Me and my reloading body, are trying to crack the nut about reloading, with homemade cast boolits.
We have soft lead (8 BHN), lead like Lyman no 2 (15BHN), Linotype (22 BHN) and pure tin. So we should be able to make the right lead mixture to cast from.
We powder coat, and make good boolits for 38spl og 357mag no problem.
We have a lot of different molds from MP, Lyman, Lee and no name. From 98grn up to 170grn all so we can size to cal . 357

But as many before os, we have trouble finding a boolit that can hit a sodacan at 25 yards, preferably with out tumbling.

Before any of you say it can not be done in a Glock, please read the next part.

At this time we reload whit this boolit.

Vitavauri 3N37 - 5.1grn and a small pistol primer from Magtech.
COL is 1.07"
And thay work. But we seem to fail to copy the results with home cast boolits.

Have any for cracked the code for loading home cast boolits for a stock Glock barrel?

Hope that answer is out there, and thanks for your time.
 
I haven't cast bullets for a Glock but I've fired a bunch of them! That is BEFORE I found out I couldn't do it!LOL!! I would think that slugging the barrel to find the proper diameter bullet would!d be a good start. If your Glock has Glocks funky rifling you might consider getting a drop in aftermarket barrel for it. Keep the barrel cleaned of any lead deposits. Maybe I was lucky but I ran lead for years in a couple Glocks with no problems. Use caution and accept this as coming from an old fart who still has all his fingers!!
 
I would also suggest a replacement barrel if possible. It may not be needed, but may make your path smoother and be a bit safer if you shoot a lot of lead. Not sure about there, but here (in normal times) they aren't too pricey.

I think that your sizing may be the issue. Sizing correctly for your 9mm may solve the issue. I'm not sure what a factory glock barrel tends to run but you may be sizing a bit small for it. Again, worth looking at a traditionally rifled barrel if you can get one as it may do fine with your .357 sizing (and would keep you from having 2 different sized bullets to work with). I am thinking the glock factory barrel may need a larger size.

You have many lead options. What hardness are you going with now?

I have loaded thousands of rounds of 9mm for my Glocks and never had any leading. I started out with straight wheel weights tumble lubed with Lee lube for a few years then moved on to half wheel weights and pure powder coated. I size them .002” over and work up a load for the most accurate in each gun they will be fired in. Amazingly my Glock 17 and AR-9 like the same load, one 9mm 1911 likes another, and the other 1911 and the wife’s Ruger SR9C like another. Everything is loaded for accuracy which usually runs about 50-80% of max so I’m not pushing them real hard.
 
Replacement barrel is and option, do to local laws. I am located in northern Europe.

Leading is not a problem do to the fact that we powder coat.

I think 357 can't be way off, when it works boolits coated boolits from factory.

Thanks for the replys, but I still looking for the golden answer.
 
I would think that the commercial bullets in the link are soft lead under the copper plating and coating. Soft lead should give the best accuracy but also has the highest likelihood of leaving lead in the barrel. If I were you I would try to size .358" , maybe slug the bore first. Then try with the your softest alloy and see how it does.
 
I shoot a lee 125 grain(?) round nose.
I powder coat. I isually load em down to 3.8-4.0 grains hp38.
I don't own a Glock but my son and dil have a bunch. she shoots the 34 and we have never seen tumbling and the accuracy seems to be on par with fmj.

No leading problems with the PC bullet.

What mold do you have ?
 
I cast and shoot for a handfull of 9MM pistols. None of mine give any problems. None are Glocks however. I would first thing get your calipers and measure both the working and poor shoting bullets. There must be a difference. It might be as simple as the powder coating is different and yours is stripping off in the barrel. There are specefications from the factory like hardness, size, type of coating, something is diffetent. HyTec coating that a lot of companies use is not regular powder coating so finding out what the exact bullet you are trying to copy is will be your route to success. Good luck and let us know what you figure out. It helps everybody.
 
Pull a bullet and measure the base diameter. Unless you’re using an expander meant for lead bullets it’ll probably be to small.
 
Okay, I can see a lot wants to help but over look a lot of information.
And I have left out equally as much information.

We are only talking about Glock stock polygon barrels.

We powder coat so leading is not at all a problem.

As information the H&N bullets in the link is soft lead. 8 BHN. Whit a clear powed coat after copperplateting.


DukeConnor:
We have a lot of molds, they are not at my house so can't say exactly which one's. But I know there is a Lee 125grn 356 RN in between. But it doesn't work for us in the Glock barrel.


The next thing we try will be to size to 358 in soft lead.
 
The bullet you are using is both copper plated and powder coated. Being softer than you probably are casting it is bumping up the base and sealing better. It has less chance of not working in the barrel than a plain lead bullet with powder coat. Many over here in the US use copper plated with no other coating in a polygonal barrel with good results. A fair number of people have poor results using lead in polygonal barrels and they are not all Glocks. The idea of finding a different type of barrel is a good idea. Otherwise you just might find you are just chasing your tail and never get the results you want. If you can find any Hi-tek coated bullets to try see if they work. If those do not probably no lead bullet will work, then a new barrel is my answer.
 
Sometimes this stuff gets frustrating but stick it out and you will figure out your recipe.
It just means more range time which is always good
 
My gen 3 17L seems to like the harder coated bullets to anything soft.
Definitely pop can accurate at 25 yards with commercial cast/coated which usually run around 18 bhn.

My Kimber with land and groove rifling does well with soft bullets, but I suspect soft bullets ride over the polygonal rifling in Glocks and don't get the spin they need.
