Do you size

Do you size your cast boolits?

I do not size.
I always shoot as cast.

I do.

I have found that my bullets as cast differ in diameter along and across the mold divider line by more than .001".

Some ya do and some ya don't. Depends on the chamber cast or slug size and the cast boolit size. About .002 over slug size is what I aim for.

I do. I run them all through a Lee sizer, mainly to "feel" any that are undersized. I recycle those. I have a bunch of Lee sizer dies, some special ordered to meet my needs.

Yes and no. I use the Lyman Lubrasizer, but my boolits drop right at the size I like, so my die is just kissing them. I prefer the lube-sizer to to pan lubing. For 45 Colt (Long Colt) I prefer .454 boolits as my cylinder throats are .453 and my barrels a tight .452

Oh, and for long skinny cast boolits I like the Lee sizer. For plinking I just tumble lube, size and re-tumble. I let the tumble lube cure for days or weeks before handling. For hunting I use Lee case lube and then the Lee sizer. Then I heat treat the WW alloy boolits for hardness, then tumble lube and cure. They are very very hard and brittle at first, but after curing for several months the hardness is just right and they are very tough and the Lee Tumble Lube is really cured well.

I size everything. Just to eliminate a possible problem. I would as soon size with a sizer die as the cylinder throat of my revolvers.

Ditto. I prefer to leave as little lead in the bore as possible. :lol:

Yes, I do size. "Kinda" feel if all the bullets are the same size they might be a "smidge" more accurate.

I wish they made a sizer .001 or .002 larger than the caliber l'm casting for. It would also be nice if it was easier to lapp a mold to a larger diameter.

The benefits of sizing are, for me 1) assuring the boolit is truly round, 2) reducing the diameter of what ever the mold is dropping, 3) Gas Checks.

Several of my mold need a harder alloy to drop a larger size needed and a few need a softer alloy and a special few don't need to be sized at all for BHN 12 or 13 WW.

I rarely size for pistol and am lucky to have found/traded/swapped molds that drop 'em just right. I don't size just for the sake of doing it. Bullet weight and blemishes are just as important as diameters unless you talking leading. With leading issues the BHN of the bullet also make a big difference. Sometimes boolits can be to hard, sometimes to soft. Figuring out what BHN works for your mold and gun can get a bit frustrating.

Rifle typically get sized just because of the benefits listed above like GCs and some need to be bumped because a harder alloy isn't helping.

buckshot @ castboolits makes custom size Lee and Lyman style bullet sizer dies. On my order it was one day turnaround, and less expensive than Lee custom die.

Thank Helg. I'm a regular lurker over on cast boolits and have posted a few time. The CBA is another nice site. Buckshot is a remarkable man and I like his post/remarks. I have 2 custom sizer and 4 custom molds (303's and MN are all over the place!).

I have a .312 H&I sizer die to trade if anyone is interested.

Lee's custom sizer is only $30.00 and comes with a bottle of lube and this gentlemen can actually beat that price? What does he charge and where can ordering info be found?

Two years ago single Lee custom sizer was, if I remember correctly, $23 shipped. There was a discount for ordering more that one. No plastic, no lube, no nut in the set - only a die, a bullet pusher, and a sized slug - as a proof of size. He asks for desired diameter and bullet material you plan to size from (like soft lead, ww, or linotype) As I mentioned above, the buckshot can be contacted via PM at the castboolits forum.

Lee's website say's they are $30.00 now. I assumed they came with the lube and die/bullet box.
