Frosty bullets

[Dr475]

Other than appearances are frosty bullets a problem?

[Tom W.]

No. Not at all.

[MyFlatline]

Not for me, they take powder coat great also..

[Toymaker]

The lube sticks to them better. Likely your lead or mold are too hot.

Dr475 - welcome to CB If you decided to start casting to save money, forget it. You won't, you'll just shoot more.

Frosty boolits (lead bullets) are generally caused by the mold being to cold. as stated above, they load and shoot just fine, many prefer frosty boolits. the trick is to cast ALL your boolits the same to get close to the same weight. Watch the sprue puddle and get your rythem consistent.

Casting boolits (lead bullets) properly is a science, once you know the basics, not a hard science.
There is a lot of good information on CB. The Google search (top right of every forum page) is a gateway to all the knowledge on this forum. IF you can’t find your answer there ask the question (Please be as detailed as possible, pictures help http://castboolits.gunloads.com/show...g-screen-shots I would be very surprised if there wasn’t someone on this forum that could answer ANY question you might have)

1. Boolits need to be cast .0005 to .003 over the slugged diameter of your barrel for accuracy and to avoid leading. If the fit is wrong nothing else will work right.
a. slugging a barrel (it is safer to use a brass rod or a steel rod with a couple of coats of tape to avoid damaging your barrel http://7.62x54r.net/MosinID/MosinSlug.htm
b. chamber casting https://www.brownells.com/guntech/ce....htm?lid=10614
or pound casting http://castboolits.gunloads.com/show...rifle-chamber)
2. the right alloy needs to be used for the velocity and purpose of the boolit (don’t fall into the trap of going with to hard an alloy
Economical way to easily test lead hardness

Some alloys harden over time

different alloy’s different end sizes

3. velocity the bullet needs to be pushed hard/fast enough to get the proper spin, have the proper velocity to accurately reach the target but not so hard as to be dangerous or strip the lead off in the grooves instead of spinning the boolit..
Powders range from fast to slow, you need to choose the right powder for your application.
Loading manuals list the best powders for certain calibers and boolit weights.
NEVER use any posted noncommercial load data without first checking to see if falls in the safe parameter for your firearm!! There are several firearms out there that can handle much higher pressures than others!!

Yeah... They were really hot. Do you water drop? The only thing I see when mine are like that is sometimes the sprue plate wipes the back of the slug and deforms them a bit. Not a big deal.

[Eddie17]

I’ve found that frosty coated boolits are due to running a mold hot!
An in my experience causes a lighter weight cast boolit.
My 2 cents.

[Outer Rondacker]

Welcome to the forum. We all started out getting a few frosty ones. Mine shot just fine. Remember you can always toss them back into the next cast.

[Rcmaveric]

Frosted bullets don't make a bit of a difference. Shoot em up. Some times mold like to be run hot, such is the case with my aluminum molds.

[bayjoe]

Frosty bullets sure make powder coating stick to em.

[gwpercle]

The easy answer is, they get frosty when mould and metal both get hot, I like to cast at the just getting / lightly frosty temperature for good fill out and sharp lines.

They are no problem...CHOOT EM !

Never had a problem from frosty bullets.

Never had a problem from frosty bullets.

thank you all

I reject bullets until everything is hot enough to give a light frosting. Frosty bullets are good bullets.

Same here for me "No frosting = Not ready" Welcome to Castboolits ask questions and before you know it you'll be knee deep in saving money.

Yeah, right. I have saved so much money with this addiction that I am going broke! LOL. Welcome brother, you will love this place.

I agree . Frosty is cool !

[crappie-hunter]

Veral Smith in his book,( jacked velocity with cast bullets), said he doesn't consider keeping bullets till they start to look frosted.

[Walter Laich]

about the time mine start to get frosty I'm out of lead in the pot; just happens that way

I do notice during Texas summers they get frosty sooner. I usually have a fan on me and the mold to slow this down at bit

[Frosty Boolit]

Talking about me behind my back! Of course frosty boolit is okay!
