I don't know. Hadn't thought about it. I'm still playing with the load, though, to see if I can make it just a bit tighter still.
Here's my formula, though:
Bullets: Sierra Match Kings, 53 gr. flat base hollowpoint, item number 1400,
Powder: Hodgdon H322 powder, currently at 21.5 grains and still tweaking the load. 23 grains is the max load.

Trimmed, polished, and matched cases. It doesn't really matter which cases, as long as you keep using the same type. I'm usually using once-fired small stamp PMC's because I've got a bucket full of them and it's good brass.
And I'm single staging them. Yes, it takes some time, but it's paying off on the target.
It takes a LOT of time, actually! A thousand rounds is a full weekend's work!
I'm planning on moving up to a Dillon XL650 soon. If it meters the powder with enough consistency, then it'll speed up the process enough that I might be able to make reloading for hire worth while. But I'm not sure that I want to do that, because I wouldn't dream of selling potentially explosive items without a business license and an ammo maker's FFL (class six) for liability reasons.
