sizing 44

[686]

for those that cast for ruger sbh what size do you size the bullet? my cylinders are .432. i do not know what the bore is. i was thinking .430 or .431 . also do any one use lite-gun powder? i shot some with jacket bullets but do not see listings for cast.

686,
My S&W Model 624 and Model 24 have .432" throats and I size to .433".

You probably mean "Lil' Gun" rather than "lite-gun". I don't use it, so can't help.

My Super Blackhawk's cylinder throats run about .431". The bbl slugs out to about .429" - .430
". I like to run .431" to .432" boolits with Carnuba Red over a mid load of WC820...

For both 94 Marlin, and Ruger sup BH, I go .432-.433. I find that it is always best to go big, and I get little leading as a result.

I would size to .432 as that is what your cylinder throats are and if you are casting with softer alloys then having the larger sized bullet is better due to the swage down possibilities as you seat the bullet into the brass casing. I've seen the case squeeze a bullet's base down as much as .001-.002 with softer alloys. If you plan on hard alloys then you should still be ok with .432 as well providing the loaded round will fit in the chambers (which is should chamber with no issues). Also noted many people size bullets larger than the cylinder throats (me included with softer alloys) and have great success as well.

If you haven't read this already here is a thread I posted up regarding bullet diameters and how it can be effected by the brass during the seating process.

Lil Gun is a powder that has been used with upper end loads with success and although I am possibly a bit over cautious of it, I have read post where it has created forcing cone damage. I personally will stick with AA#9, 2400, or H110 for my mid-upper to upper loads

I use Lil'Gun in my .44's, it's about the same burn rate as H-110 in the .44, different (faster burning) as the caliber increases.

My Ruger RH has .432" throats and a .430" groove diameter.

Lil' Gun is a wonderful powder. I just started using it and it is very clean burning; +1 over H-110! I really like it- meters really well, same if not a little better velocities as 110 even with a standard primer, and did I mention that it burns clean?

My SBHH slugs out .430" to .4305" The cylinders slug out .432" to .4325". I've been sizing to
.430" and have been getting some leading. I'm about to get a .432" die for my Star. I've tried
2400 and #9 and like the #9 a lot better than the 2400.

If your cylinders run .432, I would go with a .432 boolit.

Other then the RD molds I don't know how much luck anyone has to find larger molds. They almost need to be custom.
Most molds will need hard lead, water or oven hardened so they will grow a little.
I would not trust Lee, Lyman or RCBS to cast large enough. Seems as if after all these years, mold makers would know what we need. :groner:

[686]

i ordered a .432.5 star sizing die. last night i casted some with my new rcbs 240 gr sil. mold. perty hard lead. i was getting .430-.431 . i will add more liontype next time.

686,
"Beagle" your mould. It'll drop fatter boolits.

[686]

beagle is that the same as laping it? will you incress the steel mold that much?

[Three-Fifty-Seven]

Beagling is simple putting something (alum tape) in between the mold blocks to hold them out a tad, makes fatter boolits . . .

[686]

DO not think i will do that. the bullet would be out of round.

[462]

686,
Search beagling.

Your ultimate solution is up to you, but aluminum foil tape is inexpensive, the method works, and it is reversible. Lapping is another solution, but it is permanent. Customs moulds are expensive. I've beagled and lapped, all with the desired results. I can't affore a custom mould.

[MtGun44]

686,

I suggest you listen to the experts on this one. Beagling has been shown to work very
well and as 462 points out, is cheap, quick for a test, and reversible without any damage.
Turns out that out of round a touch is either eliminated during sizing or during the launching
cycle.

I have a Lee mold that drops them at .433 with my alloy. It's the big one, 310 gr. IIRC. They shoot about 3" at 50 yds. with my shaky grip. Do kick some though. Also, I just read a post on the CBA forum by Dale53, a .44 authority in my opinion, he says he uses .430 most of the time with a bhn about 15, plain base to 1500 fps no leading. I'm still perfecting my .44 loads.

Interesting with a plain base at 1500 fps. I wonder what weight his plain base bullet is for this velocity???

[dualsport]

I think he was talking about the Lee 430-310 which he designed. I'm not positive about that, I'll reread the post next time I'm there. Dale has a lot of posts here and on the CBA forum if you want to read up on cast boolits in the .44 Mag. I'm not saying he's the only one around that knows his .44s, just that he's shot 'em a lot and shares his knowledge. I know he helped me with a problematic SBH. You can check out the CBA forum too, there's a lot of info available there, just not the volume you get here. I've read that gas checks shouldn't be necessary on handgun ammo, but they do make it easier to prevent leading for me.

[LAH]

I size to just under throat diameter. I like being able to push the bullet through the throat without having to strike it. Works for me................Creeker

[chaos]

All of my SBH's like .430 WDWW. Give me good enough accuracy with no leading, so I never felt the need to try anything else.

Beagleing a mold is easy, takes only a few minutes and if you don't like it you can take it off just as easily as you put it on. As for out of round, for some reason they don't come out of the mold too out of round. When you run them through your sizer they will come out round. Beagling has saved a mold for me. I bought a roll at Ace Hardware for $3.99, one roll will last a life time. jmsj

[armyrat1970]

A cast boolit .001 or .002 out of round is not that bad.
Hell, the average sheet of paper is only .003.
Does that make that much of a diference?
