most of my casts will be used in pistols, but my .44mags will be used in rifle/pistol. it does suck that i'll have as much tied up in 1# of 50/50 as i will in about 100# of ww

Get a gas check mold for those .44s and you can use WW in that caliber as well.

50/50 is a little pricey, but tin is very desirable in bullets. If you want well formed, shiny bullets, add one ingot of 50/50 to a 20# pot of WW. The difference is obvious. Once you see the quality of the bullet, you will understand.

i hear that cast bullets with some 50/50 will produce a slightly larger bullet (maybe .001) i have a .429pb mould and my barrel slugged .429 they drop at .429 with ww. this mould won't be any good to me unless the 50/50 can get me to .430...thoughts?

The less lead, the less shrinkage. The 50/50 will probably help. Wheel weights (the clip on variety) are generally about 4% Antimony and 96% Lead. Adding 1 1/2 - 2% Tin will help your shrinkage problem.

If you have used a mixture of clip on and stick on weights, you may have screwed the pooch. Stick on weights are pure lead.

Your cast bullets coming out at .451 is too small. The bore of the gun I assume is .452. The cast bullets should finish at .453. For heavy volume shooting I shoot as cast #2 alloy and tumble lube. No GC below 1,500 fps.

is it common for a mould to drop exactly what they're rated for? or do they generally drop 1 size bigger. my Lee is rated at .429 and drops .429's

It may be that you are using an alloy that is too high in lead. Lead shrinks when it cools (freezes).

It is possible the mold is out of spec. Make sure you have a proper alloy and check again. If still undersize, contact the manufacturer.

Do they not shoot accurately? Just because they mike at .429 does not necesarily mean they will not shoot well out of the gun.
