I use an old production, Lee tl sizer die nominally stamped .430, bought new years ago_
cast bullets exit sized at .428.
is it normal or a lemon?

.428" is smaller then normal. The alloy used can make a difference after sizing. The harder the alloy, the more spring back. Larger bullets.
But its not going to spring back .002"

I would first verify your calipers are accurate and correct.
If that die is stamped. 430 and spitting them out 428, you should then check if there is oxide on the ID. Lastly, you have 2 options, pitch it, or hone it out to 430.
400-600 grit paper on a dowel rod attached to a drill will work, take your time and test the size frequently.

.428 is good for 44-40!
A member here might be interested in it!
verifying the accuracy of my caliper first makes sense,Quote:

It's a fair question, but I'm not sure what you consider warm. If you are casting and then water dropping, they will become completely water temp within 3-5 seconds.Quote:

Pure lead would give you the best measurement of the die size

pure lead shrinks the most however... so wait till it is cool to size.
Rotometal pewter has 98% Tin, 1.5% Bismuth, 0.5% Copper. To make a larger bullets, antimony is needed.
...no antimony added, in my last casting session...Quote:

I hope it's a caliber issue. because in any case inserting some sized and dry cast in the cylinder of the 29 shows a slight but constant friction at the exit, and this is probably the question that matters most, as ultimate goal.
If the die is truly sizing to the wrong size call Lee and they will send you a new die! Call do not email!
air cooling, here, mildly warm in my hand but not hot for sure...Quote:

just in case, for this member here:drinks:could be a good enough reason to search for a 44-40!Quote:
