Reloading - Blending powders?:

Quick reloading question: I find myself using large quantities of IMR 4064. I don't choose to keep case quantities in my condo. Is it OK to blend different lot numbers and manufacture dates to maintain consistency or should you just chrono and check characteristics from lot to lot? Thanks....

Tony Y,

TOO MANY VARIABLES! Moisture content, or lack of, Age, slight changes in batches chemistry while mixing can be most bogus bad news for the Iselin Dude. You're better chrono'ing each batch loaded and keeping up the log book.

Mixing powder lot numbers is not really recommended, but if you do, start again from a medium load and work your way up. I've done this several times without adverse results, bbbbuuutttttt, make sure the powder is relatively new. You can call up IMR and ask the production date of certain lot powders., but I still wouldn't recommend it.
