Precision Delta OAL???
I'm trying to figure up a starting point for loading with Precision Delta 9mm 124 gr FMJ RN bullets. The load data for a Sierra 125gr FMJ RN 8120, in the Hodgdon manual would seem to be a fairly close match.
The Hodgdon data calls for an OAL of 1.090 for the Sierra bullet. According to the Sierra data, the Sierra bullet is .581 long. That's about .020 shorter than the Precision Delta bullet. So I'm looking at an OAL of 1.110, but that OAL puts my Precision Delta bullet in so deep it's past its ogive.
That also figures out to be a seating depth of about .250. That's kinda deep ain't it?
So I figure I'm going to have to increase OAL. Right? What I'm wondering is what is a good average minimum seating depth for a 9mm bullet? (assuming no issues with magazine fit/feeding/plunk test.)
CONTACT YOUR SENATORS, REPRESENTATIVES, AND GOVERNORS, AND TELL THEM YOU OPPOSE FURTHER GUN CONTROL!
They're politicians. If you identify yourself as a voter, they WILL
listen. It's IMPORTANT, and the NRA makes it EASY!
