429421 meplat diameter

[Mark]

After reading Brian Pearce's article on Keith bullets in this month's handloader, I wondered when did Lyman make the 429421 with a .300 meplat? Are the new molds still .270?
Thanks,
Mark

My recent vintage 429421 4 hole is .270. My several years old RCBS 250K is .300. S/F......Ken M
