One of the large full time SWAT teams here uses Hornady 75 gr OTM on entries, 62 gr Fed Tac bonded JSP (LE223T3) for barriers, while patrol officers have 64 gr Win JSP (RA223R2) from the state contract––everyone used 55 gr FMJ for practice; out to 100 yds or so, there is minimal POI difference, especially when shooting fast, on multiple targets, while on the move.
With a 1/9 twist AR, I personally would be inclined to use the 62 gr Federal bonded JSP Tactical (LE223T3) and the similarly performing 55 gr Federal bonded JSP load (Tactical––LE223T1 or identical Premium Rifle––P223T2), along with the Nosler 60 gr Partition JSP, Remington 62 gr bonded JSP, Speer 55 & 64 gr Gold Dot JSP's and identically constructed Federal 62 gr Fusion JSP, or possibly the Barnes 55 gr TSX. Other options include the 69 gr SMK OTM, 68 gr Hornady OTM, Winchester 64 gr JSP (RA223R2), Federal 64 gr TRU (223L) JSP, and Hornady 62 gr JSP.
