For those with the Lee 452-255-RF, what is the average diameter that your boolits are dropping at?
Thanks

There really is no avg, especially with Lee molds. I find they mostly cast smaller than I like by .001" using range scrap. My old 2cav drops right @ 0.452" with range scrap, 258gr @ 10-11bhn.
Mine drops right at 452 just about all the time,close enough that after several hundred rounds down the tube I just haven't checke lately.

I've had two and never got either one to drop larger than .451. I, consequently, got rid of them.

My 2c drops .454-.455 around 260grs with range scrap.

My fairly new six cav drops @ .454 w/ COWW. Pretty much perfect for my purposes. Something odd about the base but that is likely a sprue plate adjustment issue.
50/50 is coming in at .453-.454 which is fine for me
