I size some first, depends on how fat they cast.
I set my oven to 400° F and bake for 35 min.

I don’t stand mine up and the bases are fully covered as well.

I ALWAYS size last. You size to fit your barrel/chamber correct? Why size any other time? You need know the diameter to build a loading. So size last.

Baking requirements are on all manufacturers product or website. But generally 20 min after flow/gloss @ 380-400 cures the powder.
On a large rack if heavy 45 cal that is 45 ish min bake. On 50 22/40g hp its 25...

Uh, with some molds I install gas checks first, this sizes the bullet when using the Lee push through dies. Then final sizing after powder coat.

My Lee 312-155-2r drops pretty large, it benefits from this routine of being run through the sizer twice. They drop from the mold at .3135”, size/install checks to .311”, powder coat makes them .313” to .314” then they get final sized back down to .311”.

It’s important to have a polished and clean die. I do run these through dry.

But again thats your choice. A GC can be seated without sizing.

So nothing directly to do with Powder Coating.

Why size any other time?

CW,

First I would like to
Thank You for honoring my right to choose!

Second, Thank You for asking the question I quoted above. I will always try to help out one of my fellows on this board if they ask a question!

And lastly, I wanted to say that I too
ALWAYS” size after powder coating!

But SOMETIMES I size before powder coating.

Is this wrong? Have I broken one of Mr. Venturino’s rules?

Did Mr. Lee tell us that his BHN formula would only work if we sized our bullets after powder coating. I’ve never seen Lee’s formula written that way, BHN = (PC+PB) Pressure / 1,920.

Can you please tell me where these bullet powder coating Order of Operation rules you are quoting come from. I’ve never come across them in the Bullet Powder Coating Manuals.

I seem to recall reading about some Maxiballs that were to big to load in a certain muzzleloader last week. Did you size those Maxiballs after powder coating? Or does “ALWAYS” sizing after PC only happen “sometimes” at your house?

I am looking to trade with someone for some powder coat paint I have for trade items (1) 223 projectiles swaged with 22lr caseings (2) 44mag projectiles swaged with 40cal casings (3) 30/30 cast they have gas checks and are lubed and sized (4) 45 acp 200gr swc cast projectiles the reason I am posting this is I can not fond powder coat paint here except at harbor freight which I was told was not good for powder coating bullets let me know if you can help me thank you D Crockett

@D Crockett , we get off track here a lot and it leads to some very interesting and enlightening fodder along the way, so if no one responds to the offer to trade, don't despair.

I butted in and lead things off track too, but the information I got may help YOU too. On @CWLONGSHOT 's advice (to a neophyte PC'r), I went with Eastwood powder foro my maiden voyage, but their shipping was twice the cost of a pound of powder. I called Eastwood to make sure that was right and they said it was and offered no other option. On @Joshua 's advice, I checked on Amazon, and waddya know! Eastwood sells their powder there for only a couple bucks over the cost of a pound on their own site, and you can get free shipping if you buy over $25 worth of stuff from Amazon on that order.

I DO SO HATE dealing with Amazon, but I ordered some and a few other things I needed - and it shipped like the next day - due tomorrow already!

Here's the funny/cool part - Amazon never fails to present to me the most ridiculous and unrelated "suggestions" based on my browsing and purchases. When I put powder coat paint in my shopping cart, a ton of CASTING and RELOADING suggestions popped up!

Bottom line is we do what the situation requires to our best estimation of best way to get there using the equipment we have.

I actually turned and ground a cherry and made a bullet mould which, for once in my life, enables me to simply cast, coat and load. No sizing at all. Aside from that, I too always size after coating and often before as well. In fact, I often seat and partially crimp gas checks using the Lyman equipment, then nose first through a Lee die, then nose first in a form die to clean up the whole bullet. Why? Because groups at stupidly high velocity. YMMV.

My NOE 454424 drops a nice .455 bullet. After coating it would be .457 and I don’t like the effort required to size those to .453.

I size .453, coat, then resize. I often resize close to whenI will load them so I size put any growth they acquire after a bit of resting.

In the end it all depends, for me, on how far the bullets are compared to desired size. I just don’t care for sizing down too much in one trip thru.

Woah guys....

Ease up a lil here. Im not telling any one they must do anything!! I CLEARLY said what I do. I offer it as it works for me and has worked for years. Id put my tenure with PC as substantial. I have too many colors to count and I believe most have seen my racks of bullets. DONT mean I am right, but it works for me so why not you?

I know many hate or distane the Powder Coat. But Im suprised at you Josh.

Do you size your muzzle loader projectiles? Cause I never have. When I did it I stated plainly it was not needed I just wanted to.

As for sizing "fat" bullets. YES I do it all the time! Wr all know they harden with time. So why wait to size and bullet you already know is fat?? Its only gonna get harder!

Also those of you still sizing on a luda sizer dont understand a push thru is a different animal. And as long as your alloy aint buku hard you absolutely CAN size bullets a few thousands past your comfort zone in them. But NEVER in a die for a ludasizer!

When I started PC I hd a die made thata accepted lyman dies for the 450. I broke a press using that trying to size fat PC bullets. It took some investigating but soon discovered the issue. Bearing surface. So YES 100% I can size bullets fresh cast thru a push thru sizer nearly .010 above diameter. I size 45/70 dia bullets some .463 range down to .454 REGULARLY. Key is size quickly after cast. Yes they sometimes change a bit with time. But a simply second pass only needs few .000 and it is easy to accomplish.

Back to my maxi ball issues. Again where im suprised at Josh as its just a poke. It was because if hardness. I used my RF lead softened with pure and didnt figure correctly. I stated I never have sized a muzzle loader bullet and maybe as pure lead its OK but it definitely isnt if they are hard.

Not upset but the comments have forced me to be a bit defensive to explain. Largly I offer little here as I know and realize many have far more knowledge but I speak proud of things I know. ONLY to try to HELP, im not seeking anything but that.

Not mad at all. That’s why I went with purple and a rainbow unicorn!

I’m really much more of lurker than a poster. I don’t belong to many of the boards that I follow. I search for a topic and then data mine obsessively until I feel like I get a handle on a subject.

Often when I am researching a topic, let’s say for example Coleman Stove restoration and repair, I will inevitably come across a fight between two well know members over methods of restoration. Often the fight has less to do with the method, and more to do with one member asserting that there is ONE hard and fast rule on how to do something.

We all have the right to do whatever works for us. There is no hard and fast rule on when or even how to size PC bullets.

As to sizing muzzleloader projectiles:
Over the last week or so I’ve been intensively following the exploits of IdahoRon and IdahoLewis across multiple boards(multiple handles also, with a few bannings). Those two do a lot of sizing to muzzleloader projectiles, both grease groove and paper patched bullets. I’ve even got a .501 sizer on order that I will open up to the size that is appropriate for my gun.

There is another guy I ran across on one of the state based hunting forums, Michigan maybe, that is casting the Lee C501-440-RF, powder coating it, and then sizing it for his 50 cal muzzleloader, he greases that bullet and loads it over a lubed wad.

Nothing makes a round ball purest madder than a guy casting a bullet intended for a center fire pistol, slathering it with plastic, sizing it on a reloading press, and then taking it out hunting.

I’m not mad at you. I’m mad at the WDFWL commissioners who canceled our spring Black Bear Hunt! No rainbow unicorns for them!!!
