An all WW alloy has about the same properties as Lyman #2 so you shouldn't have to add any lead at all unless you want softer bullets. Would suggest you add about 2% tin by weight which will help WW alloy fill the mould better.. . . Also what ratio of lead/WW or whatever should I use for these pistol bullets. Thanks
Let me understand this properly, you deliberately size cast .45 acp bullets at .451" ?For my Kimber:
- with a 1/20 tin alloy (BHN8), my bullets are sized at .451" (otherwise at .452", I get leading on the begining of the barrel).
- With 50/50 lead-linotype (BHN15), my bullets are sized at .452" (otherwise at .451", I get leading at the end of the barrel).
For both, the accuracy is the same. My mold is a Lee RN 230gr bullet.
This is 100%, completely, and utterly false. Bullet sizes vary by several thousandths of an inch, as do bore diameters. It is VERY common for shooters / casters / reloaders to experiment with several bullet diameters when trying to find an accurate load. Manufacturers make bullets in different diameters and casters use different sizing dies to achieve different diameters. I've seen .45 bullets as large as .454, as small as .451. A lot of folks "slug" their bore to find its exact diameter, then experiment from there.Let me understand this properly, you deliberately size cast .45 acp bullets at .451" ?
It would be odd, extremely so, to size a .45 cal lead bullet at anything other than .452" there is no other size, .452" is the only size...
Seems that your either a troll or just don't bother to read the OP, nevermind the dates of the OP and following replies.I am going to start reloading my 45 with cast bullets from Lyman mold #452374. This is a non gas check bullet 225gr.
I slugged the barrel and the grove diameter is .450
My question is what size sizing die should I get? .451 or .452
