Duckster,
Some guys don't like OneShot, but for large quantities I have found it to be the best thing since sliced bread. You've gotta shake it well before spraying and then have something else to do for a while. I honestly usually wait an hour. I have gotten busy and not resized until the next day with no problems. OneShot is not as slick as Imperial, but it sure is handier.
I do use Imperial when re-forming brass or necking down 308 Lapua to 7mm-08 for example, but when preparing several hundred rounds for a prairie dog shoot, out comes the OneShot. Good luck and always use what works for you.
