Time does fly.

Have been shooting some 223 bolt rifles this Spring. Used up a few 100cnt range boxes that I had loaded. Getting ready to do some re-loading of these and noticed that I had loaded these in 2001. Holy Cow, can't believe 20 years has passed seemingly in the blink of an eye since I last loaded for the .223. Been shooting plenty of commercial stuff over that period and never thought about it. Decided to make up some precision loads using 40 gn Hornady Vmax that I use for the 5.7 x 28. Load for the .223 will be 23 gn of IMR-4198 which should produce right in the neighborhood of 3500 fps.

Hope I get to use the new ammo up in the next 20 years.

I was commissioned 38 years ago last Sunday. Seems like yesterday.
A V-Max isn't a match bullet. And 23 grains of IMR-4198 is slightly over Max(22.2 on Hodgdon's site) for a 40 grain bullet. They say that load runs at 3,652 FPS out of a 24" 1 in 12 barrel. 53,400 PSI.

Chances are I have had this 4198 on the shelf since you were commissioned so it has a right to have lost some of it's zip as I am sure you have over that period of time. Out of my 20" 1-9 barrel it chronoed 3375 to 3450 today. 10 rnd at 100 for a 1" max and .5 average.
