"What would a $2,000 Geissele Super Duty do that a $500 PSA door buster on Black Friday couldn't do?" - Stopsign32v
Another TAC vote here as I shoot mostly heavy bullets and it meters so easy on the dillon 550. I have used cfe223 but found it more finicky in load development and extremely dirty for carbon fouling.

I like AR Comp, CFE223 and Varget.
I’ve used all 3 out to 600 with 77 SMK.
Also the AR Comp performed very well with 62 FMJBT.
All of 77 SMK are under 1 MOA if I do my part.
20” Heavy Wilson Combat barrel.
1 in 8 twist
All was in 2,700 FPS range.
AR Comp only varied in 7 FPS in 10 rounds on chronograph.
Others were in 20 FPS range.

I will be the weird one and suggest N540. Only powder that I have ever used where my measured velocities agreed with published data. Rifle used was 20" Colt A4. N540 from this rifle produced best precision with increasing velocity. 69gr Nosler was the projectile.
Truth. I used n320 for 9mm range load.
Crazy consistent, burned clean enough the glass on optic never got “smoked” like a lot of powders.
Fortunately it became unavailable for months and I moved on. Twice the amount of my current powder for same price.
Very good stuff though.
A true "Gun Guy" (or gal) should have familiarity and a modicum of proficiency with most all firearms platforms.

Some manufacturers publish data gleaned from test barrels and universal receivers. Hornady used to (and may still) list the specific firearm used to gather velocity
