Old post recently revived but I just got back from a PD shoot in NE Oregon, wind was + 20kts. Had great luck with a pair of 20 practicals shooting 32 grain Z-Max at 4200FPS. Very accurate, faster, flatter and more explosive on ground squirrels then the 223s. Longest hit was 330 yrds. Anything inside 200 yrds was an easy shot no matter what the wind.
I did the numbers too in the JBM calculations, 32 grain .204 Z-Max at 4200 FPS vs. 52 grain .223 Sierra Match King at 3500 FPS. Everything favored the faster .204 bullet.
One more thing that was mentioned, no ricochet with the 204 bullets.
If you reload consider the 20 practical vs. the 204 Ruger, if you have to buy factory probably go with the 223.
Good shooting
