    I had a Bushmaster with a 14.5"bbl. It really liked 21.6gr of IMR4198 and the 55gr SptBT bullet.

    I've loaded for a friends 16.5" T/C carbine and my Rem M7 w/18.5"bbls.

    They prefer Win748/BL-C2; as do most .223's.
    I use 26.9-27.5gr under a 55gr bullet, seated to 2.221" oal except for the plastic tip bullets which I seat a tad longer.

    Others will recommend H335. I didn't see anything exceptional with it.

    My next prefered powder is RL-15, but it is typically compressed. It is exceptional in my Rem M7 with the Sierra 65gr BTSP which is decently accurate from the 1/12" twist, but your results my vary. Sierra recommends at least a 1/10"twist. (I get 3,000fps and kills deer like a .243wcf w/100gr bullets....) As I said, exceptional for a 18.5"bbl in .223.

    I don't care for the lighter bullets in the .223 as BC and SD are low. At and beyond 250yds, the 50gr and heavier bullets out perform the lighter ones. Accuracy with your barrel will favor the 50-52gr bullets. For all-out accuracy, try either BL-C2 or H335. Also perhaps good performers are TAC or "Exterminator" from Western. I've never used either of these so can't speak from experience.

    26.7 grains of 748 with Hornady's 50gr V-Max shoots great in my Remington XP100R pistol and also equally well in a Rem 600 in .223. That's with RP brass, RP 7 1/2 primers at a col of 2.205".

    I have used IMR 4198 in several .223's including a Contender with 45 to 55 grain bullets with good success.

    HI: I shoot a T/C 21"barrel w/1in14 twist. The best loads in my carbine are with 52grn V-max,26grn Varget,Fed 205, It chronographs 3078 fps, 28.4 es,11.3 sd. You'll also find 26 grn of H4895 is just as good and a tad faster 3200fps.
