greater than .355 bullets
Can't argue that point, save that Winchester itself says 0.357"

See https://rugerforum.net/reloading/379...ml#post4399961
Also: https://winchester.com/350-legend/faq

On the OTHER hand .... Commercial/pulled bullets just now:
Winchester 150 0.355"
Winchester 180 0.355"
Federal 180 .... 0.356"

To be saf[est], I venture Lee sizing down to 356 for jacketed then, although I found no difference in velocity(thereby imputed pressure) between HotCores at 356 vs 357. (I did note that you are seating the HotCores out to 2.27" whereas I'm running a standard 2.26". So I wonder if a throat/final-closure condition is involved.)

My anomalous pressure/velocity spikes were with Lil'Gun/Cast and nowhere else. So I'm really scratching my head until the [other] PoohBahs weigh in....






POOH-BAH: Don't mention it. I am, in point of fact, a particularly haughty
and exclusive person, of pre-Adamite ancestral descent. You will understand
this when I tell you that I can trace my ancestry back to a protoplasmal
primordial atomic globule. Consequently, my family pride is something
inconceivable. I can't help it. I was born sneering. But I struggle hard to
overcome this defect. I mortify my pride continually. Act-II/Part-III
