what bullet size?

[barnabus]

what are most of you sizing your cast boolits to in 45 colt or 45 schofield? I see lee has a .452 and .454 push through kits. what would the .454 be used for?thanks

[Rich/WIS]

Older 45 Colts were .454, newer are .452, but this is a generalization. To be sure slug your bore and check cylinder throats.

Depends upon your particular firearm's throat size. I have a couple revolvers that I size the bullets to .452", and a couple I size the bullets to .455".

Size atleast .001 over bore diameter

ill be shooting these in a Uberti Schofield. Normally a Lee sizer is always undersize from what they say it is.Ill probably order the .454 and it will be about .453 id imagine.

Go back and read the sticky. Measure the cylinder throats, not the barrel.

For most modern guns .452 is correct.

For pre-WW2 revolvers .454 or .455.

Bore diameter is across the tops of the lands. A bore diameter bullet will be too small.

In most guns 0.001" over groove diameter will be close to the cylinder throat size, but it is more correct to measure the cylinder throats to use barrel groove diameter +0.001, particularly if the barrel has an odd number of grooves.

No...size .001-.002 over groove diameter. Preferably .002 inch.
