I have my fathers old 452374 and I've cast some boolits with it and went to size then with my RCBS .452 die and lyman 4500. The first couple and only ones I've sized have lead pushed up from the bottom of the boolit.

They are dropping at .454 using WW lead and Lyman #2 from Roto Metals. Not sure what to do here.

Are you getting flash around the base of the boolit or in and around the bottom lube groove?

Wait a second here, anyone else find it odd to hear someone complain of a Lyman mould casting oversize?

Size those bullets down and they will be fine. Be happy you have a good mould.

No problem at all. Run them into a .452 sizer and go on. .002" is just fine for sizing.

My older, four-cavity 452374 drops boolits at .454" and they are sized to .452" with a Lyman 4500 without any problems.

btroj, I love those older Lyman and even older Ideal moulds, and the fat boolits they produce.

I'd like to have an older 358311 mold.....

Size to .452" and count your blessings. Everyone I've owned cast small or right at .452"./beagle

thank you all. just seems odd that there is a tiny ridge of lead that has been pushed up. i will size, lube and load.

Whitefolf68,
Is the sizing the older style that does not have the O-ring? If so, it has a straight opening with a sharp edge, and that is the culprit. The die is rather hard, but you should be able to chamfer the opening.

The newer, O-ring style has a tapered opening that eliminates the possibility of base damage.

My mould does .455-.456. I sized to .454 & lubed. I can size down from there need be. BTW this is from air cooled wheel weights.

You may not need to size them at all if .454" puts them .002" over nominal bore diameter as your post implies; slug your bore.

Bore permitting, lube 'em, load 'em and shoot 'em.

Bigger is better.

It is the newer style with the o-ring at the top of the die. I assume that is what you are referring too?

Since you have the newer, O-ring version, I don't know what may be the cause.

Don't worry about it. Remember, when you size the boolit down, the lead has to go somewhere. As long as the loaded round will chamber, your go to go.

What kind of lube is that? Where do you get it? How hard or soft is it?

LAH's version of the 452374 looks to be the "extra pointy" variant.

My older 452374 casts a less pointy and probably heavier bullet. Lyman's getting away from the true ball radius a bit.

Sizing .454 to .452 is NOT a problem.

I regularly size bullets down from .004 to .006 and despite what you have read, they load and shoot just fine with no loss in accuracy.

That is Ballisti-Cast hard lube. http://www.ballisti-cast.com/

This one is different than most. Notice the mould suffix FX, is yours like that?

Whitewolf - If you mix the WW's with Pb, say 50/50, the boolits should come out of the mold a little smaller. You might give that a shot. enjoy Mike

They seem to load and chamber just fine so far. We'll see how accurate they are when the weather breaks again and I can get to the range.

I will see about adding some pure lead too.

Thank you ALL!

Consider yourself lucky to have a Lyman mold cast on the large side.
My new 452374 casts .450
I have beagled it to .453 and then size to .452.

Lyman has really lost the plot on Quality control.
