said plus your lead is too hot.
Looks great for a first try, seriously.
Come to the seminar and learn how to coat those.

I'm in Taunton if you need to size, lube or coat.

Thanks. That was 4.5 on the Lee 4-20. So, i’ll bump it down to 4 and see how it looks. An online resource said between 4 and 5. I don’t have a lead thermometer yet but will get one shortly for better measurements.

I was at the seminar last year and will be back again this year. It just took me forever to get started (mainly just assembling equipment).

Thermometer is a must. My Lee pots run completely different dial wise. They also start dropping lower. Someone on another forum explained how it works and how you can clean the contact points to get it back up to snuff but they won’t stay consistent as they get old and worn is the gist of it

Cheap thermocouple meter off Amazon is the easiest.
Lee pots will get hotter as the lead level drops so you need to keep an eye on it or not let it go below half.
 
Getting ready to load up these wheel weight bullets I made and I want to make sure I have this correct. This chart from Lee shows the amount of pressure that a particular alloy of lead can withstand, but I want to make double sure I am reading this right. Based on this, if we take the WW as 11 BHN (low end) that means I can have up to 15,000 PSI. From my load manuals, this means I can use Titegroup at 4.5 grains for 230 gn 45 ACP since the pressure is only 10,000 PSI, way under the 15,000. Correct?

You will probably find some of your best loads on the lower side of pressure anyway.
Bullet fit to throat/lead will be more of a factor. 45 acp for me has been very easy with very few issues.
 
I went to the range today with 93 of the 45 ACP loads. The cast was a 45-230-RN as previously described. I sized to .452 and lubed in my Star lubrasizer with Carnauba Red from WLL. I then loaded with 4.5 gns Titegroup to a COAL of 1.200.

All of the rounds went straight through the paper with no keyholing (at 10 yds). It was a little smoky but all the rounds fired and had no issues. At home, I borescoped the barrel and there was no leading in the barrel.

I’ll make up some more over the holiday and stretch the distance a bit to see if anything changes.

Crazy that even with 7 cent primers…it’s a 10 cent cartridge to make with cast.

Want some coated to see if it's the lube or the powder creating the excess smoke?

I'm going to get some Hi-Tek and start doing that in a little bit once I do some more casting and get that down a little better. Building a PID is the next step to ensure proper temp.

During the Cast Bullet Seminar, it would be helpful to get 20 or so to be able to test it out. Thank you very much for the offer.

Amazing how cheap it is to make good ammo right? Some disagree but we know they’re just stupid.

Probably the lube causing the smoke. All of that stuff is Smokey but I love the smell of anything with alox in it.

I don't care much about color so a $20 thermocouple meter and a Walmart toaster oven is all I use for hitek.
PM me an address and I'll fill a small flat rate with those bullets and some hitek powder
 
Yes
I went to silhouette because of leading with faster powders.
What are you sizing to?
.356, I want to say but I have a new batch to size and I might go .357. What I think is the problem might be slightly oversized bullets and some of the hi tek is coming off during sizing on a few. Small hiccup no biggy. Coating a bunch of .357 about 15 pounds give or take.
