I don't believe that bullet has a cannelure, be sure to use a pretty stout taper crimp! COAL on all 223 AR's is 2.25" Max.

Ivan, that sounds like a plan! Accuracy Load = VV N133 @ 23.5gr = 2,900fps
My preloaded (30each) mags have 24.0gr and 24.9gr.
At 23.8gr Sierra says ~2900fps (20in barrel), so... my 24.00gr load may be very close to that 2,900fps. THOSE should be just fine. What I am wondering about is the 24.9gr work-up load. Other than Sierra, all other sources say 23.5gr MAX.
AND YES, Engineer1911 is quite correct that I have zero experience, not having fired any of these loads once at this point. I have valued his advice for quite some time now, and agree. FWIW, I am just a scaredy-cat 68yr old man with prior experience with +55 broken bones, mostly ribs, back, and know all too well about being on a ventilator for over two weeks, less than 5yr ago.
Not wishing to repeat that experience, I am keeping as low a profile as I can. I have even curtailed my Harley riding this year, for the same reason...
Last I checked, Texas ranked number two, behind CA, in having most covid-19 cases...
Accounting for the length of the barrel 20in vs 16in and roughly 100fps loss, load data suggests 24.5gr for 20in barrel at 3,000fps. So, if I figure this reasonably correctly, my 16in barrel will push ~2,900fps at 24.5gr... smack dang between the two test loads I have waiting to shoot... Sounds safe enough to blindly load a batch. Not looking for BR competition, just reliable and reasonably accurate.
All said and done, I have just re-furbed my shot-up HG range target at home, and dug out the lead. At least I can get back to that with gusto, not overly paranoid with a mask, just ear plugs!
Trying to keep safe AND keep shooting.
