Lower limit test load for .223/5.56?

[danpass]

Anyone ever come up with one?

Sort of a "if it runs this it will run anything" type of benchmark load?


I prefer to not even chamber Wolf/Tula lol

Any commercial brass round should function correctly in a quality rifle. To truly answer your question, you're looking at loading your own. You could begin with the recommended starting powder load and work down from there, although if the starting load cycled the gun properly and locked the bolt back, I'd personally leave it there.

I used to have that approach...

Then I learned a lot about over gassed guns. So in my eyes a gun that'll run weak ammo is more likely to bounce you around with full powered ammo.

I like a gun to be able to reliably run commercial 223, but I don't want it to have excessive bolt speed with 5.56 pressure ammo.

I'd just look at several loading manuals and start with the lowest grain charge per the manual/s.
